Weil McLain Boilers – Common Issues

Here are common boiler problems for this or any brand. In the next section are Weil McLain boiler troubleshooting tips the pros use to determine verify what is wrong.

1. No Heat At All

A burned-out thermocouple is the top cause of a Weil McLain boiler not responding to the thermostat’s call for heat.

2. Little or No Heat

Insufficient water pressure will prevent the boiler from creating enough hot water to adequately heat your home. Adding make-up water will solve it, but the goal is to determine the cause of low pressure in the system. An early clue of low water pressure, besides insufficient heat, is the boiler making popping and/or rattling noises.

3. The Boiler Cycles On and Off Frequently

There’s something amiss if your Weil McLain boiler is turning on, running a short cycle and shutting off. The clues are hearing it cycle on and off, or you might first notice your home’s temperature being more than a few degrees higher or lower than the thermostat set point.

4. No Heat in a Zone / Too Much Heat in a Zone

When zone valves fail, they either won’t open to allow heat into a zone or they get stuck open and too much hot water enters the zone.

5. Carbon Monoxide Alarm Triggered

It’s wise to have a CO detector near your boiler and low to the ground since CO is heavier than the normal mix of air in your house.

Tools You’ll Need for the Job

Depending on the specific problem you’re experiencing, one or more of these tools will prove helpful for Weil McLain boiler troubleshooting.

Your owner’s manual: Weil McLain boiler owner’s manuals contain helpful information about system operation, troubleshooting and problem resolution. That’s a good first place to start when something doesn’t seem right. Most Weil McLain manuals can be found online, even if the unit is 15+ years old.
Screwdriver set: If you’re going to be taking off the boiler cover, there will be Philips and/or flathead screws to remove.
Flashlight or headlamp: Light will help you see inside the unit and look for leaks at valves.
Handheld mirror: A flashlight and mirror are necessary to see many Weil McLain boiler model heat exchangers.
Voltmeter: This tool will prove handy when troubleshooting anything electrical in your home.
Set of small wrenches: More handy DIY homeowner tools!
Long lighter like those used for barbecue grills: This will be used to replicate a pilot light.

Weil McLain Boiler Troubleshooting

This section reviews common problems and Weil McLain boiler troubleshooting tips to determine their cause.

1. No Heat At All

If the electrical circuit for the boiler is on and the power switch on or near the boiler is on, crank the heat way up. If the boiler doesn’t start, it’s time to check the thermocouple:

Turn the gas cock on the gas line to the Off position, which is perpendicular to the direction the gas line is running
Remove the cover to boiler access panel
Locate the thermocouple, and take a picture of it with your cell phone or tablet
Remove the thermocouple by undoing the nuts at both ends
Connect the voltmeter to the wires extending from the thermocouple, and set the voltmeter to the proper millivolt setting
Hold the thermocouple with pliers, since it might get hot, ignite the lighter, and heat the thermocouple copper
If the voltmeter spikes, the thermocouple is working, and you can replace it using the picture as your guide; If it doesn’t, you’ve solved the issue: You need a thermocouple

2. Little or No Heat

Low water pressure is a common cause:

Check the pressure gauge on the boiler
If the pressure is too low, add water until the proper pressure registers on the gauge
Look for leaks at the system’s valves and connections that might be the cause of low pressure
If you find a leak or if the pressure drops again, call a service technician

3. The Boiler Cycles On and Off Frequently

When a boiler cycles on frequently, and your home is too cold or too warm, try these troubleshooting tips:

If the system is new, and the house is too hot, check to see if your home’s thermostat is installed on an outside wall, near a drafty window or by an entry door, and if any of those apply, it will have to be moved
If the system is new, and your house is too cold, your home’s thermostat might be installed in direct sunlight or near a heat source like the refrigerator or dryer and will have to be moved
When this is a new problem on an older boiler, increase the boiler’s upper-temperature limit, since it might not be making enough heat
If it doesn’t stop short-cycling, call a technician

4. No Heat in a Zone / Too Much Heat in a Zone

This is one of the easiest Weil McLain boiler troubleshooting issues to diagnose. Make sure the thermostat setting for each zone is where it should be, and if one zone is still too hot or cold, an electronic zone valve needs to be replaced.

5. Carbon Monoxide Alarm Triggered

The most common cause of leaking carbon monoxide is the plugging of the boiler heat exchanger fins with dirt and debris. If your CO alarm goes off, the safe approach is to open your home’s doors and a few windows to ventilate the area, evacuate the house, and call a boiler technician from outside. Here’s what the technician will do to check the heat exchanger:

Remove the boiler cover
With the aid of a flashlight or headlamp and a small mirror, the heat exchanger can be checked for debris or cracks
If dirt is the issue, the heat exchanger can be cleaned with a nylon brush and shop vacuum
If the heat exchanger is cracked, it’s an elephant sitting on the fence – It’s time for a new heat exchanger, and possibly for a new boiler

Caution Notes

Boilers present many significant dangers. Turn off power to the unit before opening the cover. This will eliminate the risk of shock. If you smell gas or oil fumes at any time, there’s a risk of explosion. Don’t ignite anything, and evacuate your household immediately. Call your utility company or emergency services from outside your home.

Finally, remember that carbon monoxide is deadly, so it’s important to have a detector near the boiler. If it sounds an alarm, turn off the boiler until you can inspect and repair it.

Rheem Water Heaters – Common Issues

Here’s a list of the most common Rheem water heater problems to look for. Solutions requiring multiple steps are found below.

No Hot Water

A tripped circuit breaker will shut down an electric heater and gas models that use electricity.

Gas: Check if the gas valve has been turned off. If you use propane, your tank might be empty. If the unit has a pilot light (see your manual), check to see if it is lit.
Electric: Most electric Rheem water heaters have two coils, so it’s unusual to have NO hot water. Check the circuit in the electrical box to make sure it hasn’t been tripped. If it is on, it’s possible the circuit breaker in the box has failed.

Not Enough Hot Water

If the water heater is new, or if you’ve just moved into a new home and aren’t familiar with the water heater’s capability, it’s likely that the unit is undersized. You’re using hot water faster than it can make it. This problem is more common with electric models since they don’t heat water as quickly as gas models.

Gas: If the burner is firing, but you’re not getting enough hot water, the unit is too small, the gas valve is plugged with debris from age or the temperature is set too low.
Electric: If this is a new problem, then one of the two heating elements or thermostats is probably bad.
Mineral deposits: There’s another reason for this issue, and it applies where very hard water is being used. Mineral deposits build up in a tank, so that within three to five years, especially if the tank isn’t periodically drained, mineral buildup can reduce capacity by up to 15 gallons.

There’s Water on the Floor

The water could be coming from a leaking tank, more common in old water heaters, a loose fitting or normal discharge from the temperature pressure T&P relief valve.

Tools You’ll Need for the Job

This small collection of items will assist you in Rheem water heater troubleshooting and possibly making a repair.

Your owner’s manual: There’s likely a section in the manual on Rheem water heater troubleshooting that will address the issue you’re having. If you don’t have the manual, you can probably find it online by searching the model name or number.
Flathead and Philips screwdrivers
Electrical tester
Pipe tape: Make sure it is for water and not gas.
Small plumber’s wrench
Bucket and towels
BBQ-style lighter
Heating element wrench (electric models only): An element wrench like this one can be purchased for $9-$15 at home improvement stores and online sellers.

Rheem Water Heater Troubleshooting

Here are tips for solving your Rheem water heater problem or deciding to call a Rheem service company to handle the repair.

No Hot Water

All electric water heaters and gas heaters that use electricity: The first issue to troubleshoot is a lack of power to the unit.

If the water from the hot tap goes cold, give a gas unit 15 minutes and an pressure relief valve 30 minutes to start making enough hot water for you to notice at the tap. However, if the water remains cold, it’s safe to say the unit isn’t heating water.
If the circuit breaker in your electrical panel is in the “Off” position, turn it to the “On” position. If it is midway between the two, it has been tripped. Turn it all the way to “Off”, and then turn it to the “On” position. If the circuit continues to trip, there’s an electrical issue that needs to be diagnosed and repaired by a qualified service technician.

Gas water heater: If your unit has a pilot light and it isn’t lit, follow the instructions in your user’s manual to relight the pilot using the BBQ lighter. If the unit has an electronic ignition and it won’t fire, the ignition might require replacing. Since replacing it involves the potential for a gas leak if not handled properly, consider calling a repair technician for the work.

Not Enough Hot Water

Gas water heater

If your gas water heater isn’t making enough hot water, try adjusting the thermostat to a higher setting. This might require a flat screwdriver placed in the slot on the adjuster. The manual has detailed instructions.

Caution: It’s recommended that you set the thermostat no higher than 120 degrees Fahrenheit to reduce the risk of severe burns from scalding. If the unit still doesn’t make enough hot water, it is either undersized for your needs, partially filled with mineral sediment or has a plugged gas valve. A Rheem technician can check the gas valve and clean or replace it.

Electric water heater

If you’re getting some hot water, and you can hear the unit heating, check the thermostat set point. Adjust it to a higher temperature, but no higher than 120F. If the water continues to be warm but not hot or heats very slowly, then one of the heating elements or thermostats is bad.

Use the electrical tester to test the heating elements and thermostats. Electrical current won’t pass through a bad part. Parts like this Rheem element and this Rheem thermostat are available online and at home improvement stores for less than $15. Titanium elements are available for about $50 if you want to reduce the chance of having to replace it again.

Replacing an Element/Thermostat

To replace an element or thermostat:

Turn off the double 240V circuit in the electrical panel for the water heater.
When replacing a heating element, shut off water leading to the water heater. Turn off the pump’s circuit, if you have a well and pump. Open a hot water faucet in a tub until the water stops flowing. This takes pressure off the water tank.
Remove the part from its packaging. Do the same with the wrench when replacing a heating element.
Use a screwdriver to disconnect the wires to the bad element or thermostat.
Place a couple towels on the floor if replacing an element. Quickly loosen the element with the wrench first and then with your hand. Pull it out quickly, insert the new element, and hand-tighten it. Then, use the wrench to tighten it until there are no leaks. Be careful not to overtighten it.
If replacing the thermostat, take a digital picture of the thermostat’s wiring before removing the wiring and the bad part. Install the new thermostat. Check the picture to ensure proper wiring.

Note: If you’d prefer not to have a small amount of water leak from the tank while replacing the element, drain the tank first by attaching a garden hose to the threaded spigot near the bottom of the tank, running the hose to a floor drain or to the outside of your home and turning on the spigot.

There’s Water on the Floor

If this problem starts immediately after you install or repair a water heater, a fitting is probably loose. Turn off power to the unit, if applicable, and check all pipe connections for water. Gently tighten any wet connection. The connection should have pipe tape on it and be very snug, not overly tight. If you replaced an electric element, remove the cover to it, and check/tighten the element if necessary.

In Case Everything Is Set

If everything is tight, the next step is to determine if the relief valve releases water.

Place a bucket on the floor beneath the valve or hang a light bucket from it, and if there is only water in the bucket the next time it leaks, you’ve found the source.
If the thermostat is set above 120F, turn it down to that temperature or lower. Having the thermostat set too high will cause water expansion and force water out the valve.

If Water Is Still Dripping

If water continues to drip or flow from the temperature/pressure relief valve, you can replace it with the following steps:

Purchase the right valve for your model. Your manual should have a parts list in it, or you can find one online. Common Rheem T&P valves like this one cost less than $20.
Turn off power and water to the unit, and turn off the well pump, if applicable.
Either run hot water at a tap for a few minutes or through a hose attached to the drain near the bottom of the tank. This should lower the water level to below the valve location.
Flip open the relief valve to take any remaining pressure off the tank.
Using a wrench, loosen the old valve by turning left/counter-clockwise.
Wrap pipe tape clockwise around the new valve’s threads, and install it, tightening by hand until snug.
Use the wrench to continue tightening it one-quarter to one-half of a turn
Turn the power and water back on. Allow the water to heat up. If the valve leaks because it is too loose, tighten it another quarter to half a turn.

If water isn’t coming from a fitting or the T&P relief valve, the tank is leaking. It’s probably time for a new water heater.

Caution Notes

We’ve included several safety steps in this Rheem water heater troubleshooting guide to prevent burn and shock. Here are additional warnings:

If you smell gas around a gas water heater, turn off the gas valve and don’t ignite anything. Evacuate your home, and call a repair technician or the gas company.
Since deadly carbon monoxide (CO) is a byproduct of the combustion of natural gas and propane, it is important to install a CO detector near a gas water heater. If the carbon monoxide detector goes off, evacuate the area. Call 911 or a service technician immediately.

Rheem Water Heater Troubleshooting Summary

If you didn’t find the issue you’re having here or these steps don’t solve it, a service technician can help. They can evaluate whether you can repair or replace your water heater. Replacement makes sense if the unit is 7+ years old and the repair is a costly one.

Pros and Cons of Bestech and Braeburn 1000 Thermostats

Here are the advantages and disadvantages of Bestech and Braeburn 1000 thermostats.

Pros:

These units have a price that competes with similar non-programmable, 1-stage and 2-stage thermostats from top brands like White-Rodgers, Emerson, and Honeywell;
Models are available to support up to two stages of heating and cooling including heat pumps;
All models have a fan-on mode, so you can turn on the fan to improve your home’s airflow and ventilation even when the system isn’t heating or cooling;
The thermostats have permanent memory to retain temperature settings following power outages
They work with natural gas, propane, oil and electric systems;
The warranties are good, especially the 5-year one when compared with Nest (1 year), Ecobee (3 years) and other thermostats that cost five to ten times as much;
Braeburn 1000 and Bestech thermostat models are easy to use;
The 3 square inch display on Economy models is large enough to read from a reasonable distance, especially with the bright LCD backlighting.

Cons:

There is no system compatibility checker as found on many thermostat manufacturer websites, so you must know how many stages of heating and cooling your HVAC system has to ensure you buy a compatible Braeburn 1000 / Bestech thermostat;
You must manually change the non-programmable thermostats every time you want to adjust the temperature. Thus, most likely you will not reduce energy and cost by turning the system down at night or when you’re leaving the house;
As very basic thermostats, they don’t track energy use or provide you with notifications of a need for maintenance or repair;
They don’t come with WiFi, so don’t allow for remote monitoring and control or integration with smart home systems;
All models require a C wire to have continuous power, so you’ll have to install one or use a spare wire if you don’t have a dedicated C wire in the wire bundle;
Builder-grade Braeburn 1000 thermostat and Bestech thermostat models have displays of just two inches square, so they can be difficult to read from a moderate distance.

Things to Consider Before Purchasing a Bestech Thermostat or Braeburn 1000 Thermostat

The first critical issue is to make sure the thermostat you select supports the number of heating and cooling stages your HVAC system offers. If you have a two-stage furnace, for example, and install a thermostat that only supports one stage, the furnace will run at full capacity all the time, costing you indoor comfort and energy savings. Information about your HVAC components is available in your owner’s manuals, on the manufacturer’s website or from the installer.

Secondly, consider the downside of a non-programmable thermostat. While the upside is affordability, you won’t enjoy energy savings if you forget to turn down the furnace or AC when you leave for the day. There’s a comfort factor too. If you do turn down the furnace when leaving, your home won’t be as warm as you’d like it to be again until you get home, turn the thermostat back up and wait for your house to warm. Programmable and WiFi thermostats help ensure the house is warm when you arrive.

When a Braeburn 1000 or Bestech Thermostat Is Right for You

These thermostats are affordable and get good marks for dependability. Luckily, those are the goals some people have for their thermostat purchase. In this case, Bestech and Braeburn 1000 thermostats will do the job. They make sense:

If your routine is very much the same from day to day. As such, you’re in the habit of turning the thermostat down to save energy;
For installation in part-time settings like a workshop or vacation home where you want basic thermostat functionality

Affordable thermostats like these remain popular even while smart thermostats get a lot more press. Did this Braeburn 1000 Series and Bestech thermostat guide help you make a buying decision? Please pass it along to social media to inform others!

Goodman Furnace Troubleshooting Basics – Common Problems and the Solutions

Before you troubleshoot a furnace, you should first understand how you work with potentially deadly voltage and highly flammable gas, and you do this at your own peril. If you can’t work on it safely, you shouldn’t attempt it because it wouldn’t be worth the danger. We first saw Goodman furnaces installed in the late 1980s to now, and they have 80 percent efficiency, but you occasionally have a need for Goodman furnace troubleshooting. The fan extracts burned gases from the heat exchanger and transfer it over to the vent.

Why You Might Need Goodman Furnace Troubleshooting

Understanding Goodman furnace troubleshooting and 80 percent of the failures can help you with your furnace. Before you call in the professionals, you might have some of the more common issues that will be easy for you to work on yourself. Even a need for a part shouldn’t discourage you because almost anyone can figure out some of the most common problems. It makes this easy to install, and you can normally buy this from one of the local suppliers. Here are some of the things that you should keep in mind with Goodman furnace troubleshooting issues:

Examine the settings on the thermostat.
Ensure the power works through the switch, breaker, fuse and indicator light.
Look at the filter.
The inline gas valve should be opened.
The flame sensor for the ignition confirmation.
Check for the blockage in the chimney and the pressure switch.
Know when to call in a professional technician.

Some of these things are simple things that you can do, but we don’t recommend that you do some of the more complicated tasks because this can be dangerous without the skilled knowledge of a professional.

Tools and Specs to Keep in Mind

The tools and specs you need will largely depend on the task at hand. For example, if you were to clean your furnace, you will need a toothbrush, vacuum, scrub brush, cotton swabs, toothpicks, rags and a replacement filter. An HVAC professional will have a lot more like:

Hammer;
Cordless drill;
Cordless saw;
Tape measure;
Bits;
Screwdrivers;
Wirecutters;
Pipe wrench;
Tool bag;
Utility knife;

While these are tools a professional uses, we never recommend the average person start drilling in the furnace without the proper knowledge or use a cordless saw because working with a furnace can be dangerous. Even without the dangers of high voltage, you want to make sure you work on it correctly because furnaces can pose a danger. In fact, more than 200 people die across the United States each year because of a problem with furnace ventilation in the home.

How to Check the Thermostat and Furnace

While it might sound goofy, you actually want to look at the thermostat for a couple telltale signs. You’d be surprised how many times an HVAC professional shows up only to replace the batteries in the thermostat. First, look for a jumbled digital display. If you have this, the thermostat might need replacing, and an HVAC professional can do this. You might also check the batteries or look at the temperature setting to make sure that it has been turned up high enough. You might also look inside for loose wires or wires that are touching. In some cases, you might need to tighten up the wires or tidy them up.

You can test your thermostat easily with a small to a medium-sized screwdriver, and you will use a short 18-gauge wire. To test the thermostat, you go to the furnace and remove the doors. Next, you will locate the circuit board, which is where the thermostat connects to your furnace. You should disconnect the wires from the “W” and the “R” terminals. In most cases, the wires will be red and white, but this isn’t always the case. You will connect the jumper wire between the R and W terminals. Next, secure the door of the furnace to see if it will work. If it works, the thermostat isn’t the problem. If it does work, then you likely have a malfunctioning thermostat that you need to replace.

You might also check for the power to and from the furnace. You should hear the furnace attempting to ignite. If you hear the blower running without the heat, then it isn’t a problem with the power, and you can likely skip checking the power. Otherwise, you will want to check the service switch of the furnace, and you will want to make sure the red light for the furnace circuit board has been turned on. If you don’t have power, then you should call an electrician because this is working with high voltage, which can be extraordinarily dangerous without specialized knowledge.

Caution Notes

When it comes to the furnace, an ounce of prevention is worth one pound of cure. Routine cleaning and maintenance on the furnace don’t demand specialized knowledge if you have a few hand tools, but we don’t recommend you do anything tricky or dangerous with the furnace. For example, don’t try to adjust the gas burners. It’s one of the most important aspects of the furnace, and you want to make sure that it has been set right because this distributes the gas in the furnace correctly. If it isn’t done correctly, it can cause a flash fire.

With Goodman furnace troubleshooting, the key is almost always prevention. We want to take measures that will extend the lifetime of your furnace. When in doubt, call an HVAC professional because they will have the right knowledge to do the work. We will always recommend you leave the dangerous stuff to the professionals, but you might look at the symptoms to help you with diagnosing a specific problem to decide if you need a professional. If you don’t feel confident in the steps shown, we recommend you skip them. Have you ever done Goodman furnace troubleshooting? If so, we’d love to hear your thoughts and experiences of it.
