Boiler Not Heating Up? Ways To Attempt To Fix The Problem Yourself

No one wants their heating source to stop working in the dead of winter. Unfortunately, this is a situation many people face. If your boiler has stopped heating up, your home may be cold and you may be looking for a fast fix. Fortunately, there are a few things that can occur that are relatively easy to fix that would cause your boiler to stop producing heat. Here's how to try to solve the problem yourself.

Make Sure The Boiler Is Connected To A Properly Working Outlet

If your boiler is not working, one of the first things you should do is make sure that the boiler is connected to a properly working electrical outlet. You may have popped the circuit breaker or blown a fuse, both of which can make the outlet not function.

Try unplugging your boiler and plugging something else into the outlet. If the other item works when connected to the power source, your outlet is not the issue. If the other item doesn't work, the outlet is your issue.

Troubleshoot Your Thermostat

One of the main reasons any type of heating device doesn't appear to be working is because of issues with the thermostat, not the heating element itself. If your boiler isn't heating up, take the time to check your thermostat. Make sure that the thermostat is set on "heat" and the appropriate temperature. Your spouse or child may have adjusted it without you knowing.

If the settings are correct, check to see if the battery in the thermostat is working. If the battery is dead, your thermostat may also be dead, and your boiler will not know to come on.

Verify That The Gas Valve Connected To The Boiler Burner Is Open

If you have a gas or propane boiler, it is recommended that you close the valve connecting this power source to your boiler during the months that the boiler is not in use. However, before you use your boiler in the fall or winter months, you need to open this valve back on. This is something that many people either forget about or don't realize if they have just moved into a new home with one of these boilers.

If you are using your boiler for the first time this season, and it isn't turning on, check this valve. The valve is typically located on the bottom half of the boiler, on the opposite side of the expansion tank and drain valve. Turn the knob on the valve to allow gas or propane to flow and heat your boiler.

Check The Boiler's Water Level

If you still haven't solved your boiler problems, you should check the water level in your boiler. The water level in this heating device should be kept at about half-full. In a properly functioning boiler, your automatic filling system will ensure that the water level is kept at the appropriate depth. However, if the filling system isn't working properly, water levels will be low.

You will know water levels are low because the pressure gauge on the front of your boiler will read less than 12-15 psi. If you notice this, allow the boiler to completely cool and then turn the water feed valve until you hear water flowing into your unit. (Always allow the boiler to cool before adding water or you could cause the boiler to crack, or worse, explode.) Watch the pressure gauge and turn off the water when the gauge reads 12-15 psi. The water feed valve is located on the top of the furnace. It is important to note that you need to call a professional in to solve the automatic filling system problem, but manually adding water will buy you time and keep you warm until you are able to do this.

Unfortunately, there are many reasons why a boiler may stop producing heat. Some of these problems you can fix yourself, like a problematic thermostat or low water levels in your boiler. However, other issues, such as problems with the electronic ignition system or bad gas or propane valves, require the assistance of a professional. If you are unable to fix the problem using the above tips, consider contacting a heating repair company like Lowry Services: Electric, Plumbing, Heating & Cooling. A professional can evaluate your boiler and determine if the problem can be fixed or if you need a new boiler.
