Common Furnace Problems That Can Arise And How To Repair It

The winter is cold and harsh enough outdoors without coming inside to find that your heat is out and it is as cold inside as it is outside. This is not a type of cold that can be fixed with an extra blanket. This is a cold caused by your furnace going out completely or working poorly. If you don’t know how your furnace is made, it can be hard to find the issue and fix your furnace on your own. There is, however, a checklist of sorts that you can keep handy that could help you identify the issues and make some of the repairs by yourself. Below is a list of common furnace issues and ways to fix them.

Make Sure Your Thermostat Is On

This may make you laugh a little, but the first thing you should do is check your furnace and make sure it is set to “heat” and that is is five degrees or more above room temperature.

Check The Thermostat Battery

If you have a battery run thermostat, you should change the batteries out at least once a year, sometimes more if you use it more often. Often times, your thermostat will flash a symbol indicating that you need to replace your batteries as soon as you can.

Get Rid Of Debris And Dust

Dust and debris often collect inside your furnace. More often than not, it does not collect enough dust to cause any harm. However, if you do not clean the dust and grime out of your furnace at least once a year it can clog up and cause the heat to not be able to blow out well and produce enough heat. You may have to change the filter all together which is an inexpensive part that you can buy at a hardware store. If you replace the filter, make sure you put it in the correct direction or else its effectiveness may be reduced.

What To Do If It Is Not Producing Heat

If the furnace is not producing heat there could be a couple of different causes. The first thing to do is check the circuit breaker to see if a fuse may have been blown or just tripped. You can reset the breaker by flipping it back and forth in the on-off position. This may fix the problem, but if it doesn’t you may need a new circuit breaker installed or have a technician check the wiring in the circuit.

Check The Furnace Door’s Safety Switch

If your furnace will not turn on, the problem may be as simple as the safety switch popping out from when the door was opened. When this switch is flipped it does not allow the fan or the burner to turn on. Check to make sure the door and the switch are in place so that the furnace will operate effectively. If you find that you need a new safety switch all together, you can call a technician who will come test the wires and install a new switch for you.
