Furnace Not Working? It Could Be One Of These 4 Reasons
Have you noticed that your furnace is not working right and your home is feeling cold? If so, you're likely wondering what is wrong with your furnace so that it can be repaired. Here are some reasons why this problem may be happening to you.
The Furnace Is Overheating
One of the reasons why your furnace may be blowing cold air is because it is actually overheating. Modern furnaces are designed to keep the blower motor running if the unit is overheating as a way to cool it down. You'll obviously want to get to the bottom of why the unit is getting too hot by scheduling a service call as soon as possible, especially if the unit has been overheating a lot.
The Furnace Has Low Gas Pressure
If the furnace is receiving low gas pressure, it can't get hot enough to warm up your home. This can be a problem when extremely cold weather hits and your gas company can't keep up with the demand of everyone using their furnaces for so long at the same time. Gas pressure is going to be low, and the furnace won't be able to get as hot as it can. Since this is a problem with the gas provider, it means that nothing is actually wrong with the furnace and the problem must be worked out with the energy provider.
The Blower Motor Is Broken
If the furnace is turning on and you are not feeling air come out of the ductwork, it can be a problem with a broken blower motor. If something happens where that motor burns out, there will be no way for the hot air to be pushed out to your home. You'll need to have the blower motor repaired in order to get the air flowing again.
The Burner Is Dirty
Many older furnaces depend on a pilot light, which is a flame that lights the gas when the furnace turns on. However, this has been replaced with things like electronic ignition technology with hot surface igniters and things that do the job of a pilot light much better. However, that furnace with a pilot light can fail by getting too dirty. If there is soot on the burner, the pilot light may not work and allow it to ignite the gas, causing your furnace to stop working. Thankfully, a dirty burner is easy to repair.
