Important Things to Check When Your Furnace Doesn't Work

Posted on: 5 December 2016

Have you fired up your furnace for the year, only to find that it isn't working the way it should? Are you hoping that the fix is something easy that you'll be able to do yourself? While many repairs are things that can only be handled by a professional, there are a few things that you can do while waiting for the repair technician to arrive. Some of these things include the following.

You can change the air filter. 

A clogged air filter can restrict airflow to the system, potentially causing overheating and other issues. By changing the filter regularly, you may be able to avoid making more heating repairs in the future. Make sure to only use the manufacturer recommended air filters. Using the incorrect size or type of filter could potentially be just as bad or even worse than not changing the filter at all. If you're having trouble locating the correct filters for your furnace system, your repair technician should be able to help direct you to where they can be purchased. Taking the old filter in to the store can be helpful as well.

You can check the flame. 

If your furnace unit has a flame that is easy to access or see, watch it when you attempt to turn on the furnace. Does the flame come on and immediately shut off? If it comes on, make a note of what color the flame is. The flames for a natural gas furnace should burn a clear blue color. Any other colors can be a sign that the burners are dirty or otherwise need to be adjusted by a professional. Perhaps it doesn't even come on at all. When the technician arrives to perform your heating repairs, he or she may find your information useful in helping to quickly locate the source of the trouble.

You can lubricate the blower motor. 

When the blower motor doesn't turn, it isn't blowing air and, thus, won't be able to heat your house. Without lubrication, the motor may seize and burn out, necessitating a call to a technician for heating repairs. Your owner's manual should give instructions on how and when to lubricate the motor. But if the house didn't come with an owner's manual when you bought it, you can either have a repair technician perform the task regularly or else show you how to do it so that you can do the job yourself.
