Do Some Simple Checks Before Calling Your Furnace Repair Technician

While most furnace repair work should be performed by a professional, there are some simple fixes that you may be able to do yourself. For example, if your furnace is not getting enough heat, check that the main breaker is open and the furnace switch is on. But if the breaker or fuse trips after you have reset it, call a professional furnace technician.

Here are some other minor checks that you can do:

• Check the filter. If it’s dirty, you can clean it or replace it, and if it’s damaged, you can replace it.
• Check if the blower belt is broken or loose. If it’s loose, a simple adjustment may do the trick, and if it’s broken, you can replace it.
• If the ducts are clogged, clean out the blower assembly. This too is a simple furnace repair job.

The Furnace Doesn’t Run At All

A possible cause is no power. If so, you’ll need to check for any blown fuses or tripped circuit breakers on the main entrance panel. Check the separate entrance panel also, and in or on the furnace. A motor overload could be another reason why your furnace doesn’t run. Wait for about 30 minutes, and then press the reset button.

The Blower Won’t Stop Running

If the blower control is incorrectly set, reset the thermostat from the “on” position to the “auto” position. If you discover that the relays are not working properly while checking the blower, this problem must be attended to by an experienced furnace repair technician.
