When the snow is falling and your furnace repair fails, it’s a “cold comfort” to know that the failure was most likely avoidable. The best way to avoid furnace repair failure and subsequent freezing is to check your furnace repair every year before the cold season arrives.
If you have a furnace repair problem, look through the list we’ve compiled below to hopefully save some time and money.
1) A defective thermostat:-
The first thing to look for is whether your thermostat is working properly. First and foremost, is it turned on? Is it in the proper setting? Check that it is set to heat. This may seem obvious, but a quarter of all service calls could be avoided with this simple check.
2) Breakers and switches:-
Second, is the furnace repair unit truly the source of the problem? Check your fuse box to see if any fuses have been blown. Check to ensure that none of your breakers are causing the furnace repair to fail. And make sure the power switch is turned on – every furnace repair has one!
It’s also a good idea to double-check that the front panel door is properly latched; if this door isn’t secure, most furnaces won’t turn on.
3) Failure to Ignite:-
If the above suggestions haven’t resolved the problem, check to see if it’s the ignition. Your furnace repair cannot function if the pilot light or electrical ignition systems malfunction.
Open the burner chamber door and locate the pilot light tube to test a pilot light. If there is no small flame, your pilot light is most likely out.
4) Blower Engine:-
If the blower motor (or fan motor) fails, the furnace repair will be unable to move the heat generated by the furnace repair through your home. Check to see if there is a problem with the fan motor, as this could indicate that your furnace repair is still working but not blowing warm air where it should.
