Among the worst emotions and thoughts on the globe is having to call a furnace professional from the dead of winter because your heat is not starting up. And there are some things you should check before you call a heater repair technician, because there are a number of reasons why your heater may not work.
An issue with your ignition sensor is an additional reason your furnace may not deliver the results. These devices are regularly exposed to flames and might get burnt off on the ends. If that happens, your furnace may not turn on or may not stay on. You could take off the sensor and use a scrub pad or part of sandpaper to remove the soot. If that doesn’t fix the problem, however, the sensor is probably bad and will need to be replaced by a professional.
If your furnace turns on but does not seem to be blowing air, you could have a filter that is full of dirt. You should replace your filter following each season. If you check your filter and find that it is dirty, change it right away.
If your thermostat appears to be working OK but your furnace is not turning on at all, the circuit breaker could be tripped. If necessary, this is an easy fix, as all you have to do is check the circuit for your furnace in your circuit box and reset it.
One common basis for a furnace not to perform is a problem with the thermostat. If your heater isn’t turning on, check to make sure your thermostat is set to “heat” rather than “cool.” If you have a programmable thermostat, check to make sure that there isn’t a time and date setting programmed in that is preventing the heater from coming on. If the problem is with your thermostat, it is an easy and relatively cheap fix, and that is good news.
If you have a gas furnace, there is a pilot light that ignites your gas burner to provide the heat for the unit. This light may go out, so if it does, your central heater is not going to blow hot air. You can easily check the pilot light and relight it if necessary. However, if you smell a strong odor of natural gas, you should call in a heater repair technician.
