Among the many most unfortunate thoughts on this planet is having to phone a heating system specialist during the dead of the winter months on account of your heating is not switching on. There are a number of reasons why your heater may not work, and there are some things you should check before you call a heater repair technician.
A problem with your ignition sensor is one other good reason your furnace might not exactly perform. These units are continually exposed to flames and may also get used up around 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 component of sandpaper to reduce 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. It is best to replace your filter right after just about every season. If you check your filter and find that it is dirty, change it right away.
The circuit breaker could be tripped if your thermostat appears to be working OK but your furnace is not turning on at all. 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.
A common cause of a furnace not to function is a problem with the thermostat. Check to make sure your thermostat is set to “heat” rather than “cool” if your heater isn’t turning on. 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, and if it actually does, your heater cannot blow hot air. If necessary, you can easily check the pilot light and relight it. However, if you smell a strong odor of natural gas, you should call in a heater repair technician.
