One of many most detrimental thoughts on the earth is having to call a heater expert within the dead of wintertime on account of your heat is not activating. 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.
A problem with your ignition sensor is one other purpose your furnace might not function. These units are consistently in contact with fire and might get burned on the ends. Your furnace may not turn on or may not stay on if that happens. You could take off the sensor and use a brillo pad or bit of sandpaper to eradicate 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 must replace your filter after almost 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. 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 if necessary.
Perhaps the most common reason for a furnace not to function is an issue with the thermostat. If your heater isn’t turning on, check to make sure your thermostat is set to “heat” rather than “cool.” Check to make sure that there isn’t a time and date setting programmed in that is preventing the heater from coming on if you have a programmable thermostat. The good news is that if the problem is with your thermostat, it is an easy and relatively cheap fix.
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 whenever it really does, your furnace will never 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.
