On the list of most severe inner thoughts in the world is having to speak to a HVAC system expert during the dead of the winter time on account of 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.
Perhaps the most common cause for a furnace not to do the job 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 your thermostat appears to be working OK but your furnace is not turning on at all, the circuit breaker could be tripped. 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.
You could have a filter that is full of dirt if your furnace turns on but does not seem to be blowing air. Make sure you change your filter immediately after every season. If you check your filter and find that it is dirty, change it right away.
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 possibly go out, and of course if it does, your central heat won’t 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.
An issue with your ignition sensor is a second good reason your furnace might not function. These units are regularly in contact with fire and could get burned around the ends. Your furnace may not turn on or may not stay on if that happens. It is possible to take out the sensor and use a wire 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.
