Among the most unfortunate thoughts worldwide is having to call a furnace expert from the dead of the winter months as your heat is not turning on. 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 an additional rationale your furnace may well not deliver the results. These products are regularly confronted with flame and may get burned up on the ends. Your furnace may not turn on or may not stay on if that happens. You may remove the sensor and use a brillo pad or section of sandpaper to take out the soot. If that doesnt 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 might want to replace your filter soon after every single 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. 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.
One common reason behind a furnace to not 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 isnt turning on. If you have a programmable thermostat, check to make sure that there isnt 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 be out, and when it really does, your central heater is not going to blow warm 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.
