Caleb with One Hour Heating and Air Conditioning in Lee’s Summit, Missouri gives several possible reasons why your furnace not working.
If your furnace is not heating, here are some reasons why:
- Check your thermostat first. Are the batteries dead? Is your thermostat set to heat?
- Do you have a dirty filter? If you have not changed your furnace filter recently, that could cause your furnace to malfunction.
- A common furnace problem is a dirty flame sensor, which will cause your furnace to not heat. It is a security feature for your furnace. This is easily prevented with routine maintenance.
Watch the video below for more reasons including two stories of very uncommon reasons why a furnace may not work.
