Learn 5 DIY Tips to Troubleshoot Furnace Problems

  1. Game “on”—it’s more common than you might think, but one switch in the wrong position makes all the difference between cold and cozy. Check that the furnace switch itself and electrical breakers are on.
  2. Check your ‘statthermostat, that is. Make sure it’s set to “heat” and that the setting is at least five degrees higher than the current indoor temperature to try to get the furnace to kick in. For programmable controls, make sure the day and time are correct for scheduled heating. If power has been lost, the thermostat may need to be reprogrammed. In addition, if your thermostat utilizes batteries, check them and replace if needed.
  3. Change your filter— Check to make sure your filter is clean. A dirty filter may cause the unit to shut down, so replace it and restart your furnace.
  4. Shut the front door—if the door on the front of your furnace isn’t closed properly, there’s a safety feature that prevents the blower motor from running.
  5. Go with the flow—condensation is normal but check to verify that your drain hose is clear and unobstructed.
