It will soon be time to start your furnace again for the winter season. If you encounter furnace problems while testing your heating system this year, try these troubleshooting techniques to see if one or more can help get the furnace working properly again.
- No power: Make sure the furnace is connected to electrical power and is receiving electricity. Check the power switch on the furnace itself to make sure it’s on. Look at the circuit breaker panel to determine if the breaker controlling the furnace has been tripped. Reset the breaker and see if that starts the furnace again. If the breaker keeps tripping, call for professional assistance.
- Won’t start: Check the thermostat to make sure it’s on and functional. Change thermostat batteries if necessary. Make sure the pilot light is lit (for fuel-burning models) or that the electronic ignition is functioning properly. Ensure the furnace is receiving fuel and that storage tanks (for oil-burning models) contain fuel.
- No heat: Make sure the temperature settings at the thermostat are set to an appropriate level for the season. Move the temperature settings up a few degrees to see if that starts the furnace. Check that the thermostat is set to provide heating. An error at the thermostat could have turned off the heating function.
- No airflow: Check the air filter to make sure it is not clogged or overly dirty. As a rule, you should put in fresh, clean filters at the beginning of heating season. Clogged filters will interfere with system airflow and can cause malfunctions. Look for supply vents and air return registers that are blocked by furniture, boxes, clothing or other objects that could interfere with airflow. Make sure vents are open and that any dampers at the vents have not been closed.
