Tackle Common Furnace Problems with Our Troubleshooting Tips

A cold Dallas winter requires a furnace that always works when you need it. However, when furnace problems occur there are some troubleshooting steps to follow that may get the system working again before you have to call for repair.

  • Check the power: Check all of power switches and electrical connections to make sure they are turned on and working properly. Also, make sure the circuit breaker for the furnace hasn’t been tripped. Reset the breaker then to see if this turns the furnace back on. Repeated tripping of the breaker might signal a serious electrical problem that needs professional attention.
  • Check the thermostat: Make sure the thermostat is set to a temperature that’s seasonally appropriate and higher than your current room temperature. Move the settings up or down a few degrees to see if this kicks the furnace on. If your thermostat is a programmable model, also check that it is set to the “heating” function and that it’s receiving power. Change the batteries if needed.
  • Check the pilot light: Older heating systems could have a pilot light that provides ignition for the fuel the furnace uses. The pilot light should be lit and if it is not, re-light it (or call a professional to help do this). If your furnace has an electronic ignition, make sure the unit is working properly.
  • Check fuel supplies: Make sure your fuel-burning furnace is receiving fuel, either from its local utility connection if it’s a gas furnace or from the fuel storage tank if it’s an oil furnace. Additionally, make sure the utility gas supply is on and there is fuel in your oil tank. Check valves, fuel lines and related parts to ensure fuel is flowing to the furnace.
  • Check air filters: Make sure the air filters aren’t dirty and interfering with airflow. Put in fresh, clean filters.
