Tackle Common Furnace Problems With Troubleshooting Tips

Tackle Common Furnace Problems With Troubleshooting Tips

A cold Indianapolis winter requires a furnace that works whenever you need it. When you have furnace problems, however, there are some troubleshooting steps you can take that may get the system working again before you have to call for repair.

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