23 Jan Tackle Common Furnace Problems with These Great Troubleshooting Tips
A cold Houston winter requires a furnace that always works when you need it. However, when furnace problems happen follow these troubleshooting steps that may get the system working again before you have to call for repair.
- Check the power: Check the power switches and electrical connections to make sure they are turned on and working right. Also, make sure the furnace circuit breaker hasn’t been tripped. Reset the breaker to see if this turns the furnace back on. Repeated tripping of the breaker could indicate a serious electrical problem that needs professional attention.
- Check the thermostat: The thermostat should be turned to a temperature that’s seasonally appropriate and higher than the room temperature. Change the settings a few degrees to see if this kicks the furnace on. If you have a programmable thermostat model, check that it’s set to the “heating” function and that it’s receiving power. Also, change the batteries if they require it.
- Check the pilot light: Sometimes older furnace systems have a pilot light that provides ignition for the fuel the furnace uses. The pilot light must be lit and if it’s not lit, re-light it (or get a professional to help do this). If your furnace has an electronic ignition, be sure to check that the unit is working properly.
- Check fuel supplies: Ensure your fuel-burning furnace is receiving fuel, either from its local utility connection if a gas furnace or from the fuel storage tank if an oil furnace. Also make sure the utility gas supply is on and there is fuel in your oil tank. Check valves, fuel lines and other related parts to check that fuel is flowing to the furnace.
- Check air filters: Make sure the air filters are clean and dirt is not interfering with airflow. Put in fresh, clean filters.
