Troubleshoot a Furnace Problem

If the heating system in your home stops working, don’t panic. Take a few minutes to troubleshoot the furnace problem and see if you can resolve the issue yourself. Sometimes, there’s a quick and easy fix to get the warm air flowing again, but other times it’s best to call in a professional heating technician.

Replace the Furnace Filter
A clogged air filter is one of the most common causes of furnace problems. A dirty filter can restrict airflow and cause uneven heating, inefficient operation or cause the system to overheat and shut down. Before calling for furnace repair, check the filter to ensure it’s not clogged and that it’s correctly installed.

Check Thermostat
It’s not uncommon for thermostat settings to get accidentally changed. Before calling a service technician, check the settings on the thermostat—make sure it’s set to HEAT and that the temperature is set above the current temperature in the home. You might also want to check the batteries to ensure they’re working correctly in the thermostat.

Secure Front Panel
A safety mechanism built into many furnace systems has to do with the front access panel. If it’s not completely closed or secured, the furnace might not turn on. Follow manufacturer instructions to ensure the panel is closed and secured.

If the above furnace problem fixes didn’t help, it’s time to call a professional service technician. We never advise homeowners to try any kind of furnace troubleshooting that involves opening the furnace as it can be dangerous and cause even more damage to the heating system.
