How To Troubleshoot
Furnace Issues

Some common problems with furnaces can be resolved quickly. Before you reach for the phone to call for help, try these furnace troubleshooting tips first!

#1. Check Your Thermostat:

Double check that your thermostat is set in the ‘heat’ position, and that the temperature setting is set for 3-5 degrees above the current temperature in your home. If your thermostat has a furnace fan, switch it to the ‘on’ position. Listen to see if your furnace kicks on. If you cannot hear it, check a supply register to see if you feel air coming through it. If your thermostat is an older model, check the batteries to make sure they work.

#2. Check Your Breaker:

Locate the breaker assigned to your heating system and move them to the ‘off’ position to reset. Wait a minute or two before resetting to the ‘on’ position.

#3. Double Check Power Switches to the Unit:

Your heating system may be equipped with an emergency shut-off valve. If your system has one make sure it is turned on. In most homes, the emergency shut-off switch looks just like a regular light switch and will be located on the side or close to the furnace.

Some heating systems also have emergency cut-out switches that are activated when a door or service panel is removed. Often the furnace door is not replaced properly after a filter cleaning and the cut-out switch will prevent the furnace from coming on. Check to make sure all access doors are properly secured and fitted.
