Steps To Take If Your Electric Furnace Stops Working

Posted on: 9 March 2023

If you have a furnace in your home that is run by electricity, you likely value its performance during the cooler months of the year. If you suddenly discover your furnace does not turn on when it is needed, some troubleshooting is necessary to get it back into working order. Here are steps to take to attempt to repair your furnace so it works as it should.

Check The Thermostat First

If your thermostat is no longer working properly, your furnace will not come on when the temperature drops. Check that the monitor on your digital thermostat is still giving you a reading. If it is blank, it may need a new set of batteries. If this does not work, replace the thermostat before you try to troubleshoot the furnace itself. The thermostat may have worn out over time and it is a simple replacement that can save you money in the long run.

Make Sure The Igniter Switch Is Working

The igniter switch in your furnace is the portion that starts the flame so your furnace heats your home. If this fails to work properly, the furnace will shut down after a few attempts at lighting it. The igniter portion of your unit needs to be completely free of debris. Turn off your furnace and shut the main electricity via the circuit breaker that runs to the unit. Clean the igniter switch with a soft-bristled brush to remove any loose debris from this part. Turn on your electricity and the furnace once again. Turn up your thermostat to check if this process worked at fixing the problem.

Look At The Alert Lighting System

Most electric furnaces have a lighting system on the unit to let you know when a problem is occurring. The series of blinks that the lights emit is dependent upon the model of your furnace. If you no longer have the manual for your unit, check to see if it is available online. This will direct you to the portion of the furnace in need of attention. If you do not have experience with furnace repair work, or if you feel more at ease having a professional check on the unit, it is best that you contact a heating system repair service in your area. Give them the information regarding the lighting codes you have noticed on your furnace's panel so they can let you know whether there is a quick fix you can attempt on your own or if a service call is necessary.
