Electric Furnace Troubleshooting Basics

Troubleshooting an electric furnace is a complicated process. If your furnace is experiencing problems, your Marietta HVAC repairs professional may be able to help, but there are a few things you can do on your own first. Ensure that your unit has power and try resetting it based off of your manufacturer’s instructions. If that does not work, there are a few ways to troubleshoot the unit.

Thermostat

To diagnose problems with your electric furnace, you should first ensure that your thermostat is operating properly. Set it to about five degrees above the temperature of the room, and then wait for your furnace to start. Check for heat, and if your thermostat isn’t working, ensure that the batteries inside of it are functioning properly.

Circuit Breakers and Fuses

Ensure that your circuit breaker for the furnace is on, as a power surge or electrical outage may cause a fuse to blow. Turn off the circuit breaker before turning it back on to check its functionality. Replace any broken fuses in order to restore power to your furnace.

Fan

In some cases your heater may work, but the blower motor or fan may not be functional. This will result in a furnace that doesn’t effectively distribute heated air throughout your home. Make sure the fan is set to on, and if it is but the fan still doesn’t turn on, this could be a sign that the relay is broken. Ensure that the motor belt to the blower isn’t broken, worn, or frayed, as a belt that is too loose may cause the fan to malfunction.

Dirt

A dirty electrical furnace will not work efficiently. If the air filter is dirty or clogged, the ability of the furnace to heat air will be impeded. Be sure that clogged or dirty filters are replaced, but before doing so, be sure that the power to the furnace unit is turned off.
