Help with Troubleshooting an Electric Furnace

There will be times that you might need to call in a professional to help fix your electric furnace, but there are also some simple fixes you can do yourself. Every homeowner will be able to use these quick fixes to get their electric furnace working properly again.

Is your furnace getting enough heat?

Check to see if the furnace switch or the main breaker is open. If the fuse or breaker trips when you reset it, you need to call a professional to look at it.

It may be that the thermostat is set too low for the furnace to turn on; you will want to raise the thermostat setting to 5 ̊to fix this problem.

Check the filter, it may need to be replaced if it is damaged or you can clean the filter if it's just dirty.

Check to see if the blower belt is loose or broken. You will need to adjust the belt or simply replace it.

Check to see if you have a clogged filter or duct, just clean out the blower assembly to fix this minor problem.

The furnace won't run at all

If your furnace won't run at all the possible cause could be no power. If this is the case then you will want to check to see if there are any tripped circuit breakers or blown fuses at the main entrance panel. Also check the separate entrance panel, and on or in the furnace. Then you will need to restore the circuit to fix the problem.

Another reason for the furnace not running is there may be a motor overload. You will want to wait approximately 30 minutes, and then press the reset button. You may have to repeat the process if necessary.

The furnace is cycling on and off repeatedly

The furnace may have a clogged blower causing the furnace to overheat; you will need to clean the blower assembly. If the blower and motor have oil ports, you will need to lubricate the blower and motor to get the furnace working properly again.

If the filter is dirty, just simply clean or replace it.

The blower will not stop running

If the blower control is set wrong, you will need to reset the thermostat from the on position to the auto position. While checking the blower and you find that the relays are faulty, the best thing to do for this problem is call a professional to fix it.

These are some quick, simple fixes you can do to get your electric furnace working properly again.
