How To Diagnose Electric Furnace Blower Issues

Shannon Obrien

When the colder weather comes, you want your electric furnace to function properly.  Most furnace problems develop from the furnace blower, the part that transports heat through the vents, which may cause the unit to not start. It usually doesn't require a professional to diagnose problems with the blower. Follow these tips to diagnose electric furnace blower problems:

Inspect the Thermostat

Sometimes, the issue isn't with the blower itself, but other furnace parts. Set the temperature three to five degrees higher than the room temperature, and wait several minutes. Most electric furnaces are pre-set to activate at a certain temperature. 

If the temperature setting isn't the issue, check to make certain it is set on "Heat" mode and set the unit on "Fan" or "Auto". The fan will keep running in "On" mode, even when the heat is off.

If it still doesn't work properly, shut off the power from the breaker, and detach the thermostat. Inspect the wires for damage. Otherwise, wrap the red and white wiring together, and try the unit again. 

Also, look at the thermostat for dirt and replace the battery. If the thermostat still fails, replace it.

Reset Breakers or Replace Fuses

If you had electrical work done, the electrician may have turned off the breaker, or it could trip during a storm or power outage. Open the service panel by detaching the screws with a screwdriver, and look for breakers in the 'off' position or that have moved to the middle.

 Older homes may have fuse boxes. Fuses with broken metal lines or cloudy fuses indicate they need replacing.

Check Filters and Ducts

Air ducts often get clogged with debris or damaged, which may prevent heat flow. Feel the ductwork for heat and cracks.  

Find the cold air return, and examine the filters for dirt and damage, remove dirty filters, and clean them with a damp rag. Ensure the filter arrow points in direction of the vents.

Examine the Blower

The door to the furnace should be closed. The furnace door activates a switch, and when it is open, it prohibits the unit from starting. Shut off the unit from the breaker box or fuse box, and look for the furnace blower panel cover, which is commonly beside the furnace. 

Open the panel, and examine the blower belt for damage, and replace a damaged belts slides, or slide the belt back on track. Carefully touch the blower motor to see if it is hot, find, a yellow or red button, and push the button to reset it. 

Also, inspect the blower relay board, and look for recording. If you don't see a recording or the reading is not between 24-28, replace the fuse. In most cases. the whole control board needs replacing by a heating service.
