Troubleshooting an electric furnace can take place only if you are handy for that. Start with the obvious and move to the complex components. Verify the unit has power. Sometimes a power outage can cause your electric furnace to malfunction. If there is a reset button on your electric furnace, try resetting the furnace following the manufacturer's instructions. If that doesn't work, begin your troubleshooting diagnosis by starting with the thermostat. Set the thermostat at least 3 to 5 degrees above the room temperature in the heat setting. Wait for the furnace to come on to check for heat. For mechanical thermostats, verify the fan switch is on before checking for heat. Digital thermostats often use batteries for power. Check the batteries and replace them if they are no longer functional. Verify the fan is operational. While the heater may work, if the fan or blower motor are not functional, the furnace won't effectively distribute the warm air throughout the house. Confirm that the fan is set to the "on" or "auto" position on the thermostat. If you have verified the unit has power and the thermostat works, but the fan does not come on, the fan relay might be broken. If the fan stays on without heat, check the thermostat setting. When the fan is set to "on" it stays on until you shut it off. Set the fan switch to "auto" to have it cycle with the heat. Verify the blower motor's belt is not frayed, worn or broken. When the belt is too loose it causes the blower motor to malfunction. Remember to take care of your furnace in advance to make sure your home will be warm in winter.
