Some electric heater repairs require no experience. The first place to look is the thermostat, which often has a "reset" switch that can fix many problems. If the thermostat still fails to work properly, replacement is fairly simple.
Users can also set the furnace to "fan" mode. If the fan still ceases to turn, the fan should be inspected for obstructions. Next, its motor and run capacitor should be inspected for signs of damage. If the fan runs but the system produces no heat, an expert might need to be called in. Heating elements on electric furnaces carry a significant amount of electricity, and small mistakes can lead to severe burns and even electrocution.
