How do you fix a wall heater?
- Check the thermostat to make sure it is turned high enough if the wall heater is not coming on.
- Turn the breaker off and remove the cover of the wall heater by removing the screws with a screwdriver and pulling the cover off.
- Remove the wire on the thermostat that leads to the heat element.
Also question is, why is my wall heater not working?
If your heater's not working at all, check for a tripped breaker or blown fuse. You'll need to shut off the power to the heater and remove it from the wall in order to check the wiring connections. Remove the heater control knob, thermostat knob and faceplate to check for loose connections in these mechanisms.
In this way, how do wall heaters work?
Gas heaters are installed directly on the walls, allowing for free-flowing heat. Gas heaters are lit from the bottom using a pilot light. The heating element is heated through the electrical current, and heat is expelled into your living space via the wall unit.
If a clanging or knocking noise occurs only when your furnace first starts or right after it stops blowing hot air, the sound probably is caused by expansion and contraction. The metal housing, vents, pipes and other parts make clanging and banging noises as they heat up and cool down.
