GMC wall heater common replacement parts

  • Control thermostat. The control thermostat senses room temperature and cycles the heater on and off to maintain the set temperature in the room.
  • Power cord. The power cord supplies electrical current to the heater switch and other electrical components in the heater.
  • Fan motor. The fan motor spins the fan blade to circulate hot air through the room.
  • Power switch. The power switch turns the heater on and off and supplies electrical current to the thermostat to control heating.
