Nautilus space 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.

What to do when your Nautilus space heater won't power up

  • Check the house circuit for the heater to see if the house circuit breaker tripped. Reset the house circuit breaker to restore power to the heater if you found the house circuit breaker tripped.
  • Check the thermostat temperature setting and adjust the thermostat setting if the thermostat is set too low to turn the heater on.
  • Some heaters have a thermal overload switch that shuts off the heater if the heater draws too much electrical current due to a short circuit in wiring or a heater component. Reset the thermal overload and see if the heater works.
  • If the thermal overload keeps tripping, unplug the heater and check for damaged wiring or a broken heating element.
