  • You might try to reestablish the air head before you replace the thermostat. However, I agree that it certainly sounds like it is defective.
  • I will third the thermostat. They are relativily easy to change. The kit will come with a new t-stat and an ECO ( emergency cut off )
  • I'll second the bad thermostat. There are You-Tube videos on how to troubleshoot but you will need to know manufacture and model.
