Answer:

If it continues to heat even with the thermostat disconnected then the board is defective on the unit and will have to be replaced. You should try to disconnect the thermostat to rule out a thermostat issue, but if it does not stop running and heating the board will need to be changed out.

All I ask is please use the Star Rating Link at the top of your page before leaving, that is the only way I am credited through the site, tips are appreciated.
