My cadet wall heater wont turn off

My cadet heater was doing this so I pulled it off of the wall and saw that the two wires coming from the thermostat portion had melted out of their insulation and were crossed. The heat is of some concern, but for now I just wrapped them in electrical tape to insulate them better against melting

I have a Dayton 3E366B hanging my garage, and it starts up -lights the burners - the fan kicks on, and then it shuts off... This cycle goes on and it does not run for long times to really get the heat up....

No I do not believe it is your thermocouple, as that only detects heat from the pilot light and permits the gas valve to open and have main flame ignition. I would be looking at thermostat placement, and safety limits built in to the heater. Making sure that the thermostat is not getting a straight on blast of hot air from the heater is my first guess. Try jumping out the thermostat by first removing the thermostat from it's housing and placing a jumper between the red and white wires as they are usually the control for heat. If your heater stays running it is the thermostat. If not you now have to trouble shoot all safety limits one at a time with a volt ohm meter and run continuity tests the limits should read closed except for the fan high limit it should read open until the temperature of the heat exchanger reaches it's set temperature. Remember to power down your unit when trouble shooting please.

Heater won't turn off. Wires were troubled

Shut off the gas to the heater. Bad gas valve. Gas should not be leaking from any part of the gas valve.
