I have a univeral 40,000 BTU heater, New thermo coupler. new igniter. but wont stay running when thermo button is released. have to tape thermo button , to keep running. Dont like that!!
Is the sensor for the thermocouple located in the right spot in the flame,remove it and if you have access to a propane torch,heat the end till its red hot and leave it connected to the gas valve,then start the unit and this will tell you if the sensor is properly positioned in the pilot flame on the unit itself,if not you could have a defective new thermocouple or another safety device keeping it from staying lit or the gas valve is faulty
On the ridged heater. That won’t stay lit 5 minute fix and you have your heater again. Email me your number and I’ll call you and tell you how to fix it in 5 minutes. For 4cents [email protected]

It sounds like the gas valve itself is the issue. Typically you’ll have this issue when the pilot safety mechanism inside the valve fails. I would try another thermocouple before I relaxed the valve, as I have had them faulty out of the box. Good luck ??
