I just replaced the thermocouple in an old unvented wall heater because the pilot wouldn't stay lit. Now the pilot is fine, but new problem, the thermostat doesn't seem to be triggering the burner. So I figured I'd cut back the thermostat wire and see if that resolves the problem. The thing is, the thermostat wire seems embedded in the gas valve (36C06-101). Anyone seen anything like this and can advise what to try next? I'm stumped!

Here's the front:

And here's the side where the wire seems to be stuck in and I can't remove it:

Please help if you can. Thanks!

Yes, that's the thermostat wire, so no hole. Either way, if I can't remove the wire, I can't replace it. It's stuck in.

Hmm.... I say it's a hole because that's not a wire. It's the thermostat thermocouple and it can't be replaced. You need to replace the entire thermostat.

You're right, my bad. It's the gas valve thermocouple. Everything else stands as stated. The thermocouple contains an inert gas that, when heated expands against a diaphragm to open and close a set of contacts in the valve.

Ok, I replaced the pilot thermocouple, and I can't just replace the gas valve thermocouple? I'm not sure what part to get.

Sorry, I don't have anything to look up. It might be rebuildable. I don't know
