I have a 1964 Heat Wave pin. I have just being playing it and the thing that measures the temperature isn’t resetting itself (it’s stuck on tirrid). I don’t know what to do. Shall I just carry on or is it a problem?
Ok thank you.I think this is a fault. This Pinsider had the same issue - ended up being a broken wire for them, could be different for you but the good thing with that thread is it has images from the schematic and a few troubleshooting tests to try.

Good luck!
