Any ideas I can try to fix it myself?


Thanks!
I had the exact problem on our first trip out in our 28A. About a half a tank of hot water and then nothing on LP or AC. Turns out there is a thermocouple that is between the power and thermostat accessed from the outside of the coach. If there is an issue with the propane coming back it heats up and disconnects the WH.

I ordered two sets just so I could have enough spares.
BTW I don't know why they include the extra connecting wire. I didn't use it.
