The solution is to turn the outside on/off switch to off. That shuts off all power to the water heater. Open the outside cover and that switch is on the left. Or you can turn the main coach battery on/off switch to off.

Now this could make a LOT of sense! It was relatively cold, temps in the mid 30s but those little white flakes dropping out of the sky off and on. Yes, it did seem like the unit was trying to kick in but couldn't. I remember asking DH if propane was on or off and he said it was off.

I'm a bit confused about the "outside" on/off switch. Is there a second switch we haven't learned about yet? The power on/off that DH was pushing is located on a panel inside the coach, in the bathroom.

Thanks so much for adding valuable info to our knowledge bank.
