This may sound like a silly question but, I've owned by RV for over three years and always had to turn on the propane switch to get hot water. I brought it in to a repair shop a couple of years ago and they change the heat element and flushed the system, but it didn't help.
Yesterday, when I found myself out of propane and no heat I opened the access to the water heater and noticed an on/off switch which was switched off. By chance, is this the switch that turns of 110 v to the heater? It has been in that position since I had the work done.
I also have an on/of toggle inside the coach for 110 and propane and that 110V switch has been on.
By the way, my coach is a 38' 1998 Newmar Dutchstar.
I feel like a dunce right now.
