Tank monitor dead, no water heater, no power zone 1 and 3
I have a Sunset Trail 336BH. For a while, the water heater only worked on electric. I bought a new circuit board, installed it, and neither gas or electric worked. Put the old one back in, electric worked. The next time I used the trailer, I got no hot water on electric. Fuse was blown on the board. Replace with a 5amp bc the parts house didn’t have a 2amp, electric water heater worked. This weekend, no hot water again. Tried using the new one I bought, fuse blew. Put the old one back in, and all of the sudden no lights when the switch for electric or gas was flipped. Also, the lights for the tank monitor didn’t light up.
I checked breakers, and fuses. I even pulled fuses to check them, but I noticed on zone 1 and zone 3 fuses, once pulled there wasn’t a red light that came one that would indicated a broken circuit (from no fuse or blown fuse). The water pump switch still lights up on the panel, and all the lights work, slides, awning, etc on the panel. The AC works, as well as the furnace. The furnace has been acting strange lately though, but I don’t know if it’s related. I was having an issue occasionally that the furnace would kick on when activated, run a couple cycles and never come back on unless I turned the climate control to off, waited to hear a click, then turn the heater back on. Again, it would cycle 2 or 3 times and never come back on. I did the mysterious breaker trick on the actual furnace, and it worked fine again for weeks.
What am I not getting here? Possible loose ground somewhere??
