Water Heater noise and odd wiring
Picked up our new coach last week. 2017, first owner, brand new, all that good stuff.
Today, as I was testing things before our first trip it came to my attention that the water heater was making a whining sound. I didn't notice this during the walkthrough at the dealer.
Now, before I fired it up I hit the pressure relief valve to be absolutely sure the tank had water. That, naturally, got the panel a bit wet. This should be fine, BUT, when I started poking around to find the source of the noise, it appeared to be coming from a strange wiring quirk.
The right brown wire has a strange setup. It looks like maybe there's an in-line fuse or something? It kind of looks like it's wrapped to keep it dry, but instead it's capturing water.
Now, I'm no electrician, but that can't be good.
I've been looking at the schematic and the two brown wires seem to go to the Thermal cut-off and the fixed temp cont t-stat. It looks like a circuit, but again, I'm no electrician.
The line art manual images make it look like that brown should go right into the panel without any kind of add-on.
So what is this thing, why is it there and why is it making a noise?
Details: Atwood GC6AA - 10E. Gas and Electric heat. The sound occurs with either method of heating.
Any input on this would be appreciated.
Thanks,
Bierp
