I own a Momentum with two gray tanks (kitchen/WD)(bathroom), two fresh water tanks (~150 gallons), and one black tank (bathroom). Assumption was the tank heaters for all of them were wired through OneControl and when set to off, power would not reach any of them.
I'm camped in Arizona and it got below the thermostat setting of the Facon tank heaters for several nights. When I opened the door, I could smell something hot/electrical like when a space heater overheats, etc. Initially, I didn't believe it was me as the only thing I had on was the exterior LED lights. I opened the front bay and pass-through and the smell was not coming from either of them. I even removed the interior panel to make sure.
The second night, it did it again and it was pretty strong so I turned off the LED lights and although the OneControl switch was off for the tank heaters, I also pulled the fuse. The next night, everything was fine. Although the LEDs were still working, I suspected perhaps a control box was getting hot. I placed the tank heater fuse back in and the next night, the strong smell did not return.
A couple of days later, it was really bad again and it was then I realized that on the days it happened, the tank heater fuse was installed AND the bathroom gray tank was empty. There had been no changes in the fresh water tank levels (basically empty) and the black tank was more than 1/2 full the whole time. The rear gray tank was too far away. I pulled the tank heaters fuse again and have not had it happen since. I obviously need to check the tank heater on the front gray tank.
I received the Facon manual with the trailer but the component sheet doesn't list versions, sizes, or where installed. I posted a question on the Grand Design main site a month ago but received NO reply even after following up a week later.
Does anyone know how the Facon tank heaters are wired on the Momentums? (349M specifically)? It acts like one or more are powered and turn on when below the default thermostat setting even though they have been turned off in OneControl the whole time. I know I'll need to drop the cover and check with a meter/heat sensor but wanted to gather any information you may have first.
