Okay I called the service department and while I am waiting for their call back I figured the forum members could also jump in.
The Suburban water heater (in 120v mode) in my 365 quit working on our last trip. We switched to the 12v/Propane mode and finished the trip without any problems. Trouble shooting it at home
1) I first checked for 120v at the heating element - no joy.
2) I checked the 120v T-Sat/circuit breaker for voltage - no joy.
3) I disconnected the T-Sat and checked continuity it was good.
4) I checked the 120 vac secondary switch in the water heater panel and it was good also.
5) I checked ALL of the 120 circuit breakers in the master CB panel and while none of them are labeled for the water heater, none were "thrown". I reset all of them as a mater of principle.
6) The 120v switch to normally turn the water heater on checked okay. While I did not check the exact voltage I got a differential across it when switched.
I am out of ideas but my main question is where does the 120 vac for the water heater originate.
