Inverter not taking over when power is lost

[ducksface]

Does anyone have the part number for the 2020 style switch, and is it just an r&r job?

My Thor super c did that once. It turned out to be a strange looking circuit breaker in the battery bay. It didn’t look like any breaker I had ever seen. Seems like it was red with a yellow thing that popes out.

As a test I also started everything back up on generator power, then turned off the generator. When the generator went out I noticed the whole coach was off and the inverter did not click back on.

Is this normal? I would have thought the inverter would have stayed on the power the fridge.

I have a 2018 Thor Aria 3901 class A I had electrical issues (gfci) I called Thor and they knew what my problem was and they sent me a new inverter to replace mine. I have found Thor customer service to be very helpful

The fridge is typically NOT on a GFCI circuit. Normally only the bathroom and kitchen outlets... and whatever others are on same circuit. Microwave and fridge should be on their own circuits.

Was the inverter ON before power was lost? Or in your test?
Typically has an ATS (automatic transfer switch) in inverter, so it will run on shore power/genny when present and battery when power is lost. But I don’t expect it will turn itself on if t was off at the time,
With all power disconnected, turn on inverter and insure it powers the fridge. Then supply power from shore or genny. Inverter should show running on external power.
Disconnect shore or shut down genny, and fridge should continue to run from batteries.

About 2 years ago I had a similar issue with the power going out at the campground and I being gone. When I returned I powered off the pedestal and then turned it back on. The power for the 110 side worked fine but the inverter was apparently cooked. I had to replace the inverter and had no further problems.
