Inverter Not Working

[Fallont22]

Hi all,
We have a 2016 Sandpiper 377FLIK.
We experienced a power outage on the shore power pole last night. I went to go flip the switch to the inverter so the fridge would remain on and run off the batteries (residential size fridge), but the inverter button would not light up when flipped. The water pump would turn on, lights were coming on, but could not get the inverter to do its thing for the fridge.
I am GUESSING it may be a blown fuse, as every time we have used it prior when traveling it has turned on while in tow. Now that the shore power is back on, it is still not turning on.
Does anyone know where the inverter is located, or have any ideas what could be going on?

In addition, when using the batteries (we have yet to dry camp) what outlets work if any? None were working to my knowledge while we were running on batteries.

Thanks!!!

This applies to probably 95% of all units:

With no shore power, and assuming you're asking about 110VAC outlets, NO outlets will work, except what's powered by the inverter, which is most likely ONLY the residential fridge.

But the only way to know for sure is get the inverter running, unplug from shore power, and put a test lamp/meter on each outlet.
