Fridge running on 110V still requires 12V to run the controls. I might suspect that the converter is going bad. If that's the case then check your batteries as well as they could be bad.
Basically without 12V your trailer is dead...though you could still watch a DVD on the TV.

It was the battery, the cutoff switch was in the wrong position and we ran it dead.
We changed it to the “On” position and let it charge overnight and everything seems to be working now.
The previous owner had blacked out the switch position marking and just write “No” over them, so we didn’t know where it should be positioned while connected to shore power.
Thank you so much for your assistance.
