I have to agree sounds like a failing converter though I have no clue as to why the GFCI breaker has anything at all to do with it.
UNLESS it's on that circuit.
YOu say the fan never comes on.. The fan is controlled either by a straight bi-metal thermostat or more likely by an electronic "Driver" that feeds it different power levels depending on how hot the converter is.. My guess is the driver failed... If that's the case there may be a "Cheat" but.... Well. a progressive Dynamics 9200 is a good plan (Unless the converter is part of the power distribution panel then a 4600)
Update:
When the 15A breaker is on, the converter is clearly powered by that circuit. I took the following readings today with a multimeter;
- No battery & 15A GFCI/Utility breaker OFF = no 12v and no 120V to plugs.
- No battery & 15A GFCI/Utility breaker ON = 12v converter supply to the trailer, and 120V to 120V outlets. But also no fan on converter and a constant alarm shortly after turning it on.
- When ON, I have measured approx 13.2V DC at several points in the system - battery terminal connectors and also at the DC supply points to the 3 way fridge.
- When ON, I have ~122V AC at the 120 receptacles.
What's this "cheat" you mentioned? I'm guessing it's the fan driver or something to do with the temperature measurement and control, since everything else seems to measure what it should.
