Battery Power is fine Shore power is not

Scratching my head here. Perhaps someone else has had this problem. I was working on my fridge in propane mode and only on battery for the trailer(no shore power hooked up). Everything seemed to be ok. Left for an hour and came back and the fridge was not working at all and could not get it lit again. Then read that if its warm and humid that you should run it on AC mode for at least 5 minutes. Plugged in to shore power and turned the fridge on and left it go for an hour or so. Came back to check on it and the whole trailer was dark. Works on battery mode (lights & other 12v stuff) but as soon as I try the AC I am tripping breakers (my house/shore breakers) and have a good circuit protection unit (progressive Industries) that just clicks after the 3 minute timer kicks on. Perhaps a bad converter? All fuses inside are ok by the way. Any suggestions would be helpful. Thanks.

    When you say "I was working on my fridge" what does that mean? Was your trailer working on 120v before that?

    EricMuench, Did the GFI plug-in next to the converter trip?

    Assuming you don't have an overload condition on the house circuit, I'd guess a short circuit somewhere. Finding it will be the challenge--it could be in the converter, or anywhere else. Did you try connecting without the surge protector? I would think a short within that unit might cause the house breaker to trip. Again, without a little more to go on, just guessing...

    That shouldn't trip the house breaker.

    It has been suggested to make sure everything is turned off, then plug into shore power to avoid tripping the Tab/shore power breakers.

    I seemed to have narrow it down to the circuit and breaker that controls the AC outlet for the water heater and fridge. Unplugged both and it still trips. Not sureif there is anything else between the breaker and that outlet. When I say I was working on the fridge, Photomom, I installed the aftermarket fan unit from Pleasant Valley. I know, that seems suspect and it may turn out I fried something but that is only DC and I never touched the AC lines. I will get back to you if I figger it out. I hate/love this kind of stuff if you know what I mean.

    No, GFI is fine. Air conditioner works. It seems isolated to the breaker for the water heater and fridge outlet. Not sure if anything else in on that circuit anywhere?

    If it worked before you did something and it doesn't work after, it is almost always related to what you did. Might you have dropped something metallic into some wiring? A screw or a tool? Or did something inadvertently get pushed into some wiring?

    Where does the fridge plug into for 110V?  Is it behind the plastic panel to the left of the fridge, or does it go through the wall into the cabinet under the sink?  I know I saw the actual cord plug in in one of those locations.

    Mine goes to the other side of the cabinet under the sink. That's on an early 2015.

    Same with my early 2015 - Plugs in the back right corner of the upper cabinet.

    @EricMuench, if your fridge is plugged into the outlet under the sink, and the fridge doesn't work, try taking an electrical appliance (blender, corded drill) and plugging it into the fridge's electrical outlet. Does the other appliance work?

    Can you get at the hot water heater and totally disconnected it from the trailer AC and DC? If there's an internal short in the water heater this should stop the tripping

    I found the culprit. The wire that ran from the breaker to the outlet that the fridge and hot water heater had rubbed through on the corner of one of the fridge fins. Since I had the shore power on a GFCI protected circuit of my house, the GFCI was tripping before the breaker of the trailer did. I replaced the outlet with a "multi-strip" hardwired/spliced into the wire to the breaker. All is well now.
    Thanks for all your suggestions!

    I moved that wire (along with the burner wire) away from the fins when moving the hoses.
