The barn GFIC is tripping on my Wildwood with Dometic RM2652. I has happened 2 times so I replaced the GFIC with a new one and it tripped again. I turned the refer on in case we needed extra storage at Thanksgiving and again at Christmas. It seems to be related to the refer. Electric heater element? Everything else is off other than the converter during storage.

Has it ever worked normally on this outlet? Does your rig have an onboard generator?

Does it trip breaker on propane mode? Use just your battery to see if it runs on propane.

Unplug the refer in the outside access.
Element going to ground!

It has worked for years on that outlet, but since I replaced the GFI it's a moot point. No generator.

Open the outside refrigerator panel and unplug the refrigerators 120v cord from the outlet. Now see if the barn GFI continues to trip. If so then it's not in the refrigerator.

If no tripping then plug the refrigerator back in and disconnect the refrigerator heater wire. If still no trip then replace the heater.

simply plug into a non-gfi circuit. You are not plugged into a gfi circuit when on shore power in a campground.

I posted this in another thread a few days ago, but it applies here as well. Plugging into a non-GFCI circuit doesn't solve a problem that you have, it only fails to detect it.

It takes some serious diagnosing to find GFCI problems sometimes.

1. Turn off all breakers in the RV. If the problem goes away, it is one of the hot wires leaking to ground. Turn the breakers on one at a time to identify the wire, then trace it. If the problem persists with all breakers off, it is not a hot wire leaking to ground.

2. Disconnect all neutral wires in RV breaker box. If the problem goes away, one of the neutral wires is touching ground. Reconnect each neutral one at a time to identify the wire, then trace it. If the problem persists with all neutral wires disconnected, it is not a neutral touching ground.

3. If the problem persists after #1 and #2, the problem is either the outlet, or between the outlet and the breaker box. That means one of the adapters, the plug on the RV, the point where the RV power cord is connected to the RV, or the ATS (if you have one).

It should go without saying, but I will say it anyway, UNPLUG THE RV BEFORE WORKING IN THE BREAKER BOX!
