Question Where's the ground fault for the fridge?

Having major brain farts. We can not locate the ground fault for the fridge for our 2002 Dynasty. Our Norcold fridge has been repaired (recall) & it ran fine. I went into the MH to check things & discovered the NOAC code was flashing. We have power because the light inside works. We have tried to reset it & have checked the plugs & fuse outside. We were told to check the ground fault but can not find it: Any help would be greatly appreciated.

Mine did that recently and it was a failed control board. When the board was replaced the wrong one was installed requiring both the internal board and the panel on the front of the fridge to be replaced. Norcold had sent the wrong board the first time.

The interior light is 12v and works as long as there is 12v power to the circuit board. The NOAC code means there is no 120vac power and has nothing to do with 12v power (which means your fridge should still work fine on propane).

A "ground fault" refers to a trip GFCI on the outlet, or another outlet upstream from the fridge. Try this to figure it out: Remove the outer access door in the exterior sidewall behind the fridge. On the left side you should see a standard 120v outlet that the fridge plus into. There may be two plugs - one for the fridge and one for the icemaker. Remove the plug(s) and plug in another electrical device, e.g. a small lamp, and see if that works. If it does not light/work, your fridge is fine and the problem is in the 120v supply circuit. If the other device works when plugged into the fridge outlet, then you know the problem is in the fridge. Let us know what happens and we can help further.

When my board failed my interior lights would burn but code read NO AC (there was AC at the plug). The fridge would not work on AC or propane, in fact the panel would also read NO LP even though there was a full tank. The board and the control panel were not communicating. It was totally frustrating.

If you have 120 at the refer plug in the back, pull cover off of black control board on the bottom back of the Norcold and there should be two fuses. one for 12volts and one for the 120 volts. Check them.

I doubt the fridge is wired from a ground fault. If it is, it's most likely in the bathroom area. Maybe kitchen counter area.

Though some Motor home makers DO put the fridge on a GFCI

The Fridge should be Grounded to the frame and thus does not need GFCI protection

Check for a tripped circuit breaker and also check to make sure that employee number 1-D-10-T did not forget to plug the thing back in (That would be in the outside fridge service compartment)

Often a refrig. is not protected by a GFIC. If it tripped and nobody knew it, the food in it would spoil. (In houses, the refrig. is not on a GFIC either.)

never seen a gfci on a fridge. Should be a normal breaker.
