GFCI Fault

[GFCI Fault]

The GFI tripped on his circuit when he plugged in the ice maker. When its not on (ice maker) the GFI works normally.That to me says the Icemaker is OVERLOADING the circuit and tripping the breaker. Now it may just be a weak GFI. That said its not the ice maker because it does not trip the next GFI circuit he plugs it into. If there was moisture in the circuit(example) the GFI should be tripping with any load

SO when a GFI trips it may be a unbalance as you describe or a overloaded circuit as I describe.

Wrong... You obviously do not understand GFCI receptacles. They are NOT load sensitive, they detect leakeage between return and ground.

It is obvious to me that the ice maker has a short (or partial short) from neutral to ground, probably at the heater element that loosens the cubes. This condition often occurs in water heater elements.

[Chassis Batteries Not Charging]

Why did no one here even bother to ask the OP what kind of motorhome he has? With that information, we could determine if it was equipped to charge the chassis batteries, and thus just failing, or if it was not so equipped.

I used RMP-3 on my 16 year old Bounder about 10 months ago and it still looks great. I bought 10 gallons of it (2 5-gal jugs) during Lowe's close out for $4.99 each. I won't live long enough to use it all.
