If the voltage drops too low the fridge will switch to gas.
Also: I have found Many RVers have a few screws loose.. No, not those, the ones in the power distribution box.. One of mine took over 2 full turns before I even felt resistance and another FULL TURN to be tight, with the screws this loose teh wires rattle around in the clip and make and break.
There are several other connections that can be flakey as well. Some I've found
Outlets.. the "Qick boxes" are basicall junk, pull much over 10 amps they melt.
and in power line order
THe park outlet (house outlet) Screw loose, bad connection, bad breaker, other issues
The plug, screws loose unless welded connection, bad weld.
The shore cord outlet (if any) this is for detachable cords. had one fall off in my hand once, all six of the internal screws were loose. Let me tell you the owner of that RV was **NOT** a happy camper.. Would loved to have been there when he returned to his dealer.. We got him working.
The INLET (mine, one screw
The Transfer Switch (Only applies to rigs that have 'em, this one is rare though)
And a few Junction boxes.
And last, this is very very very very rare.. I had a wire go bad.. Yup, a couple of feet from the end of the wire (This was a DC lead) was a "bulge" I cut it open and it's all corrosion, no connection, cut back both ways to good wire, Solidered and sealed, all good since.
Home was where I park it. but alas the.
