Refrigerator Blowing Breaker
My frig will run on 30 amp no problem, but when I plug the trailer into a normal 110 outlet it blows the breaker. I took the side panel off and saw the frig was plugged into a local outlet behind the ...

I dislike the term 'blowing a breaker or fuse' It don't blow, it either melts (fuse) or trips (thermal breaker). If it 'blows' you have issues other than a short to ground or a high amperage draw.
When I was a kid, there was no thermal breakers, glassine fuses or encased in plastic ATO style fuses. We had knob and tube wiring and the 'fuse box' was a series of screw terminals you bridged with (fuse wire), basically solder in various diameters that corresponded to different amperage draws and when the amperage exceed what the 'fuse' would carry, it melted and you corrected the problem and replaced the fuse wire.
Sounds to me like the cartridge heater (also called a Mullion Heater) is shorted to ground. Time to disconnect and replace.... and because the OP has tripped the breakers numerous times, if it was me, I'd be replacing the thermal breakers as well. Like I said previously, continual tripping of a thermal breaker lowers the threshold at which it trips.
