I have a 1972 13ft Burro when i plug it in to shore power I pop the shore power breaker. The furnace is unplugged so I think it is the fridge compressor.
Is this fixable? or should the fridge be replaced (I think it is original ) How would I test this theory?
If you have a 1972 I doubt that it has a 120V compressor type refrigerator
. Most trailers of that vintage used a 2 or 3 way ammonia cycle refrigerator
that has either a 12V or 12V and 120V heat elements. If it uses 120V there will be an outlet in the refrigerator compartment. You can unplug the refrigerator there and see if you still trip the breaker.
probably has a 12VDC blower so that is unlikely to cause a problem on the 120VAC side of things.
I would check out the converter/charger as the most likely culprit. Some of them decide to self-disassemble after a few years of bouncing down the road. Also check the 120V wiring to see if there is some damage, especially if the wiring is unprotected anywhere in the system.
Hoe this helps.
