Hi, I'm Robert. Welcome to JustAnswer. I'm reviewing your question now and will post back with your reply momentarily.

Have you tried running the fridge on propane and does the box get cold using propane after 8 hours?

Thanks, Robert

Runs on propane but box doesn’t cool
RV Mechanic: Robert, RV Mechanic replied 1 year ago

IF the box does not cool on BOTH LP and AC power it can be the thermistor or cooling unit.

What you can do to trick the fridge is disconnect the thermistor, doing this will put the fridge into a full cooling cycle and the box should get very cold after several hours, the thermistor plugs into the circuit board which is located under the outside access panel and is a two wire connector marked P-2 on the board.

IF the box does not get cold then the cooling unit is suspect, inside the cooling unit is an ammonia solution when it leaks out OR stops circulating you loose cooling in the box. For a rupture you might smell ammonia or see a yellowish powder on the back side of the fridge. For a blockage you might not have any symptoms at all but no cooling on BOTH sources, if it cools on one source and not the other then it is normally not a cooling unit problem. What you can do is get a rubber mallet and tap the cooling unit coils and let the fridge run for several hours. Also pulling the fridge, flipping it end over end and letting it stand upright for several hours and see if the cooling comes back.

I started typing this before I saw your response and all of this applies with the no cooling on both sources.

Robert
