12v refrigerator /freezer

We had trouble with our refrig cooling. We discovered that it was installed by the trailer manufacturer and did not meet the specs required by the refrig manufacturer. I removed the obstruction (a metal flap of siding folded into refrig compartment) to expose the heat exchanger fins to airflow. WOW! What a difference. Unit cooled and the freezer excelled in all types of hot weather. Check for obstructions, it may not be the refrigerator at fault.

Installed correctly? Temperature setting cold enough? Defective? Mine have always worked fine even in south Louisiana heat in mid summer.

what have you done to remove the heat faster from the RV-frg... a fan in its exhaust... inspection for restriction/blockage...

many work fine.. maybe yours is defective... heat exchanger is vented Well ??....

most RV's are assembled in a Great Rush... not for proper installation... and function.

my opinion..

my 2005 trailer RV frg works well in 100 degree Texas heat... and we do not use air conditioning inside trailer. just fans.

I am curious, what are you going to do with the heat?

If you can vent the refrigerator heat that would be good. Otherwise it goes into the room.

Also, how do you power the frig while moving?

Another option would to purchase a portable unit, some even stand upright VS like a cooler. Their temps are adjustable all the way down 0 some below... they are not cheap but we don't always use the camper sometimes we travel and having a cooler that can go into motel rooms and the truck is very handy...
