Well , the cooling fins are metal ...
We have a camper with a dual-power refr. unit . It stopped suddenly on
Monday ... It's a Dometic RM2652 unit , if that helps . I haven't been
onsite to diagnose yet , but have downloaded a few pages of diagnostics to
my thumb drive . Preliminary indications are towards a main board gone T/U

Does anyone here have any info on common weaknesses of these units ? Is
the main board a "usual suspect" when they just die ?

Servel-cyle units are pretty solid, unless they develop a leak in the
sealed system (which happens pretty often at about 10-15 years age, since
the system is all iron pipe, which rusts).

Since the heating element leads are exposed clearly in all RV units, you
might consider disconnecting them and powering the (120V) element
directly from a patch cord. If the unit cools, it's the controller.

We have such a refer in our 5th wheel. Runs on either propane or 120
VAC shore power. Type of power to use is selected by push button at
the top of the unit. You didn't say which was being used when your
unit stopped. If it was using propane, did the propane bottle run
empty? Did the "fault" light come on?

Each year before we start camping, I pull the outside cover and blow
all the dirt, spiders and other stuff out with compressed air. Lots of
stuff comes out!

The units run on ammonia gas and if this leaks out, the cooling stops.
Have you smelled any ammonia in your camper? Well, you said you
haven't inspected the unit, so I guess you wouldn't know, yet.

Hard to guess until you know more.

dual power as in 12/110, 12/lpg, 110 lpg?

The electric part of an LPG dual power is just a strip heater to take
the place of the pilot flame. The biggest problem with lpg fridges is
dirt on the "pilot" flame or nests blocking the draft.

Have had a thermocouple go bad. Bad connection on the 110v side and bad
thermocouple on the gas side.

I had one quit because a wire came loose. There are some things inside the
cover that need a tester and a trained tech, but some things, like spider
webs and mud dauber nests and hanging wires are obvious fixes.

I found the bad AC connection when pulling out the gas thermocouple. The
spade connector was not in the spade part, but was touching, at least for a
while, inside the plastic shield.

Yup , that's one of the suggested tests . Thanks !

The wife is there , it's where she stays during the week to save driving
time . No ammonia , so we think the sealed unit is OK . I'll take a
compressor ... Thanks !

Hopefully it'll be something simple like that loose wire or blocked airflow
.. Thanks to both of you !

My BIL, who is not mechanically inclined, plus lazy, took his to the dealer.
It sat two weeks. He finally went over and raised hell. The manager had
the tekkie look at it. He found a broken wire and a spiders nest. Fixed it
in five minutes. Charged him $180 for two hours labor.
Sometimes, one can fix them. Other times, it's time to take it to the shop.
If you know anyone familiar with electronics, they can help trouble shoot a
relay or other device very inexpensively. They are expensive to have worked
on because there aren't a lot of people who are familiar with them, and
secondly, they got you by the grapes.

I'm moderately adept at troubleshooting stuff . Especially when I have about
20 pages of info downloaded onto a thumb drive ... plug it into the laptop ,
got all the tests right in front of me .
Technology's just alright with me ! I suspect the main board is gone ,
which is about a hundred bucks plus shipping . Hey , I might get lucky and
find something cheaper to repair . I should know by Saturday afternoon !

You probably already know that the fridge has to be level (or bouncing
down the road) in order to make "cold"... and if you smell mouse ****
inside, it's probably the ammonia leaking out of the cooling system.
Every time my brother-in-law called about his fridge not working it was
because he didn't have the RV level... except the last time, when it smelled
like mouse **** and I had to replace the entire cooling section with an
Amish-built super-cooler.
I think we bought it from these guys:
