- Q: I have an ammonia smell in my RV's refrigerator,
and it has stopped working!
- A: The smell is coming from a leak in your refrigerator's
core — you need a new fridge. You can replace the core with
a new core, and it is cheaper than a new refrigerator, but remember
that all of your other components are used. If you have a brain board
go out, you could be spending another $300-$400 to replace the board.
When purchasing a re-cored RV refrigerator the warranty is only on
the replaced core.
- Q: I was told if I turned my refrigerator
upside down it would start working again?
- A: A refrigerator core is like a clogged artery.
Turning it upside down may break the core loose but once it collects
up again in the line it will stop the flow of ammonia and stop cooling.
You need a new fridge.
- Q: Last year I put my RV away for the season and
my fridge was working fine. But now it won’t get cold. What's
wrong?
- A: RV refrigerators need a 12 volt source to operate
the brain board. Make sure your battery is charged, or the refrigerator
will not come on.
- Q: My RV refrigerator works great on gas, but not
on 110 volt.
- A: If it works great on gas, your problem could
be a bad heating element, or it could be a board. Some refrigerators
have a separate thermostat for gas and one for electric.
- Q: My refrigerator gets cold on the top but not
the bottom. Why?
- A: You probably have a blockage you the coil, you
can replace the coil, but it's recommended that you replace the complete
refrigerator.

Customer's’ recommendation: The
answer is the outside temp is too hot for the condenser to condense
the ammonia vapor back to a liquid; what vapor is changed back to
a liquid is used up in the freezer section leaving no or very little
liquid for the refrigerator section. When this occurs put a good
thermometer inside the refrigerator section and at night when the
temp cools the refrigerator temp will drop and the next day when
the temp rises so will the temp inside the refrigerator. The cooling
unit is good, there is no blockage, it just needs some help. The
solution is more air movement through the condenser coils/fins. 12v
fans...can solve this problem it is common down here in the Houston
area.
- Q: How cold should my refrigerator get?
- A: 40°F is the food safe zone.
- Q: My RV refrigerator takes a long time to get cold.
Why?
- A: The refrigerator in your house blows cold air
into the box and makes it cold, but your RV has what’s called
"heat exchange", meaning it absorbs hot air. The more it
absorbs out of the box the colder it gets. It’s best
when stocking your refrigerator to have the items already cold to start
with. If you have children getting soft drinks a lot of the time. Keep
soft drinks in another cooler (ice chest) to keep from open and closing
the door so much.
- Q: I have a 1988 Escaper Class C. I am experiencing
problems with the refrigerator. It's making a boiling or gurgling sound
on LP and electric and it will not get cold. The fridge worked perfect
at the end of the season last year. It will turn on but it will not
get cold. What should I do about this problem?
- A: You have a bad cooling unit. Replace the cooling
unit or the complete refrigerator.
- Q: My Dometic refrigerator's check light is on, what
do I check? Is it on gas or AC?
- A: Make sure the gas is on and you have gas. If check light is on
you are on gas.
