Fridge Temperature

The Travelling Dillberries · Guru

These suggestions are from the book Captain. I would check with another temperature probe firstly. Then get a dealer to have a look.

The refrigerator does
not cool sufficiently.
The ventilation around the
cooling unit is not sufficient.
Check that the ventilation grille is
not obstructed.
The evaporator is iced up. Check whether the refrigerator
door is properly closed. Defrost
the refrigerator.
The temperature is set too
high.
Set a lower temperature.
The ambient temperature is
too high.
Remove the ventilation grille for a
while so that warm air can escape
quicker.
Too much food at once was
placed in the refrigerator.
Remove an item.
Too much warm food at once
was placed in the refrigerator.
Remove the warm food and leave
it to cool down before putting it in
again.
The refrigerator has not been
operating for very long.
Check the temperature again after
four or five hours.

Ours has a piece of insulation full in on vent through roof . Maybe this has happened also . Seal off any cavities between top
Rear of fridge to roof so it keeps good draught like a chimney . This time of the year it should work well ? Door seals in good nick ? I got sick of making excuses for mine and went to
compressor fridge. Its like Fuel
Injection Vs carb. On
Cars . We just added an extra solar panel.! Are you on level ground ?!

Don't know if yours has the same problems Captain, and mine is a different model to yours, but I managed to get my Dometic fridge working much better (fridge portion down to 2 degrees) by doing the following things...
1. Added two cooling fans to help circulate the air over the rear of the fridge. I wired the fans to a switch inside so that I could select them off, on permanently, or under thermostatic control
2. Upgraded the DC wiring from 4mm2 to 10mm2 to solve voltage drop when running on DC
3. The wife had put nice foam padding on each shelf to stop the contents rattling around as we travelled. Turned out this prevented the necessary circulation of cool air inside the fridge, so stuff next to the cooling fins and temp probe were fine, but everywhere else in the fridge was too warm. Removing the foam and making sure each time we packed the fridge there were air gaps down the back to assist natural air circulation solved this.
Hope that's of some assistance...

at 6 months old, I'd be taking Dill's advice, double checking and taking it back to the dealer.
Whilst all the other advice applies, if it was a used unit to try and trouble shoot it and fix it yourself.
Since it's a warranty issue, there is no way I'd be trying to fix it myself or even diagnose it.
Straight back to the dealer to sort it. its their problem, not yours.

good luck with it

Like you Captain, we put a new fridge (RMDX21) in our van about the same time in WA. It was doing the same as yours, took it to Dometic. The problem was that the air vents for the fridge were too small and had to put bigger ones in (top & bottom) as well another one for the flue for the fridge. Hope this helps you. cheers reg

Almost certainly not installed to the fridge manufacturer's specifications.
Van builder's problem.
Cheers,

Exactly. The installation instructions are available on line and need to be followed to the letter, especially regarding confining the air flow up past the cooling coils and eliminating dead space above the fridge

Is it level ?
