Dometic Fridge

1. Your freezer temp measurement is WRONG
2. The Icemaker will NOT make ice until the freezer is BELOW 10 degrees
3. From your refer temp and the fact that it makes ICE and dumps means your refer is at spec. Doug

Freezer 'warm' & food compartment holding temp.

Freezer section gets cooling affect FIRST ----THEN food compartment

Fridge on 'coolest' setting and freezer NOT going below 26*F but food compartment at 32*F-34*F suggests obstruction in Freezer Low Temp Evap Coil.

Not a issue with circuit board, thermistor, LAC, Ambient air temps etc
Cooling unit process is functioning overall otherwise food compartment temps would NOT be at 32*F
If Freezer Evap Coil was fully functioning the freezer temps would be at 0*F or lower with those temps on food compartment.
Obstruction/Blockage.

What is MODEL Number?
RM1350?



Check Freezer Door Seals for leakage.....door bill test
But if the door gaskets didn't fully seal freezers should have excessive frost build up

Seem as though it is installed properly, including exhaust fans on a thermostat. I will look for the LAT switch.

X2.
I have never seen an OEM install that was exactly as instructed by the firdges manual.
Making these modest changes made a huge difference to our last TT which had the same fridge as yours. It had no problem even in tripple digit temps and running on elect.

This is what I suspect is the issue and why I asked what the ambient was. Refrigerator is cold so the heater shuts off.

I'm going to take a shot and guess your fridge is in a slide. Fridges worked much better prior to slides when they had a vent directly overhead and air circulation was much better. We have a Norcold but the same issues apply to them when they are put into a slide and have to rely on two sidewall vents to carry the heat away. This is what I did this year. Waiting for the coming summer to see how it works on really hot days but so far, so good. May still reverse the airflow as I originally intended if I find it necessary.

What is the ambient temperature and how long have you let it run?

Alas,

It is quite often so. Does this model have a thermistor on the cooling fins?
