Dometic Refrigerator warm freezer cold

[Muledeer2]

Help me please my Dometic refrigerator is acting strangely, the freezer and refrigerator are both cold when plugged into Ac, but if I run on Propane the refrigerator does not get cold but the freezer still makes ice cubes. After cleaning it and find nothing I am a bit stumped, do I need to add a fan at the rear of is a cooling loop plugged some where? has anyone else had this problem and what is the solution?
Thanks in Advance for any advice you can give me.

When my Dometic had the same problems. It turned out to be a dirty LP orifice. Removed the orifice and soaked it in alcohol for 1/2 hour. Blew it out with a low pressure air hose. Then installed back in fridge. You should be able to hear the flame burning from rear of fridge. It will not be as loud as a water heater. But with your ear about 12" away from burner you should hear it.

The burner also fills up with crystals that block air flow.

Ours was doing odd things so we looked and observed wierd flames.

Took it apart and a bunch of what looked like red sand came out.

Cleaned all and good as new.

Locate the maintenance section ov your manual or on line support for instructions for your unit for normal maintensnce and it should show how to do it correctly.

What is the actual refrigerator box temp when cooling on AC power?

If it's not good on LP, it could be low LP pressure, dirty burner, dirty orifice, missing/corroded/rusted flue baffle, or blocked burner flue.

If it is truly down to temp spec on AC power, then you don't have a blockage on the cooling unit, and you don't need a fan on the coils.
