Norcold won't work on LP for fridge but freezer OK!

The freezer unit gets the "cooling" first. If inadequate, there is not enough left to absorb the heat in the refrigerator.

Many factors can limit cooling-- these are some of those related to the LP heat source:

Low propane pressure (regulator may need adjustment or replacement
Dirt in refrigerator gas jet
Dirt, rust or insect nest in burner tube

Basically, start by doing a COMPLETE burner area tune-up, not a short cut "blow it out" one.

Check propane pressure to insure it is 11" WC.

Freezer ok, fridge not is the first sign of a problem, or worse a failing cooling unit.

Your freezer should get down to 1 or 2 degrees. The fridge should follow at 34-36...

Refrigerator is NOT cooling sufficiently on LP.
Freezer getting down to 15F is NOT cooling enough therefore food section can't begin to cool down sufficiently.

Not enough 'heat' transfer occurring on LP.
As stated
Low LP pressure
Dirty burner

But most likely dirty/sooted up flue/flue baffle
Flue baffle is key to proper heat trasfer

What is the best source for parts breakdown and access to clean out flue?

What Norcold Model is it?

That unfortunately is also the normal characteristic of a dying Norcold.

Not when it is cooling correctly on AC

It's a Norcold Model 1200LRIM.

He states it works on 120 but not on LP. Why would anybody then state it is a failing or failed cooling unit??????????????????????? LP pressure and burner cleaning is FIRST on the checklist. Once the burner and LP pressure is correct (11.5 inches W/C). then possible flame baffle problem(long shot is the LP orifice). Now, on 120, the freezer should get below 10 degrees. The refer section below 38 degrees. I would verify this before going any further after the LP system is cleaned and checked. Has ANY work been done recently on the Norcold? Doug

Do you hear a slight roar from the LP flame? Is it a steady blue? Is your burner tube rusted and the slots bigger than when new? Do you hear a slight backfiring sound on LP? When was the last time it cooled on propane? After doing a general clean up as others suggested I would look closely at the flame an burner tube.
