My LG model LRMVS3006S is not cooling properly

Hi jayeff.

The tech had gauges attached so I assume he checked all the pressures. He spend almost three hours here doing his business.

Yes I do have a thermometer in each portion of the cabinet. Fridge, middle door and freezer. I also have a meater probe which reads internal and as well ambient temp. It matches within one degree of the analog thermometer. One thing that is important that I understand is the operating temperature. Can you please answer my question about the temperature range I should expect with a normally operating fridge set at 37˚F? This way I will know if it is normal or something I need to do something about.

The manual doesn't specify (or at least I couldn't find it) but usually refrigerators have upper and lower preset limits around the user set temperature within which they operate, usually about 5°F degrees.

They do try to stay near the set limit however e.g set for 37°F may rise to 40°F before the compressor kicks in to lower it again and goes down to 35°F before it stops.

A lot also depends on the ambient temp and also how often and for how long the doors are opened through normal usage which affects the temps in the compartment. First thing in the morning is probably the best time to check as overnight there is usually less user activity so everything is more stable so to speak.

All you can do is check the thermistors to see if they are having the correct resistance value for whatever the temperature is at the time.
