Kenmore Side By Side Fridge Warm Freezer Good

Hello again!
Its been a couple of years, but I am back with a new problem :wink:
I have a Kenmore 106.53606201 Side by Side. There seems to be a problem with the fridge not getting down to a proper temperature, while the freezer seems to be working as expected. Here is what I know:[LIST=1]
*]Freezer is at zero
*]Fridge holds around mid 40s if left closed overnight (Set at 33)
*]Evap coils show a good frost pattern
*]Evap fan is running
*]Coil heater is working
*]Removed fridge thermistor and at room temp it was showing ~2.7k Ohms
*]Ran diagnostic and observed damper motor moving. (it was replaced 2 years ago)
*]Removed back panel feeding the damper and observed no blockage of ice.
*]There is cool air blowing into the fridge.[/LIST]Any advice as to what else to check?
Thank you!

Hi, Craig.

You need to determine if the air diffuser opens all the way during the test. If itโ€™s not, pull it out and check if the curtain is not damaged. If the curtain opens completely jam it with a pencil (careful not to break it) to keep it open and check the temperature after a few hours. If the temperature will go down to normal or even colder, the thermistor is within the range and the air diffuser opens up completely itโ€™s sounds like the main control board. The bad news are that it is no longer available.

The air diffuser AP3084126

The control board 8201528

Thank you,

Simon.
