Yesterday I noticed my KitchenAid side by side refrigerator was running way too cold. Everything on top shelf was frozen solid.
Did you happen to measure the temps in both sections? If yes, post them here.
I set the controls for both the freezer and refrigerator all the way to "warmer" and overnight the temperature on the refrigerator top shelf rose to about 37 degrees.
What is the freezer temp measured at?
I understand this could be due to the damper control or temperature sensor.
Yours doesn't have a temp sensor.
It does have an Air diffuser assembly from freezer into refrigerator
