Freezer side works fine

the evaporator coil is frozen over and cant release cold air due to this,defrost the unit remove rear panel inside freezer and troubleshoot the defrost heater and thermostat and also make sure the fan near this coil is running, on the evaporator coil as,you cant blow cold air thru a coil covered by ice

more than likely the defrost thermostat on the top of the defrost clipped onto the coil is bad,if not it can bethe defrost heater underneath the evap coil thats open and cant heat,or the defrost control board located behind the control panel is bad and not powering the defrost heater and thermostat

Are fans running? Any frost buildup on inside back freezer wall?

Most likely adaptive defrost it out and it's covered in heavy frost in the back wall of the freezer. You fridge part 100% depends on the freezer.

I took the arm of the ice-making machine out of the slot and put it back in, pushing it snugly inside the slot, then raised and lowered it several times. Then, with the arm in the up (stop making ice) position, I felt inside the ice-making tray, where I noted there were ice cubes as well as a sheet of ice at the base of the ice-making tray. I poured approximately 24 oz. of hot tap water into the tray to melt the sheet of ice. I turned the freezer temp control to "warmer". I think the freezer temp setting was too cold, causing the ice maker to freeze the water before it could make cubes. I have a working ice maker again!

Check the circulation fan in the freezer compartment that circulates the cold to the fresh food compartment. If its not running, and no ice is on it to bind uo the blades, replace the motor.

Just had the same problem with my side-by-side.

In my case, the solution was to empty the freezer side, to access a back panel INSIDE the freezer covering the fan and cooling coils. Two screws held the back panel cover on, and when I removed the panel cover I found the cooling coils to be totally iced up, preventing the flow of cold air into the fridge side. I left the freezer open for a few hours until all the ice was melted, before replacing the inside panel. (I used a blow dryer to help speed up the ice melting).

Everything's working fine now for me - good luck with yours!

Yes. I would suggest the control board is possibly damaged.

This is not the only place to look, but it is where I would start.

The panel on the inside back wall.

change the adaptive defrost board located in the upper right corner of refrig under the panel. remove panel by pulling on panel towards you from the finger holes in the rear. remove two 1/4 inch screws and two phillips screws. defrost manually with hair dryer behind panel in freezer.
