Recently freezer temp went up to 30, ice maker forming tiny wet cubes, fridge not colder than 36.
I have run all of the diagnostics in the service manual and on the tech sheet. All passed.
I opened up freezer to find iced coil. I defrosted it. Checked resistance of bimetallic thermostat and heater - both OK. Fan is working. Put it back together but no change in FC and RC temps. I can feel the 3 way valve moving during diagnostic.
I donít have expertise or equipment to check sequential dual evap system.
I am at install new control board ($300) or have tech repair or buy new fridge. This one is 5 years old.
Any help from experts is greatly appreciated. This is beyond my smarts.
