Have you run diagnostics?
... i see earlier you said you looked at evap.......how about evap fan motor is it turning with sufficient force?
Also check for other heat sources... are lights turning off? Defrost heater running while compressor on.... looks like you have the utah board configuration.. i think, a close cousin to the jazz boards. Heater running with compressor on is a common failure, at least in the jazz board variety. If you have a heat release icemaker, make sure the heater turns off on that as well....
theory... a heat source in either compartment may cause temperature over compensation.
