Jenn-Air JS42NXFXDE Built-In 42 in 20.7 cu ft Built-In Side-by-Side Refrigerator with Advanced Water Filtration OP Error Fix: Overcooling Protection

The fresh food or freezer area is getting too cold — food may be freezing in the fresh food compartment; the compressor may be running continuously because a thermistor is giving a false warm reading (telling the control it needs to cool more), or the air damper is stuck in the fully open position; check the thermistors in both compartments for correct resistance values; check the damper control motor and position; verify the temperature settings have not been inadvertently changed to the coldest setting
