Refrigerator Thermistor
This NTC resistor provides the control board with resistance values corresponding to the internal temperature. When the internal resistance drifts due to age or moisture, the control board miscalculates the required cooling load, leading to erratic compressor cycling and temperature swings. Replacing this restores the accuracy of the thermal feedback loop.

Air Diffuser/Damper Assembly
In side-by-side models, this motorized baffle controls the volume of cold air moving from the freezer to the refrigerator section. If the gears slip or the motor develops high internal resistance, the baffle may stick partially open or closed, preventing the unit from maintaining a stable set point. A new assembly ensures precise CFM regulation between compartments.

Evaporator Fan Motor
The evaporator fan is responsible for forced convection across the cooling coils and throughout the cabinet. If the motor bearings begin to seize or the windings suffer from intermittent shorts, the airflow becomes inconsistent, causing the thermostat to detect rapid temperature spikes followed by over-correction cooling cycles.
