Thermistor
The thermistor is a Negative Temperature Coefficient resistor that signals the control board to cycle the cooling system. Over time, moisture ingress into the sensor housing causes resistance drift, leading the control board to receive inaccurate thermal data. This results in the compressor cycling on and off at incorrect intervals, causing the cabinet temperature to swing outside of the calibrated 2-degree delta.

Refrigerator Air Damper Control Assembly
This motorized gate regulates the volumetric flow of sub-zero air from the evaporator coil into the fresh food compartment. If the internal plastic gearing strips or the synchronous motor develops a dead spot, the damper may remain partially open or closed. This mechanical failure prevents the unit from achieving thermal equilibrium, causing localized temperature spikes or drops regardless of sensor accuracy.

Main Power Control Board
The main control board manages the logic gates for the cooling cycle and defrost termination. If the board's electrolytic capacitors degrade or the switching relays for the compressor/fan circuits experience contact pitting, power delivery becomes intermittent. This disrupts the logic loop and prevents the refrigerator from maintaining a steady-state operating temperature.
