Temperature Sensor (Thermistor)
This NTC thermistor provides the primary thermal feedback to the control board. Resistance drift caused by moisture penetration leads to incorrect voltage signals, causing the compressor to cycle at improper intervals and resulting in temperature swings. Replacing this restores the accuracy of the cooling feedback loop.

Evaporator Fan Motor
The evaporator fan is responsible for forced convection within the cabinet. If the motor bearings are failing or ice is beginning to accumulate near the shroud, the fan may intermittently stall or slow down. This leads to uneven air distribution and localized temperature fluctuations regardless of compressor activity.

Main Power Control Board
The PCB contains the logic for interpreting thermistor data and driving the inverter compressor. If the logic gates or electrolytic capacitors on the board fail, it may fail to maintain a steady PID loop for temperature regulation. This is considered the root cause if sensor and fan data are confirmed to be within nominal tolerances.
