Fresh Food Evaporator Fan Motor
In the TwinChill system, this motor is responsible for circulating air over the fresh food evaporator coils. Mechanical resistance in the fan bearings or electrical failure in the DC motor windings causes inconsistent airflow, leading to temperature spikes and drops as the cabinet fails to reach a thermal equilibrium despite the compressor running.

Refrigerator Thermistor
The thermistor acts as the primary thermal sensor; if it undergoes resistance drift, it sends incorrect voltage signals to the control board. This causes the system to prematurely terminate a cooling cycle or delay its start, resulting in the user-reported temperature fluctuations.

Main Electronic Control Board
The control board serves as the 'brain' that processes sensor data and actuates the cooling components. If the onboard relays for the fan or compressor circuits are intermittent, or if the logic processing for the defrost cycle is compromised, the unit will fail to maintain a steady temperature setpoint.
