Refrigerator Thermistor
The thermistor acts as a temperature-sensitive resistor that provides the control board with data to manage cooling cycles. If the internal resistance drifts outside of OEM specifications, the control board receives inaccurate thermal data, resulting in 'hunting' or wide temperature swings. Replacing this sensor restores the integrity of the thermal feedback loop.

Main Control Board
The main control board processes sensor inputs and executes the cooling logic via relays to the compressor and fans. Component-level failure on the board, such as a degrading capacitor or relay in the cooling circuit, can cause erratic power delivery to cooling components. This results in inconsistent cycling and inability to maintain a steady-state temperature.

Air Damper Control Assembly
The damper is a motorized baffle that regulates the volume of sub-zero air moving from the evaporator compartment to the fresh food section. If the plastic gears strip or the motor windings weaken, the damper may stick partially open or closed. This mechanical failure leads to over-cooling or under-cooling phases as the cabinet fails to isolate from the freezer air source.
