SAMSUNG FRIDGE RF24R7201 Not Cooling

Main Power Control Board

This central electronic module regulates the inverter compressor and the Twin Cooling fan speeds. A failure in the board's microcircuits or relays—often caused by voltage surges or thermal degradation—prevents the compressor from initiating or maintaining the cooling cycle. Replacing the board restores the communication loop between the temperature sensors and the cooling hardware.

Refrigerator Evaporator Fan Motor

In Twin Cooling Plus models, the refrigerator compartment uses an independent fan. If the motor fails or the blades are obstructed by ice buildup (common in Samsung French Door units), the fridge will fail to cool even if the compressor is running. This part is essential for circulating chilled air from the evaporator coils into the food compartment.

Internal Temperature Sensor (Thermistor)

The thermistor monitors the internal temperature and provides feedback to the Power Control Board. If the sensor's resistance values drift out of range, the board may 'believe' the unit is already at the target temperature and fail to engage the compressor or fans. Replacing this sensor ensures accurate thermal monitoring and proper cooling cycles.
