WHIRLPOOL FRIDGE WRX986SIHZ Not Cooling

Evaporator Fan Motor

This DC fan motor is responsible for circulating cold air from the evaporator coils into the refrigerator and freezer compartments. In this specific model series, the fan often fails due to moisture intrusion or bearing wear, causing the compressor to run without actually lowering the temperature in the food cabin. If the motor is seized or the controller cannot detect its RPM, the cooling cycle is often inhibited.

Main Control Board

The main PCB controls the dual-evaporator system and the linear compressor. As noted in research for this model family (WRX986), the board's internal relays or capacitors can fail, leading to random shutdowns or a failure to send 120V to the compressor. Replacing the board restores the logic required to manage the complex cooling algorithm of a 4-door unit.

Compressor Start Relay

The start relay is a high-wear component that provides the electrical surge needed to kick-start the compressor. If the user hears a clicking sound every few minutes with no cooling, the relay has likely shorted or burned out. This is a common failure point on Whirlpool compressors and prevents the refrigerant from circulating through the system.
