Could a failing Inverter Power Control Module cause the BOSCH B36CT80SNS to have symptom: Not Cooling?

This module is responsible for converting household AC power into the variable frequency DC current required to drive the compressor motor. The clicking sound is the result of the board's internal protection circuit or startup relay cycling as it fails to overcome the compressor's back-EMF or due to internal component degradation on the board itself. Replacing this module restores the precise electronic commutation needed to initiate the refrigeration cycle.

Could a failing Main Power Control Board cause the BOSCH B36CT80SNS to have symptom: Not Cooling?

The main PCB communicates with the inverter board via a low-voltage DC signal; if the logic circuit or the communication relay on the main board fails, it can cause intermittent signals that lead to the clicking sound as the system attempts to initialize. This component oversees the defrost timing and temperature sensor feedback, and a failure here prevents the compressor from receiving the steady 'run' command.

Could a failing Electronic Refrigerant Switching Valve cause the BOSCH B36CT80SNS to have symptom: Not Cooling?

In dual-evaporator systems like the 800 series, a 3-way 'step' valve directs refrigerant flow between the fridge and freezer. If this valve's internal solenoid is physically stuck, it will produce a repetitive clicking sound (homing failure) and may prevent refrigerant from reaching the evaporator coils, resulting in no cooling even if the compressor is running.
