Start
Does Fresh food &
Flex zone Door switch operate

PCB CN51 normal?
Is the lighting
operated when replace Pantry
Panel-PCB?
Is a key pressed
continuously?
Is the PCB system
still operated by separating
of the mechanism?
Is the lighting operated
after replacing the Pantry
Panel-PCB?
Is a normal voltage
outputted from MAIN PCB IC74
during the key operating?
Check and repair the switch
* Refer to<how to repair door switch>
Reinsert Connector,
Repair bad contact
Reinsert connector in MAIN PCB
