Part Numbers: DA92-00530A, DA92-00486A, STD32W, STD45W
Models: NZ63*, NZ64*, RS51*, RS53*, RS57*, RS5G*, RS5H*, RS62*, RS66*, RS67*, RS68*, RS6G*, RS6J*, RS75*, RS76*, RS77*, RS78*, RS7G*, RS7J*, RS80*

Components: DS2 (Diode: SB2100), RP02 (Resistor: 10Ω)

Fault: Intermittent or unstable 12V output and missing 5V

The 12V output tends to pulse, while the 5V output is consistently absent. This issue is typically associated with diode DS2, and occasionally a faulty resistor RP02.

This is a common problem in models using this board, often resulting in a non-functional fridge freezer
