Customer Questions and Answers for Power Control Board (Pcb Assembly) by Lg

Power Control Board (PCB assembly) that manages incoming power and distributes voltage to the appliance's control, motor and sensor circuits. Replacing a faulty board restores reliable power delivery and control to affected components. What it does:

• Regulates and routes power to control modules, motors and sensors — symptoms include appliance not powering on, intermittent shutdowns, or failure to start cycles.
• Supplies and stabilizes voltage for the control panel and displays — symptoms include dim or blank displays and intermittent or erratic control behavior.
• Interfaces with user controls and safety switches to enable normal operation — symptoms include unresponsive buttons, stuck cycles, or error codes.
• Contains protective components that can fail visibly — symptoms may include burning smell, scorch marks on the board, or tripped breakers.

• Disconnect power (unplug or switch off breaker) before accessing the appliance.
• Photograph wiring and connector positions before removal; compare connector types and board part numbers to fit.
• Avoid touching board components and use basic ESD precautions when handling the PCB.
