Description

This main PCB power control board assembly replaces a failed control board to restore the appliance's electronic control and power distribution. It's the central electronics module that manages the appliance's control signals and power pathways. What it does:

• Regulates power and coordinates electronic control signals; a failed board can leave the appliance without power or prevent it from starting.
• Interfaces with the user controls and display; failure may cause unresponsive buttons or a blank/erratic display.
• Processes sensor and component signals; faults can produce incorrect behavior, error codes, or intermittent operation.
• Routes power to motors, fans, and other circuits; a damaged board can cause those components to stop working or run intermittently.

What's included: One main PCB power control board assembly. Install notes:

• Always disconnect the appliance from power before inspecting or replacing the board.
• Use basic ESD precautions (ground yourself) and label harness connectors before disconnecting to ensure correct reassembly.
• Visually inspect connectors and any onboard fuses for damage; replace blown fuses or damaged connectors as needed.
• After installation, restore power and verify normal operation of controls and affected functions.
