LG PCB Assembly, Main / Washer Main Control Board EBR65989427 – Superseded by CSP30000805

Is This the Right Part?

Common Symptoms

• Washer does not start or respond normally after basic power checks
• Cycle stops unexpectedly or fails to advance
• Motor, drain, fill, or spin functions may not be commanded correctly
• Persistent control-related error codes after the associated wiring and components test normally
• Intermittent operation caused by damaged, loose, or corroded board connectors

Check Before Replacing

• Confirm the washer is connected to a working outlet and that the circuit breaker or GFCI has not tripped.
• Unplug the washer before inspection and check the main-board wiring harnesses and connectors for loose connections, corrosion, damaged terminals, or visible heat damage.
• Verify the full washer model number and compare the board identification label before ordering; visually similar LG boards may not have compatible firmware.
• Check related components and harnesses indicated by the washer’s error code before condemning the main PCB.
• If the washer has no power, check the separate noise-filter assembly and its wiring before replacing the main board.

Installation Notes

• Disconnect electrical power before accessing or replacing the control board.
• Use the complete washer model number and the identification number on the existing board to confirm the correct application.
• Label or photograph wiring connections before disconnecting them, then reconnect each harness to its original connector.
• Inspect connectors and related components before installing the replacement board so an unresolved fault does not damage the new assembly.
• After reassembly, perform the washer’s applicable test or diagnostic cycle according to the model-specific service information.
