LG washer main control-board PCB assembly. The original part number is discontinued or no longer available through some distributors and has been replaced by LG part CSP30000805.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.
