Cross Reference Information

Part Number EBR88859921 replaces AP7010083.

Description

This main power control PCB manages the appliance's core electronics and cycle functions, restoring control to motors, sensors and user-interface components when the original board fails. Replace a damaged board to recover normal operation and control responses. What it does:

• Regulates power distribution to motors, valves and sensors so cycles can run correctly.
• Interprets user inputs and runs programmed cycles from the console or touchscreen.
• Reads sensor signals (temperature, door, water level) to enable appropriate cycle changes.
• Prevents operation when critical faults are detected; failures can cause no-start, unresponsive controls, or error codes.

What's included:

• One main power control PCB assembly.

Install notes:

• Disconnect power before starting; verify outlet is de-energized to avoid shock.
• Handle the PCB by its edges and avoid static discharge—use ESD protection if available.
• Take photos of wiring and connector locations before removal to ensure correct reassembly.
