Description

This main control board assembly manages the appliance's electronic controls and cycle selections so the unit runs as intended. Replace a failed board to restore communication between the user controls and mechanical components. What it does:

• Interprets user inputs and sends signals to motors, valves, and heaters
• Controls cycle timing, sensors, and automatic functions
• Commonly linked to symptoms like no power to controls, unresponsive or erratic operation, or cycles that won't start/complete
• Prevents incorrect signals that can cause inconsistent performance

What's included: One main control board assembly as pictured. Install notes:

• Disconnect power (unplug or shut off breaker) before starting any repair
• Handle the board by the edges and avoid static discharge; use anti-static precautions if available
• Note connector locations and take pictures before unplugging wires to ensure correct reassembly
• After installation, restore power and run a diagnostic or test cycle to ensure proper operation
