This electronic control board manages and sequences the appliance's functions, user controls and display so cycles run correctly and settings respond. It restores electronic control when the original board is failed or unresponsive. What it does

• Receives input from the control panel and directs power to the appropriate components to start and run cycles.
• Controls timers, cycle selection, and electronic displays so programmed operations complete as expected.
• Common symptom linkage: unresponsive buttons or display, cycles won't start or complete, or intermittent operation tied to control faults.
• Replaces a failed control board to restore reliable electronic control and consistent cycle performance.

• One electronic control board.

• Disconnect power (unplug or shut off breaker) before any service to avoid shock hazard.
• Handle the board by the edges and avoid touching contacts; observe basic static-discharge precautions.
• Installation typically requires removing the control panel or console and disconnecting wiring harnesses—keep track of connector locations.
