Description

As the appliance's electronic brain, this main control board manages power and coordinates components. Replacing a failed board restores proper power distribution and communication so the unit powers on, responds to inputs, and operates reliably. What it does:

• Distributes power and controls motors, valves, heaters, fans, lights, and other loads
• Interprets signals from sensors and user inputs to run the correct program
• Common symptoms of a failed board: no power/display, unresponsive controls, won't start, intermittent shutdown, or error codes
• Also cause erratic behavior such as random beeps or relays clicking

What's included:

• 1 main control board (PCB assembly)

Install notes:

• Disconnect power at the breaker or unplug the appliance before servicing
• Use ESD protection and handle the PCB by the edges
• Photograph wiring and move connectors one at a time to the new board; ensure keyed orientation and full seating
• Secure the board in its housing/bracket, restore power, and follow model-specific service instructions to test operation
