Is This the Right Part?

Common Symptoms

• Timer will not advance.
• Clock or display does not show.

Check Before Replacing

• Confirm the appliance model is listed for W11544455 before diagnosing or ordering; visually similar boards can differ.
• With the microwave fully assembled and the door closed, note whether the clock/display operates, the timer advances, and a Start command is accepted. These observations can support troubleshooting but do not by themselves confirm a failed control board.
• Disconnect power before any service access; use the appliance model’s technical documentation or a qualified microwave servicer for further diagnosis.
