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.
Pro Tip
Do not identify this board by appearance alone: verify the microwave’s complete model number and the W11544455 part number, because similar-looking boards may differ.
