Microwave beeps repeatedly and displays SE; keypad may act as if a button is being pressed continuously.

Safety first: Unplug the Café microwave or turn off the breaker.

Steps to try:

• Dry the control: If the panel was recently cleaned, leave the door open and allow the control area to dry for several hours.
• Power reset: Restore power and see if SE clears. If it returns immediately, the keypad is likely shorted.
• Inspect ribbon cable: If you can safely remove the control panel, check that the keypad ribbon cable is not pinched or corroded and is fully seated in the control board connector.
• Repair: Replace the keypad or full control panel assembly specific to your Café model. This is typically the long-term fix for SE errors.
• Technician recommended: Because the control panel is near live wiring, have a professional perform the replacement if you are not experienced.
