How to Fix / Troubleshooting

Safety: Unplug the microwave.

Quick checks:

  • Press each button individually and feel for one that does not click or feels stuck.
  • Clean the keypad surface with a slightly damp cloth (no excessive moisture).

Internal steps:

  • Remove the control panel and inspect the keypad ribbon cable and connector.
  • Reseat the ribbon cable and check for bent contacts.

Corrective actions:

  • If a specific key is stuck or always active, replace the membrane keypad or entire control panel assembly.
  • If replacing the keypad does not clear F2, the control board may be misreading the keypad matrix and should be replaced.
