Kenmore Microwave F9 Error Code — Door Latch Fault

Kenmore Microwave

High Severity
Warning: If your Kenmore appliance displays the F9 error code and you are unsure how to proceed, turn off the appliance and contact a qualified technician. Some errors require professional repair to avoid further damage or safety risks.

The F9 error code on a Kenmore microwave indicates the door latch assembly is not functioning correctly. The control board has detected an inconsistency in the door switch status signals — the switches are not all reporting the same state simultaneously as expected.

Causes

  • Worn or broken door latch hooks
  • Door switch out of alignment
  • Damaged door strike (receiver plate)

What To Do

  1. Inspect the door latch hooks (on the door) and the strike openings (on the microwave body) for cracks or wear.
  2. Do not attempt to operate the microwave with F9 — the door safety system is compromised.
  3. Professional repair or door assembly replacement is required.
