When to call a technician
If the code persists, the keypad or door switch needs replacing.
If those checks don't clear the F-3E / F-7E code, it's usually a sign of a failed part rather than something to keep resetting. A technician runs a full diagnostic on your microwave, confirms the cause, and quotes the repair before any work starts. The $89 service call is waived if you go ahead with the repair, and parts and labor are covered by our 90-day warranty on parts & labor.
