Microwave runs for a few seconds then stops and resets or goes back to clock display.

Safety: Unplug before internal inspection.

Steps:

• 1. Check power connection: Ensure the plug fits tightly in the outlet and the cord is not loose or damaged.
• 2. Test with different outlet: Try another properly grounded outlet to rule out supply issues.
• 3. Inspect door switches: A loose or misaligned door switch can open briefly during operation. Check the switch bracket and replace any worn switches.
• 4. Control board and thermostats: If the unit consistently stops after the same short interval, a technician should test the control board and thermal cutouts.
