Microwave clock and settings reset every time the door is opened or when starting a cycle.

Safety first: Unplug before internal inspection.

• Step 1 – Check power connection: Ensure the plug fits firmly in the outlet and that no extension cord is used.
• Step 2 – Test another outlet: Plug the microwave into a different, known-good outlet.
• Step 3 – Observe when reset occurs: If resets happen exactly when the door moves, a shorted door switch or wiring may be causing a momentary power drop.
• Step 4 – Professional diagnosis: A technician should inspect the door switch wiring, line filter, and control board power supply, replacing the faulty component.
