Microwave clock or settings reset randomly, or unit loses power intermittently

Safety: Unplug the microwave before inspecting internal wiring.

• Check outlet and plug: Ensure the plug fits snugly in the outlet. Try a different outlet if possible.
• Inspect power cord: Look for kinks, cuts, or signs of overheating. Replace if damaged.
• Internal connections: Remove the cabinet and check the connections at the line filter board and control board. Reseat any loose connectors.
• Board inspection: Look for cracked solder joints, especially at large components like relays and transformers. Board replacement is usually required if found.
• Electrical supply: If multiple appliances on the same circuit show issues, have an electrician inspect the house wiring.
