Microwave displays E14 and the clock resets or the unit randomly powers off and on.

Safety first: Unplug the microwave before internal inspection.

• Step 1 – Check outlet and plug: Ensure the plug is fully inserted and the outlet is not loose. Try a different outlet if possible.
• Step 2 – Avoid shared high-load circuits: Do not run the microwave on the same circuit as heavy appliances (dishwasher, refrigerator) that may cause voltage dips.
• Step 3 – Inspect power cord: Look for damage or kinks in the cord. Replace if any damage is found.
• Step 4 – Internal line filter: With the cover removed and power disconnected, inspect the line filter module and its connections. Tighten any loose spade terminals and look for burn marks.
• Step 5 – Replace line filter or control board: If the line filter is defective or if the main relay on the control board is intermittent, replace the faulty component.
