Microwave emits a burning smell, electrical odor, or smoke during or shortly after operation.

Safety: Immediately stop the microwave, unplug it, and open windows for ventilation. Do not continue using the unit until the cause is identified.

• Inspect interior: Check for burned food, packaging, or grease on the cavity walls, ceiling, and floor. Clean thoroughly with a microwave-safe cleaner.
• Check accessories: Ensure no metal objects, twist ties, or non-microwave-safe containers were used.
• Smell test (carefully): After cooling, remove the outer cabinet and visually inspect wiring, the magnetron, and the control board for burn marks or melted insulation.
• Do not operate if damage found: If any components show signs of burning, have a Viking-authorized technician replace the damaged parts (magnetron, wiring harness, control board, etc.).
• Preventive cleaning: Regularly clean the grease filters and interior to prevent future odors and overheating.
