Microwave has a burning smell during or after use, even when no food is burning.

Safety first: If you see smoke or flames, stop the microwave immediately, keep the door closed, and unplug the unit.

• Clean thoroughly: Remove all food splatter and grease from the cavity, ceiling, and waveguide cover.
• Run with water: After cleaning, run the microwave with a large cup of water for several minutes to help clear residual odors.
• Inspect externally: Check for discoloration or heat marks on the cabinet or around vents.
• Stop use if smell persists: Persistent burning smells without visible residue may indicate internal component overheating and should be investigated by a technician.
