Microwave produces a strong burning or electrical smell during or after use.

Safety first: Unplug the microwave immediately if the smell is strong or accompanied by smoke.

• Inspect interior: Look for burnt food, especially under the turntable, on the ceiling, and near the waveguide cover. Clean thoroughly.
• Check waveguide cover: If the cover is darkened or burnt, replace it.
• External inspection: Remove the outer cover and look for discolored or melted wiring, especially near the magnetron and transformer. Do not touch HV components.
• Do not continue use: If the smell persists after cleaning, a component may be overheating. Have the unit inspected by a technician or replace the microwave.
