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

Safety first: If you smell burning plastic or insulation, stop the microwave immediately, unplug it, and do not use it until inspected.

Steps:

• 1. Check for burnt food: Inspect the interior for overcooked food, splatters, or spills on the cavity walls, ceiling, and turntable. Clean thoroughly.
• 2. Run a short test: After cleaning and cooling, heat a cup of water for 30–60 seconds. If the burning smell returns quickly, an internal component is likely overheating.
• 3. Internal inspection (experienced DIYers): Remove the cabinet and look for discolored or melted wiring, especially near the magnetron, fan motor, and control board connectors.

Recommendation: If any wiring or components show signs of overheating, have them replaced by a professional. Do not continue using the microwave until repaired.
