How to Fix / Troubleshooting
Safety first: Do not open the microwave cabinet yourself.
User-level checks:
- Power level: Confirm the power level is set to HIGH (10) and not a lower setting.
- Standard test: Heat 1 cup of room-temperature water on HIGH for 2 minutes. It should be very hot or boiling. If only warm, heating power is reduced.
- Check outlet: Avoid using long extension cords; plug directly into a dedicated outlet to ensure proper voltage.
- Service: A technician should measure output power and test the magnetron, capacitor, and inverter/transformer, replacing any weak components.
