| Error Code | Description | Cause | Solution |
|---|---|---|---|
| E1 / E2 | Temperature Sensor Error | Faulty temperature sensor or overheating. | Turn off the oven and unplug it. Allow the microwave to cool down for a few minutes, then plug it back in. If the error persists, it may need sensor replacement. |
| E3 | Door Not Closed Properly | Door is not fully closed or has a defective latch. | Open and close the door firmly. Check for obstructions around the latch. If the error remains, the door latch assembly might need repair. |
| E4 | Power Supply Issue | Inconsistent or insufficient power supply. | Make sure the oven is plugged into a dedicated power outlet and not an extension cord. Check for any loose connections or voltage fluctuations. If the issue continues. |
| E5 | Communication Failure | Internal control board malfunction. | Unplug the microwave, wait a few minutes, and plug it back in. If the error does not clear. |
| E6 | Magnetron Overheating | The magnetron, which heats the microwave, has overheated. | Turn off the oven and let it cool down. Ensure the air vents are not blocked. If the problem persists, the magnetron might require replacement. |
| E7 | Humidity Sensor Malfunction | Humidity sensor is faulty or clogged. | Wipe any condensation or debris around the sensor. If that doesn’t help, the sensor may need replacement. |
| E8 | Turntable Motor Error | The turntable motor is jammed or defective. | Remove any heavy or unevenly placed items on the turntable. Ensure it spins freely. If it’s stuck or still not working, consult for motor replacement. |
| E9 | Fan Failure | Cooling fan is not working properly. | Ensure the microwave vents are clean and unobstructed. If the fan still isn’t functioning, you may need a technician to replace it. |
If any error codes reappear frequently or do not clear after following these steps, it’s recommended to contact Prestige customer support or a qualified repair technician.
