What to do if my Samsung CM1619 Microwave Oven shows E3 error?
- JJames JonesSep 6, 2025
If your Samsung Microwave Oven displays error code E3, it could be due to overheating inside the cavity because there's no load or too little load. Try plugging the power cord in again. Also, check for any blockages around the air exhaust area or ventilation openings. If the error persists, check the resistance of the Thermistor sensor and replace it if defective. The ventilation motor might be failing and causing the magnetron to overheat; replace the motor if necessary.
