If you notice a burnt or smoky smell coming from the Mijia Refrigerator Side-by-Side 635L, it is important to act immediately to ensure safety. First, unplug the refrigerator from the power outlet to cut off the electrical supply. Do not attempt to continue using the appliance, as the smell can indicate an electrical fault or overheating component inside the refrigerator. Avoid opening or touching internal parts on your own, as this could be dangerous. Once the refrigerator is powered off, contact the after-sales service center promptly to request a professional inspection and repair. Professional technicians will be able to identify the source of the burnt smell, ensure that there is no risk of fire, and restore the refrigerator to safe and normal operation.
