A hot compressor on a refrigerator is not likely to cause an explosion. It is normal for a refrigerator's compressor to get warm during operation, as it is the component responsible for compressing the refrigerant gas to remove heat from the inside of the fridge and maintain a cool temperature.
However, if the compressor is extremely hot to the touch or emitting a burning smell, it could be a sign of a problem that needs attention. Several issues could lead to an overheating compressor, such as a malfunctioning condenser fan, blocked ventilation, or a fault in the compressor itself. If the compressor is overheating, it may not be functioning efficiently, which can impact the refrigerator's cooling performance.
In extreme cases, an overheating compressor could potentially lead to a failure or malfunction, but it is unlikely to cause an explosion. If you notice your refrigerator's compressor is excessively hot or suspect any issues, it is essential to have it checked by a professional appliance repair technician. They can diagnose the problem and make the necessary repairs to ensure your refrigerator operates safely and efficiently.
