Why do refrigerators explode, and how can it be prevented

The main causes of refrigerator compressor explosions usually stem from a few key issues.
If there is an electrical short circuit or wiring problem, excess current can flow, causing the compressor to overheat. This increases internal pressure and may lead to an explosion.
 

Gas leakage or overfilling with refrigerant can also create abnormal pressure inside the compressor. If the temperature rises too high, an explosion may occur.

Thirdly, chemical reactions between oil and gas inside the compressor (such as using impure or counterfeit refrigerant) can create flammable conditions. If there is a ventilation problem inside the compressor or if the cooling fan stops working, heat can build up — increasing the risk of an explosion.

To prevent refrigerator compressor explosions, certain precautions should be followed:
 

• Ensure that voltage fluctuations do not damage the compressor.
   

• Always use approved and correct types of refrigerant, as counterfeit or wrong types can create abnormal pressure and increase the risk of explosion.
   

• Regular servicing and maintenance should be done to detect gas leaks, electrical wiring issues, and the general condition of the compressor early on.
   

• The refrigerator’s wires or plugs should never be damaged or loose, as this can lead to short circuits.
   

• Ensure there is proper airflow around the compressor to prevent heat buildup.
   

• Avoid overfilling gas through untrained technicians, as this can increase pressure and cause an explosion.
   

• The refrigerator should always be placed on a level surface to prevent abnormal pressure inside the compressor.
