Refrigerators can explode due to several factors, including improper placement and usage. Placing a refrigerator too close to heat-generating devices like stoves or microwaves can cause overheating or short-circuiting, leading to an explosion. Similarly, positioning electrical wires near combustible materials like curtains or blankets increases the risk of fires.

Using an old or poorly maintained refrigerator is another common cause. Old models with clogged capillary tubes, excessive dirt, or frequent repairs can overheat and malfunction. Signs of an at-risk refrigerator include continuous compressor operation, loud noises, excessive ice buildup, and poor cooling. Regular maintenance or replacement is advised.

Storing carbonated drinks, alcohol, or glass bottles in the freezer can also be hazardous. These items can expand or contract due to temperature changes, leading to explosions. Additionally, gas leaks combined with electrical issues pose significant risks. If a gas leak occurs and an electrical short circuit sparks, the refrigerator could catch fire, especially if the electrical system is overloaded.

Lastly, plugging multiple devices into the same outlet or using chemicals like insect repellents near the refrigerator can create sparks, increasing the likelihood of a fire or explosion. Regular maintenance and cautious usage can help mitigate these dangers.
