Can a Mini Fridge Explode — (Here’s What You Need to Know)

Refrigerators are considered the savior of humanity. Refrigerators are our best friends throughout the entire year. A refrigerator is considered so helpful that it can store our valuable food stocks and keep them fresh for a long time.


A mini-fridge is the compact version of a regular refrigerator and still does the same job.

A mini-fridge explosion is rare, but they do take place. When a mini-fridge explodes, it threatens to obliterate your entire family. And the worst part of this explosion is that they come without any warning. Most refrigerator explosions have been noticed happening without any warning.

Can a Mini Fridge Catch Fire or Explode?

Since a mini-fridge runs continuously, it increases the chances of any unwanted casualties like your mini-fridge catching on fire or even exploding. There are a couple of factors affecting this trigger in your mini-fridge. They are 10 methods mentioned below:

Capacitor Failure

Many fire accidents have occurred, leading to casualties and asset loss because of damaged wires and improper insulation.

There is a component inside electronic devices called a capacitor. A capacitor is a technical component that stores electricity in an electronic device. The capacitor distributes the electrical power to a compressor without any imbalances.

Various sorts of stress are applied to a capacitor. Overvoltages, overheating, humid conditions, and radiation are pivotal factors for the rapid aging of any electrical device like a refrigerator.

The light bulb left on

If the light bulb which comes pre-installed with your mini-fridge fails, replacing it with a different light bulb can cause a problem. For example, there could be a shortage of wattage, or the light bulb quickly heats your mini-fridge. As a result, the conductor may reach a higher temperature and ignite a fire.

Overload Shield and Overheating Controller

The relay or the overload protector, which is driven by water drip from the dispenser tray, these electrical components can cause a fire in the fridge. It could cause an electrical short circuit, resulting in a fire. The windings of the relay loop can break down, causing intense heating and possibly a fire.

Malfunction of the Fan motor

One of the major components of a fridge are evaporator and condenser. The motors used in these devices have compact copper wiring.

As a result, they might produce excessive heat and trigger a fire. In addition, these fan motors can get dusty, and fan covers are full of debris, slowing down their rotation speed. 

Compressor Malfunction

Without proper ventilation, the compressor of the mini-fridge could lead to overheating. This is a universal cause of fire triggers in electronic devices.

A compressor is not configured to have its cooling system, and heat issues can cause a fire. A defective compressor could cause an electrical short circuit and, ultimately, a fire. 

Defrost Failure

A defrost regulator alternates the chilling and defrosts cycles in the refrigerator. In addition, it allows for the automatic defrosting of the evaporator coils.

However, water can gather in the device housing and penetrate the defrost switch box, forming a route between the defrost section contacts and producing heating in most cases.

As a result of the heating, a gas vapor is released, which might collect in the compartment and ignite.


Cyclopentane is used in fridges. Cyclopentane is extremely flammable and causes fire occurrence. When a flame occurs, it is hard to control.

Voltage Fluctuations

Energy fluctuations are most common and happen frequently. It is one of the significant causes of fire occurrence in houses. When there is a high voltage, it can increase the chances of a spark. Sparks can lead to ignition fire.

Refrigerants Issues

Compared to prior non-flammable coolants, the present refrigerant uses extremely flammable isobutane and propane.

As a result, there is a risk when there is a leakage. For example, a refrigerant circuit malfunction can cause gas to leak, leading to a fire by a spark. In addition, the refrigerant seal can deteriorate and be damaged. This can result in flammable refrigerant gas escaping and igniting by a spark.

Manufacturing Defaults

There is another unchangeable cause for this: human error or a manufacturing error. Industrial errors, such as component disparities, are inevitable. And this has already resulted in several product recalls.

Can a Refrigerator Compressor Explode

Since a compressor is an integral part of your mini-refrigerator, it is also a highly sensitive part. Unfortunately, such vital aspects can trigger a lot of problems. 

When the gas refrigerant runs through the mini-fridge, it causes the mini-fridge to heat up at a greater rate. It causes the compressor coil to contract by trapping the flammable gas. The gas gets trapped, and this causes the gas to burst out of the chamber. 

How to Prevent Fridge Blast

Since a fridge is an essential appliance of your house, maintenance is necessary. Cleaning around all the electrical components of a refrigerator is important.

But if you are still concerned about your mini-fridge, it’s best to contact the manufacturers for proper maintenance. You can take more steps to prevent the fridge from a blast.

Dedicated slot

Since your fridge will be running nonstop, it is better to have a dedicated slot for your refrigerator. It will save your fridge from unnecessary Voltage fluctuations and let your fridge run smoothly. Also, running multiple devices from one single power out will increase the chances of a fire.

Power plug

When placing your power plug, be cautious. Your fridge’s chances of catching fire will grow if you’re not vigilant. Water might fall into the plug and cause it to fail. The power plug, too, can be harmed. Both of these will result in a fire.

Power plug condition

Inserting the plug into the socket should be done with caution. Water and dust collect on the pins from time to time, as you can see. They need to be cleaned. Use a clean, dry cloth to wipe them down. Once they’ve been cleaned, reinstall them in the socket properly and tightly.

Power supply cord

An unintentional fire will result from a damaged cord. If the cord is damaged, you can potentially get an electric shock if you contact it. Purchase a heavy-duty power cord that will provide you with the best protection possible.

Earthing and grounding

The importance of grounding and earthing cannot be overstated. You will have grounding if you are living in an apartment. However, while taking possession of the unit, inquire of the builder.

If you built your own home, consult an engineer. These have the potential to ignite a fire if the grounding is damaged.

Can an Unplugged Fridge Explode

No. There is no record of an unplugged fridge exploding in the past. When there is no power in your refrigerator, your refrigerator will not explode.

There have to be issues like heating, leaking, or parts failure for a refrigerator to explore. Without your fridge running, it will not cause you any harm.


Clean your refrigerator’s coils to avoid a fridge explosion in your own home to make sure they aren’t clogged. Modern refrigerators typically have a heat shield to avoid this, but some types, particularly older ones, contain highly flammable plastic and may lack other current safety precautions.
