Freezers are an essential appliance in every household, allowing us to keep our food fresh and avoid frequent grocery trips. However, like any other electrical appliance, freezers can sometimes stop working unexpectedly. If this happens, it can be frustrating and potentially result in the loss of all your stored food.
There are several factors that can cause a freezer to stop working. One common cause is a power outage. If the freezer is not receiving electricity, it will not be able to maintain the required temperature to keep your food frozen. In such cases, it is important to check if there are any issues with the power supply or if there is a power outage in your area.
Faulty or blocked condenser coils can also be a reason for a freezer to stop working. Condenser coils are responsible for removing heat from the freezer. If they become dirty or blocked with dust, the heat exchange process is hindered, and the freezer can’t cool properly. Regular cleaning and maintenance of the condenser coils can help prevent this issue.
In addition, a malfunctioning thermostat can cause a freezer to stop working. The thermostat controls the temperature inside the freezer and signals the compressor to turn on and off accordingly. If the thermostat is not functioning correctly, it may not signal the compressor to turn on, resulting in a warm freezer. In this case, seeking professional help to replace or repair the thermostat is recommended.
Furthermore, a faulty compressor or a refrigerant leak can also lead to a freezer malfunction. The compressor is responsible for compressing the refrigerant and circulating it through the coils. If the compressor is damaged or the refrigerant levels are low due to a leak, the freezer will not be able to cool properly. An experienced technician can diagnose and fix these issues to restore your freezer’s functionality.
Possible Causes of a Non-Functioning Freezer
When your freezer stops working, it can be frustrating and potentially costly if your food starts to spoil. There are several possible causes for a non-functioning freezer, including:

If you suspect a thermostat malfunction, it is essential to have it inspected and repaired by a qualified technician. They can diagnose the issue and replace the thermostat if necessary.
Regular maintenance and cleaning of the freezer, including checking the thermostat, can help prevent malfunctions and prolong the lifespan of the appliance.
Defective Start Relay
A defective start relay is another possible cause for a freezer to stop working. The start relay is responsible for initiating the compressor’s start-up process. If the start relay is defective, it may not be able to provide the necessary power to start the compressor. This can result in the freezer not cooling properly.
If you suspect that the start relay is defective, you can test it with a multimeter. First, unplug the freezer and locate the start relay, which is usually located near the compressor. Remove the protective cover and carefully disconnect the wires connected to the start relay.
Using a multimeter set to the resistance or continuity mode, touch one probe to each terminal on the start relay. If the multimeter reading shows infinite resistance or there is no continuity, this indicates a faulty start relay that needs to be replaced.
Replacing the start relay is a relatively simple process. Obtain a new start relay that is compatible with your freezer model. Carefully connect the wires to the new start relay, making sure to connect them to the correct terminals. Replace the protective cover and plug the freezer back in to see if the issue has been resolved.
If replacing the start relay does not fix the problem, it may be necessary to consult a professional technician for further diagnosis and repair.
Faulty Compressor
If your freezer has suddenly stopped working, one possible cause could be a faulty compressor. The compressor is a vital component of a freezer, as it is responsible for circulating the refrigerant and maintaining the correct temperature.
A faulty compressor can cause your freezer to stop working altogether or fail to maintain the desired temperature. There are several reasons why a compressor may fail:
1. Overloading
If you overload your freezer by storing excessive amounts of food or placing hot items inside, it can put excessive strain on the compressor. Over time, this can lead to compressor failure.
2. Power surges
Power surges, which occur when there is a sudden increase in electrical voltage, can damage the compressor. These surges can be caused by lightning strikes or faulty electrical wiring in your home.
In some cases, a faulty compressor may exhibit warning signs before it completely stops working. These signs can include loud noises coming from the freezer, such as clicking sounds or a buzzing noise that indicates the compressor is trying to start but cannot.

Clogged Condenser Coils
One common issue that can cause a freezer to stop working is clogged condenser coils. The condenser coils are responsible for releasing heat from inside the freezer to the outside environment. However, over time, these coils can become clogged with dust, pet hair, and other debris. When this happens, the coils cannot effectively release heat, which can lead to the freezer overheating and shutting down.
To prevent clogged condenser coils, it is important to regularly clean them. This can be done by using a vacuum cleaner with a brush attachment to gently remove any dust or debris. It is recommended to perform this cleaning task at least once every six months, or more frequently if you have pets that shed a lot of hair.
If you notice that your freezer is not cooling properly or is completely not working, check the condenser coils for any signs of clogging. If they appear dirty, try cleaning them as described above and see if it improves the freezer’s performance. However, if cleaning the coils does not resolve the issue, it may be necessary to contact a professional technician to further diagnose and repair any underlying problems.
Evaporator Fan Problems
One common cause of a freezer stopping to work is problems with the evaporator fan. The evaporator fan is responsible for circulating the cold air throughout the freezer and helps maintain a consistent temperature.
If the evaporator fan fails, it can result in the freezer not cooling properly. This can be caused by a faulty motor, a blocked or frozen fan blade, or a malfunctioning fan switch. If the motor is not working, the fan will not be able to spin and circulate the cold air. If the fan blade is blocked or frozen, it will not be able to move the air effectively. And if the fan switch is malfunctioning, it may not turn on the fan when needed.
To diagnose and fix evaporator fan problems, you can start by checking if the fan is spinning when the freezer is running. If it’s not spinning, you may need to replace the fan motor. If the fan blade is blocked or frozen, you can try defrosting it by turning off the freezer and letting it melt. Clean any debris that may be blocking the blade and ensure it is able to move freely. If the fan switch is not working, it may need to be replaced with a new one.
| Common Evaporator Fan Problems | Possible Solutions |
|---|---|
| The fan is not spinning | Replace the fan motor |
| The fan blade is blocked or frozen | Defrost the blade, clean any debris, ensure free movement |

It’s important to address evaporator fan problems promptly to prevent further damage to the freezer and ensure it continues to work efficiently. If you are unsure how to diagnose or fix the issue, it is recommended to consult a professional technician.
Frost Build-up
One common cause of a freezer not working is a frost build-up. When frost accumulates inside the freezer, it can interfere with the proper functioning of the cooling system. This build-up can be caused by several factors:
Poor Door Seal
A defective or worn-out door seal can allow warm air from the surrounding environment to enter the freezer. When this humid air comes into contact with the cold surfaces inside, it condenses and freezes, leading to frost build-up. Inspect the door seal for any visible damage and replace it if necessary. To test the seal, close the door on a piece of paper or dollar bill and try to pull it out. If it slides out easily, the seal may need to be replaced.
Open Doors or Overloading
Leaving the freezer door open for extended periods or frequently opening and closing it can introduce warm air into the unit. This can cause frost to form on the cold surfaces. Additionally, overloading the freezer with too much food can restrict airflow and prevent proper cooling, increasing the likelihood of frost build-up. Ensure that the doors are always fully closed and avoid overcrowding the freezer.
| Problem | Possible Causes |
|---|---|
| Frost build-up | Poor door seal, open doors or overloading |
| Defective defrost system | Faulty defrost timer, defrost heater, or defrost thermostat |
| Faulty temperature control | Misadjusted thermostat or malfunctioning temperature control board |
| Power supply issues | Tripped circuit breaker, damaged power cord, or malfunctioning outlet |
| Faulty compressor | Compressor motor failure or low refrigerant levels |
If you notice frost build-up in your freezer, it is important to address the issue promptly. Excess frost can restrict airflow and lead to further cooling problems. Regularly defrosting the freezer and keeping the door seal in good condition can help prevent frost build-up and maintain the efficient operation of your freezer.
