Simple Fixes For A Freezer That’s Not Freezing
Freezers are dependable appliances in the kitchen, ensuring that our food remains preserved and fresh for extended periods. However, there may be instances where your freezer stops freezing, leaving you puzzled and concerned about the state of your food. Thankfully, there are simple fixes that can help resolve this issue without the need for professional assistance.
Firstly, it is important to check the temperature control thermostat. A faulty thermostat can cause the freezer to run constantly, preventing it from reaching the desired freezing temperature. You can try adjusting the thermostat to a cooler setting to see if that solves the problem. If not, you may need to replace the thermostat.
Another common culprit for a freezer not freezing properly is a malfunctioning fan motor. The fan is responsible for circulating cold air throughout the freezer, so if it is not functioning correctly, the temperature may not reach the desired level. Inspect the fan motors and replace any that show signs of damage or wear.
Furthermore, strange sounds coming from your freezer may indicate underlying issues. Dirty condenser coils, for example, can cause the freezer to make unusual noises and prevent it from functioning optimally. Cleaning the condenser coils regularly can help prevent heat retention and ensure efficient cooling.
Understanding How Freezers Work
To better comprehend why a freezer may stop freezing, it is essential to understand how these appliances work. Most freezers operate using a cooling pipe filled with liquid coolant, typically a refrigerant gas.
The compressor plays a crucial role in the freezing process. It compresses the refrigerant gas, increasing its temperature and pressure. As the gas flows through the condenser coils, it dissipates heat and transforms into a high-pressure liquid. This liquid then passes through an expansion valve, where it quickly expands and evaporates into a low-pressure gas.
This evaporation process absorbs heat from the freezer’s interior, thus lowering its temperature. The cold gas travels back to the compressor to continue the cycle, ensuring a consistently cold environment within the freezer.
Key points:
- Freezers use a cooling pipe filled with refrigerant gas.
- The compressor increases the temperature and pressure of the gas.
- The condenser coils dissipate heat, transforming the gas into a high-pressure liquid.
- The expansion valve causes the liquid to evaporate into a low-pressure gas, absorbing heat from the freezer’s interior.
- The cold gas returns to the compressor to maintain the cold environment.

Common Freezer Problems And Their Causes
Despite being reliable appliances, freezers can encounter various problems that hinder their freezing capabilities. One common issue is a freezer running constantly, which can be attributed to a faulty temperature control thermostat. When the thermostat fails, it fails to regulate the temperature effectively, causing the freezer to continuously run in an attempt to reach the desired cooling level.
Another problem that may arise is strange sounds coming from the freezer. This could be due to dirty condenser coils, obstructing the cooling process and causing the freezer to work harder than intended. A faulty evaporator fan can also result in unusual noises, indicating a need for repair or replacement.
Additionally, a freezer that is not freezing may produce loud buzzing or clicking sounds and may run less cold than usual. In such cases, it is essential to check for a clogged or frozen defrost drain, as this can impede the freezer’s ability to maintain its freezing temperature. The defrost drain can often be unclogged simply by using hot water.
Moreover, improper sealing of the freezer door can also lead to a freezer not freezing correctly. Poorly installed or old door seals can allow cold air to escape, resulting in a drop in temperature. Testing the door by placing a piece of paper or a dollar bill can help determine if the seals need repairing or replacing.
Troubleshooting Tips For Freezer Malfunctions
When faced with a freezer that is not freezing, it is essential to follow proper troubleshooting steps to identify and resolve the issue.
Begin by ensuring that there is enough space under the evaporator fan for proper circulation of cold air. Poor packing of freezer contents can obstruct the fan’s airflow, preventing the entire freezer from reaching its desired temperature.
Regularly cleaning the condenser coils is also crucial to maintain the freezer’s cooling capacity. Dust and debris accumulation on the coils can impede the heat dissipation process, causing the compressor to overcompensate and reducing the efficiency of the freezer.
Additionally, malfunctions in internal components, such as the evaporator fan, can hinder the freezing process. Regularly check and clean fan blades, and inspect for any broken wires that may be affecting its performance.
If all else fails, it may be necessary to conduct a physical test of the start relay, especially if the freezer is not freezing at all. Unplugging the refrigerator and checking the start relay’s functionality can help determine if it is the cause of the problem.
- Ensure enough space under the evaporator fan for proper airflow
- Regularly clean the condenser coils to maintain cooling capacity
- Check and clean fan blades, inspect for broken wires
- Conduct a physical test of the start relay if all else fails
If the freezer is still not freezing, it is best to consult a professional technician for further assistance.
