Why is Your Freezer Not Working While the Fridge is Fine?

When it comes to home appliances, a malfunctioning freezer can cause a great deal of concern. It can lead to food spoilage and inconvenience for the entire household.

One common issue that homeowners encounter is when the freezer stops working, but the fridge continues to operate normally.

In this article, we will explore the possible causes and solutions for a freezer not working while the fridge is fine.

We will discuss five common reasons for this problem and provide helpful tips on troubleshooting and maintenance to prevent further damage.

By understanding these issues, you can take the necessary steps to fix the problem or seek professional help when needed.

1. Air Leaks

One of the most common causes of a freezer not working while the fridge is fine is the presence of air leaks.

You may notice that the entire freezer compartment has frost buildup, and it doesn’t maintain a cold enough temperature to keep ice cream fully frozen.

This indicates that warm air is leaking into the refrigerator, causing food to spoil faster.

To check for air leaks, inspect all door gaskets and replace any damaged ones.

If the freezer door slumps on its hinges, it can create gaps between the gasket and the door openings, allowing warm air to enter.

Adjust the door hinges to ensure the door is properly locked in place and no warm air can get through.

2. Defective Automatic Defrost System

Another potential reason for a freezer not working while the fridge is fine is a defective automatic defrost system.

Under normal circumstances, the defrost system melts frost every 8 hours from the evaporator coils.

If you notice an unusual buildup of frost on the back compartment wall and evaporator coils, cool air will not be able to pass through the air paths, resulting in insufficient cooling in the freezer.

If you suspect a malfunctioning defrost system, it is best to replace the defrost heater, defrost sensor, or other components related to the defrost system in your refrigerator.

This will ensure that the frost is properly melted and the cooling process is restored.

3. Busted Evaporator Fan

The evaporator fan plays a crucial role in distributing cool air into both the freezer and the refrigerator.

It should turn on as soon as the compressor starts running.

However, if you notice that the evaporator fan is not functioning, there may be a problem with the wiring or electronic control board.

Faulty wiring can cause the fan to malfunction and disrupt the cooling process.

To diagnose this issue, it is important to ensure the refrigerator is unplugged for safety.

Use a multimeter to check the wiring and electronic control board for any abnormalities.

If the wiring is faulty or the fan does not run even after repairs, it is recommended to replace the evaporator fan to restore proper cooling.

4. Dirty Condenser Coils or Faulty Condenser Fan

Dirty Condenser Coils or Faulty Condenser Fan

Dirt and dust accumulation on the condenser coils can significantly impact the cooling capacity of your freezer.

Regularly cleaning these coils as part of your maintenance routine is essential to keep your refrigerator working optimally.

Failure to clean the coils can lead to reduced cooling efficiency and potential damage to the compressor.

Similarly, a faulty condenser fan can also contribute to inadequate cooling in the freezer.

The condenser fan is responsible for dissipating heat from the condenser coils, allowing the refrigerant to cool effectively.

If the fan is not functioning correctly, the refrigerant will not cool efficiently, resulting in poor freezer performance.

To resolve these issues, unplug the refrigerator before cleaning the condenser coils to avoid accidents.

Use a brush or vacuum cleaner to remove dirt and dust.

If you find that the condenser fan is not running when activated, it is necessary to replace the faulty fan to restore proper cooling.

5. Defective Temperature Sensors

Defective temperature sensors or thermistors can also cause a freezer to stop working while the fridge remains operational.

These sensors provide information to the electronic control board, allowing it to monitor and regulate the cooling process.

If the sensors are malfunctioning, the control board may receive incorrect signals, leading to either excessive cooling or insufficient cooling in the freezer.

To diagnose this issue, unplug the refrigerator for safety and check for any wiring damages or loose connections.

If the wiring appears to be in good condition, use a multimeter to test the resistance of the thermistor.

Place the thermistor in a cup of ice water and measure the resistance.

Typically, the resistance should be around 27,000 ohms at a water temperature of approximately 32 degrees Fahrenheit.

Any significant deviation from this reading indicates a defective temperature sensor.

If you encounter a faulty temperature sensor, it is recommended to replace it to ensure accurate temperature regulation in both the freezer and the fridge.

Maintenance Tips to Prevent Freezer Issues

Safety Tips for When Freezer Not Working but Fridge Is

Preventive maintenance is key to avoiding freezer problems and maintaining the durability of your refrigerator.

Here are some essential maintenance tips to keep your freezer in optimal working condition:

  1. Regularly clean the condenser coils to remove dirt and dust buildup.
  2. Check and replace damaged door gaskets to prevent air leaks.
  3. Adjust door hinges to ensure a proper seal and prevent warm air infiltration.
  4. Monitor the frost buildup in the freezer and promptly address any irregularities.
  5. Inspect and clean the evaporator fan to ensure proper airflow.
  6. Follow the manufacturer’s instructions for the defrost system and replace components as needed.
  7. Check and test temperature sensors periodically to ensure accurate temperature regulation.

By incorporating these maintenance practices into your routine, you can minimize the risk of encountering freezer issues and prolong the lifespan of your refrigerator.


When faced with a freezer not working while the fridge is fine, it is important to identify the underlying causes and take appropriate measures to address them.

Air leaks, defective automatic defrost systems, busted evaporator fans, dirty condenser coils or faulty condenser fans, and defective temperature sensors are common culprits behind this problem.

By understanding these issues and following proper maintenance practices, you can prevent freezer malfunctions and ensure the optimal performance of your refrigerator.

However, if troubleshooting efforts do not resolve the problem, it is advisable to consult a professional technician to avoid further damage and ensure the long-term functionality of your appliance.
