A warm refrigerator with a cold freezer is a common problem but confusing issue. This common problem can cause food to spoil and lead to frustration. Even though refrigerators and freezers look simple, they use a complex system of parts to keep things cold. Knowing why this happens and what you can do about it can help you save time, money, and keep your food fresh. In this guide, we will answer one of the common questions for homeowners, “Why is my fridge warm but freezer is working?” We will also provide practical solutions to help you troubleshoot the problem efficiently. By understanding the intricacies of your appliance and following our expert insights, you can ensure that both your fridge and freezer are working optimally, keeping your food fresh and safe for consumption. Let’s dive in!
Understanding Why Your Fridge Is Warm While the Freezer Is Cold
Refrigerators and freezers may seem simple, but they depend on careful airflow and temperature control. They have different parts that must work well together. If something goes wrong, the refrigerator can get warm while the freezer keeps working as it should.
The most common reasons for this problem usually involve issues with the parts that move cold air from the freezer to the refrigerator. There may also be problems with the refrigerator’s ability to hold the cold air it gets.
1. Faulty Evaporator Fan
The evaporator fan is very important for moving cold air in your refrigerator. It is found in the freezer compartment. This fan takes cold air from the evaporator coils and spreads it to both the freezer and the fridge.
If the evaporator fan stops working, the airflow gets disrupted. Problems like a broken motor, damaged blades, or ice buildup can stop the fan from sending out cold air properly. This can lead to a warm refrigerator, even when the freezer stays cold. This happens because the evaporator coils are mostly in the freezer compartment.
If you think the evaporator fan is the problem, it’s a good idea to call a professional appliance repair technician. They can check if the fan motor needs to be replaced or if other problems are affecting its function.
2. Blocked Defrost Drain
A warm refrigerator can often be caused by a blocked defrost drain. This drain is important because your fridge’s defrost system melts the frost that builds up on the evaporator coils. The meltwater then goes through the drain and into a pan to evaporate.
If this drain gets clogged with food bits, ice, or dirt, the water can back up. This backup can create too much frost on the evaporator coils. When that happens, it restricts airflow and stops the fridge from cooling properly.
Although a blocked defrost drain may seem small, it can greatly affect how well your fridge cools. Checking and cleaning the defrost drain regularly can help prevent this issue. This will keep your refrigerator at the proper temperature.
3. Malfunctioning Damper Control
The damper control, or air damper, manages how cold air moves from the freezer to the fridge. It is a small door or flap that opens and closes to control cold air entering the refrigerator.
If the damper control does not work right, it can upset the balance of cold air. When the damper is stuck closed, cold air cannot reach the fridge. This makes the refrigerator warm, even though the freezer is fine.
On the other hand, if the damper is stuck open, it can make the fridge too cold and can cause freezing problems. Testing the damper control is important. It should open and close properly to keep the right temperature between the freezer and fridge.
4. Dirty Condenser Coils
Condenser coils are located at the back or bottom of your appliance. They are important because they help release heat from the refrigerant as it moves through the system. If dust, pet hair, or debris build up on these coils, it forms a layer that stops heat from escaping well.
When this happens, the refrigerator has to work harder and longer to keep a warm refrigerator compartment at the right temperature. The freezer might not have a problem since it works at a lower temperature and can adjust for small issues.
It’s important to clean the condenser coils regularly. This will help your refrigerator run well and keep the proper temperature in both the freezer and fridge compartments.
5. Faulty Thermistor
The thermistor is the part that senses the temperature inside the refrigerator. It sends this information to the control board. Then, the control board uses this data to control the cooling system and keep the set temperature.
If the thermistor is not working right, it can send wrong signals to the control board. This can cause problems, like a warm refrigerator while the freezer stays cold. The control board may not get the right signals to start or keep the cooling going for the fridge compartment.
To check if the thermistor is bad, you usually need to test its resistance with a multimeter. Appliance repair technicians can help identify a faulty thermistor. They can replace it, helping the refrigerator sense and keep the proper temperature again.
Steps to Diagnose and Fix a Warm Fridge with a Working Freezer
Before you call a professional for appliance repair, you can try some simple steps to find out why your refrigerator is warm but your freezer works. Often, cleaning the condenser coils or checking the airflow in the refrigerator can help solve the problem.
If the issue continues after you try these steps, you should get expert help. They can find and fix the real cause, which will help your appliance last longer and work better.
1. Checking the Evaporator Fan for Issues
- Listen for strange sounds: If you hear grinding, clicking, or humming from the freezer compartment, there may be an issue with the evaporator fan motor.
- Check the airflow: Open the freezer door and feel for cold air coming from the vent. If it’s weak or there is no airflow, the fan may be broken.
- Look for blockages: Turn off the refrigerator and unplug it. Find the evaporator fan, usually behind a panel in the freezer. Check for ice buildup or debris stopping the fan blades. If you see any, defrost the freezer and carefully remove the blockages.
If these steps do not fix the problem, you might need to replace the evaporator fan motor. It’s best to call a qualified appliance repair technician for help with this.
2. Clearing the Defrost Drain
- Find the drain: The defrost drain is usually at the back wall of the freezer compartment. It’s a tiny opening, often covered with a cap or grill.
- Clean the drain: Unplug the refrigerator. Then, gently pour warm water down the drain using a turkey baster or a small funnel. Do not use boiling water, as this can harm the drain parts.
- Remove any blockages: Use a pipe cleaner, a straightened coat hanger, or similar tool to clear away any ice or stuff blocking the drain.
Cleaning the defrost drain often can stop future blockages. This helps your refrigerator keep a proper temperature.
3. Testing the Damper Control Functionality
- Find the damper: You can usually find the damper control inside the refrigerator near the back wall, where the air comes from the freezer.
- Check the airflow: Open the refrigerator door and feel for cold air coming from the vent. Gently move the damper control back and forth to see if it opens and closes easily.
- Look for blockages: If the damper seems stuck or doesn’t move well, there may be a blockage. Carefully check the area for ice or debris that might be stopping the damper from moving.
If the damper control is broken or not working right, it’s best to call a professional appliance repair technician to fix or replace it.
Conclusion
So, “Why is my fridge warm but freezer is working?” If your fridge is warm but the freezer is working, it could be due to a faulty evaporator fan motor. Another common issue to check for is a clogged defrost drain. Cleaning the drain with warm water and removing any blockages can help regulate the temperature. Additionally, testing the damper control for any blockages or malfunctions is essential in maintaining proper airflow. If troubleshooting these issues doesn’t resolve the problem, it’s recommended to seek help from our qualified appliance repair technicians at Sub Zero Appliance Repair for further diagnosis and repair.
