Freezer Gets Cold But Does Not Freeze

Introduction

It’s frustrating when your freezer feels cold to the touch but isn’t actually freezing your food solid. You open the door, expecting rock-hard ice cream, but find it’s soft and melty instead. This means your freezer isn’t doing its job and your food is at risk of spoiling. Common situations include recently adding lots of unfrozen food, a power outage, or simply noticing the problem gradually. Addressing this issue quickly is vital to prevent food waste and potential health hazards. Don’t delay let’s get your freezer freezing again!

Common Causes of Freezer Gets Cold But Does Not Freeze

Here are some common reasons why your freezer might be cold but not freezing:

Overloading the Freezer: Too much food at once, especially unfrozen items, raises the internal temperature.
Blocked Air Vents: Restricted airflow prevents the cold air from circulating properly.
Dirty Condenser Coils: Dust and debris on the coils reduce their ability to release heat, impacting cooling efficiency.
Faulty Door Seal: A damaged or dirty seal lets warm air in, making it harder to maintain freezing temperatures.
Incorrect Temperature Setting: The thermostat may be set too high (less cold).
Defrost System Issues: A malfunctioning defrost system can cause excessive frost buildup, insulating the cooling elements.
Failed Start Relay: If the start relay is bad, the compressor will not start correctly.
Compressor Problems: The compressor is the heart of the cooling system; if it’s failing, cooling is reduced.
Damaged Thermistor: The Thermistor is responsible for reporting the temperature and controlling the cooling process.

Symptoms Checklist

Check if you’re experiencing any of these symptoms:

Food is soft or partially frozen instead of solid.
Ice cream is melty.
Frost buildup inside the freezer is excessive.
The freezer runs constantly without properly freezing.
The freezer feels cold but not as cold as it should.
The motor seems to be running more than usual.
The sides of the freezer are unusually warm.

How to Fix Freezer Gets Cold But Does Not Freeze Step-by-Step Guide

Follow these steps to troubleshoot your freezer:

Unplug the Freezer: For safety, always unplug the freezer before starting any repairs.
Check the Temperature Setting: Ensure the thermostat is set to the coldest setting (usually marked with a snowflake or a number like 7 or 9). Wait 24 hours to see if the temperature drops.
Clear Air Vents: Make sure no food items are blocking the air vents inside the freezer. Rearrange items if necessary.
Defrost the Freezer: If there’s excessive frost buildup, manually defrost the freezer. Unplug it and leave the door open until all the frost melts. Use towels to absorb the water.
Clean the Condenser Coils: Locate the condenser coils (usually on the back or bottom of the freezer). Use a vacuum cleaner with a brush attachment to gently remove dust and debris.
Inspect the Door Seal: Examine the rubber gasket around the freezer door for cracks, tears, or dirt. Clean the seal with warm soapy water and a cloth. If it’s damaged, it may need replacing later (but try cleaning first).
Check for Overloading: Remove some items if the freezer is packed too tightly. Allow space for air to circulate.
Check for Proper Ventilation: Ensure the freezer has adequate space around it (at least a few inches) for proper ventilation.
Listen to the Compressor: After plugging the freezer back in, listen to the compressor (usually a black, round or oval motor on the back). It should start running. If it’s making unusual noises (clicking, buzzing, or not running at all), it could indicate a problem.
Allow Time to Stabilize: After making any adjustments, give the freezer at least 24 hours to stabilize and reach the correct temperature.
Monitor the Temperature: Use a thermometer to check the freezer’s temperature after 24 hours. It should be around 0F (-18C).
Reseat the start relay. The start relay can often be found next to the compressor. With the unit unplugged, gently tap the start relay in order to reseat it. Ensure it is making a good connection.

Fix the Issue Without Buying Parts

Here are some things you can try without immediately buying new parts:

Reset: Unplug the freezer for 30 minutes to reset the system. Plug it back in and see if it starts cooling properly.
Cleaning: Regularly clean the condenser coils and door seal to maintain efficiency.
Recalibration: Some freezers have a calibration setting. Check your user manual to see if you can recalibrate the temperature.
Inspection Tips: Regularly inspect the inside of the freezer for ice buildup. Scrape if neccessary, but avoid sharp objects.
Maintenance Basics: Avoid overcrowding the freezer and keep the door closed as much as possible. This will also prevent condensation.

When Replacement Might Be Necessary

If the problem persists after trying all the troubleshooting steps, a faulty compressor, start relay, or thermistor may be the culprit. Having these professionally replaced can be costly, often ranging from $200 to $600, depending on the part and labor costs. If the freezer is old or the repairs are extensive, it might be more cost-effective to replace the entire unit. Common parts that fail include the compressor, thermostat, and door seal.

Safety Warning

Always unplug the freezer before performing any repairs.
Avoid working on electrical components if you’re not comfortable doing so.
Be careful when handling sharp objects or tools.
Avoid working near wet floors to prevent electric shock.
If unsure, consult a qualified technician.

FAQ

Here are some frequently asked questions:

Q: How long should it take for my freezer to freeze food after I plug it in?A: It usually takes 2-4 hours, but can take up to 24 hours to reach the correct temperature.
Q: Why is there frost buildup inside my freezer?A: Excessive frost buildup can be caused by a faulty door seal, frequent opening of the door, or a malfunctioning defrost system.
Q: What temperature should my freezer be set to?A: The ideal freezer temperature is 0F (-18C).
Q: How often should I clean the condenser coils?A: It’s recommended to clean the condenser coils every 6 months to a year.
Q: Can I use a hair dryer to defrost my freezer?A: It is not recommended as it’s a safety hazard. Just leave the door open and be patient.

Conclusion

Troubleshooting a freezer that gets cold but doesn’t freeze can seem daunting, but by following these steps, you can often diagnose and fix the problem yourself. Remember to prioritize safety and take your time. By trying these simple solutions, you can potentially save money on repair costs and prevent food spoilage. If you’ve tried everything and your freezer still isn’t freezing, it might be time to call a qualified technician. Good luck!
