What You’re Experiencing
Your freezer is not maintaining 0 degrees Fahrenheit. Ice cream is soft, frozen food is thawing, and ice is melting. The compressor may or may not be running. This is a food safety emergency — thawed food that refreezes can harbor dangerous bacteria. In Atlanta, freezer failures during the hot summer months are especially costly, as ambient temperatures in garages and utility rooms can exceed 90 degrees, making the unit work even harder and food spoil faster.
Common Causes
1. Dirty Condenser Coils
Same as a refrigerator — dirty coils reduce the system’s ability to remove heat. Pet hair, dust, and kitchen grease accumulate on the coils and act as insulation, forcing the compressor to run longer and less effectively. DIY fix: free.
2. Evaporator Coil Frost Buildup
If the defrost system fails, frost accumulates on the evaporator coils and blocks airflow. You may see heavy ice on the back wall or hear the fan struggling. Typical repair cost: 50–50.
3. Defective Start Relay or Compressor
The start relay helps the compressor motor start. When it fails, the compressor clicks on and off without running. A failed compressor itself produces the same clicking pattern. Start relay: 00–00. Compressor: 00–00.
4. Faulty Thermostat
The thermostat controls when the compressor cycles on and off. If stuck in the off position, the compressor never runs. Typical repair cost: 00–00.
5. Door Seal Failure
A damaged gasket lets warm air in, causing the compressor to overwork and ice to build up unevenly. Atlanta’s humidity makes this worse — warm, moist air entering the freezer creates frost rapidly. Typical repair cost: 0–50.
Brand-Specific Issues
Samsung Freezers
Samsung French door refrigerators have a well-documented issue where the evaporator coils in the freezer compartment ice over due to a defrost drain that freezes shut. Samsung released a service bulletin and a repair kit that includes a new drain assembly and heating element. If your Samsung freezer frosts over repeatedly, ask your technician about this specific fix rather than simply defrosting it each time.
LG Freezers
LG refrigerators with the Linear Compressor have faced reliability concerns. If your LG freezer is not maintaining temperature and the compressor makes an intermittent knocking sound, the compressor may be failing. LG extended the compressor warranty to 10 years on many models, so check your warranty status before paying for a compressor replacement out of pocket.
Whirlpool Freezers
Whirlpool standalone freezers and the freezer compartments in Whirlpool refrigerators commonly develop defrost timer failures. The defrost timer controls how often the unit enters the defrost cycle. When it sticks in the cooling position, frost builds up until airflow stops. This is a straightforward repair that most Atlanta technicians can complete in under an hour.
DIY Checks Before Calling a Pro
Check 1: Verify the Temperature Setting
Ensure the freezer is set to 0 degrees Fahrenheit. After a power outage, the setting may have changed. Atlanta experiences frequent power fluctuations during summer storms, so check this first.
Check 2: Clean the Condenser Coils
Unplug the unit. Vacuum the coils on the back or underneath with a brush attachment. Plug back in and give it 24 hours to stabilize.
Check 3: Check the Door Seal
Close the door on a dollar bill. If it pulls out easily, the seal needs replacing.
Check 4: Do Not Overfill or Underfill
A freezer that is too full blocks airflow between items. A freezer that is too empty does not retain cold efficiently. Aim for about 75 percent full for optimal performance.
Check 5: Listen for the Compressor
Put your ear near the bottom-back of the unit. You should hear a low humming. Clicking on and off means a start relay issue. Silence may indicate a compressor failure.
Safety Precautions
Freezer repairs involve refrigerant and electrical components that require careful handling:
- Never attempt to recharge refrigerant yourself. Refrigerant handling requires EPA Section 608 certification. Releasing refrigerant into the atmosphere is illegal and the chemicals are harmful to breathe.
- Unplug before cleaning coils or inspecting components. Even though freezers run on standard 120-volt outlets, the compressor and start relay carry enough current to cause injury.
- Address thawed food safety promptly. According to the USDA, frozen food that has thawed and been above 40 degrees Fahrenheit for more than two hours should be discarded. Do not refreeze meat, seafood, or dairy that has fully thawed.
- Be cautious with chest freezers. When leaning into a deep chest freezer for inspection, ensure the lid is propped securely to prevent it from closing on you. Some older models do not have safety releases.
When to Call a Professional
- Temperature will not reach 0 degrees Fahrenheit after 24 hours with clean coils
- Compressor clicks but will not run
- Heavy frost on evaporator coils
- Food is thawing despite correct settings
- Chest freezer will not power on at all
Questions to Ask Your Technician
- Is the compressor still under manufacturer warranty? Many compressors carry 5 to 10 year warranties even after the general warranty expires. This can save hundreds on the most expensive repair.
- Is the defrost system the root cause of the frost buildup? Simply defrosting the coils without fixing the defrost heater, timer, or thermostat means the problem will return within weeks.
- Should I repair or replace the unit? If the compressor has failed on a freezer more than 8 years old, replacement is often more cost-effective than a 00 to 00 compressor repair.
- Is my freezer location contributing to the problem? Freezers in unconditioned Atlanta garages work much harder in summer heat. Your technician can advise whether the location is suitable.
- What maintenance should I do to prevent this from happening again? Most technicians recommend cleaning condenser coils every six months and checking door seals annually.

Typical Repair Timeline
Freezer repairs vary depending on the component involved:
- Scheduling: Same-day or emergency service is typically available for freezer failures across metro Atlanta, given the food spoilage risk.
- Diagnosis: 15–30 minutes to test the compressor, thermostat, and defrost system.
- Start relay or thermostat: 20–40 minutes with parts on hand.
- Defrost system repair: 45 minutes to 1.5 hours, depending on ice accumulation and component access.
- Compressor replacement: 2–4 hours. Parts are often available next-day for common models.
