Freezer Not Cooling as It Should? Causes & Solutions
Why This Matters
A freezer that doesn’t cool properly isn’t just annoying — it can lead to:
- Spoiled food
- Higher electricity bills
- Unnecessary stress
The good news? Many issues are easy to fix. Let’s break down the causes and solutions.
Common Reasons Why a Freezer Isn’t Cooling
1. Thermostat Set Incorrectly
Sometimes the temperature control is accidentally adjusted. If it’s set too high, the freezer won’t get cold enough.
🎥 Refrigerator not Cooling? Check these things first! shows how to check and reset your thermostat settings to restore proper cooling.
2. Faulty Thermostat
If the thermostat is damaged or misreading, it won’t signal the cooling system to run.

3. Dirty Condenser Coils
Coils at the back or bottom release heat. If covered in dust, heat can’t escape, and cooling weakens.
🎥 Freezer Not Cooling HOW THEY WORK and REPAIR walks through how condenser coils affect cooling and how to clean them safely.
4. Compressor Problems
The compressor is the “engine” of your freezer. If it’s failing or not running, the freezer won’t stay cold.

5. Condenser Fan Not Working
The fan near the compressor keeps refrigerant cool. If it’s broken, the freezer overheats and cooling drops.

6. Damaged or Weak Door Seals
If the door seal is cracked, dirty, or loose, cold air escapes and warm air enters.

7. Evaporator Fan Malfunction
This fan circulates cold air inside the freezer. If it fails, parts of the freezer may feel warm even if the compressor runs.

8. Blocked Airflow Inside
Overloading the freezer or covering vents can stop circulation and reduce cooling.

Safe Solutions You Can Try
✅ Check and reset the thermostat Set to freezing level: –18°C to –20°C
✅ Inspect the door seal Close the door on a piece of paper. If it slips out easily, replace the gasket.
✅ Avoid overloading Don’t block vents. Arrange items for airflow.
✅ Clean condenser coils Unplug the freezer. Use a soft brush or vacuum. Clean twice a year.
✅ Defrost if there’s ice buildup Excess frost blocks airflow. Switch off, defrost fully, then restart.
When to Call a Technician
Some problems require professional help:
- Compressor failure
- Faulty thermostat control board
- Evaporator or condenser fan replacement
- Refrigerant (gas) leak
⚠️ Do not attempt to repair compressors or handle refrigerant yourself.
💡 Pro Tips to Prevent Cooling Problems
- Use a voltage stabilizer to protect against current fluctuations
- Avoid frequent door openings
- Defrost regularly (unless frost-free)
- Clean inside and outside surfaces
- Follow your user manual’s maintenance instructions
Final Note
A freezer that isn’t cooling properly isn’t safe for food storage. Start with simple checks like thermostat settings, cleaning coils, and inspecting door seals. If the issue persists, contact a qualified technician.
👉 If your freezer is old or inefficient, replacing it with a modern, energy-saving model may be more cost-effective than repeated repairs.
