Freezer Not Freezing in Colchester
Is your freezer not freezing properly?
If your freezer is no longer keeping food frozen — or is taking too long to freeze — it usually means the appliance is not reaching or maintaining the correct temperature.
East Coast Appliances helps customers across Colchester, Chelmsford, and Ipswich diagnose and repair freezer faults.
What causes this problem?
- Damaged or worn door seal letting warm air in continuously
- Frost build-up blocking the evaporator coils and restricting airflow
- Faulty thermostat not triggering the compressor to cool
- Overfilled freezer preventing proper cold air circulation
- Condenser coils at the back dirty or dusty, reducing heat exchange efficiency
- Compressor fault — the compressor is the main cooling component and is critical to freezer operation
- Refrigerant leak causing a gradual loss of cooling capacity
- Faulty defrost system allowing excessive frost to accumulate
Common symptoms
- Food is soft, partially thawed, or not frozen solid
- Freezer feels warmer than usual to the touch
- Excessive frost or ice build-up on the walls or shelves
- Compressor running continuously but freezer not reaching temperature
- Freezer section cold but fridge section of a fridge freezer running warm
- Unusual sounds — clicking, buzzing, or humming — from the compressor area
- Items stored near the door defrosting while items at the back remain frozen
Can you fix it yourself?
- Check the door seal for damage, gaps, or food debris preventing a proper close — a worn seal is one of the most common causes
- Make sure the freezer is not overfilled — air needs to circulate around the food to freeze effectively
- Check the thermostat setting has not been accidentally changed
- Defrost the freezer manually if there is a significant frost build-up on the walls — this can sometimes restore performance temporarily
- Clean the condenser coils at the back of the appliance using a vacuum or soft brush if they are heavily clogged with dust
- Ensure there is adequate space around the appliance for ventilation — freezers need airflow around the condenser coils to work efficiently
If these checks do not restore correct freezing, a professional repair is required to diagnose the compressor, thermostat, refrigerant charge, or defrost system.
When to call a professional
If your freezer is not reaching temperature after basic checks, the fault is likely internal. Thermostat, compressor, and refrigerant faults cannot be safely diagnosed or repaired without specialist equipment.
Continued use of a freezer that is not freezing properly risks food spoilage and, in some cases, can worsen the underlying fault.

Frequently Asked Questions
Why is my freezer not freezing but the fridge is still cold?
In a fridge freezer, this often points to a fault with the freezer thermostat, a blocked evaporator, or a defrost system fault — all of which affect the freezer compartment first while the fridge stays cool for longer.
Will defrosting my freezer fix the problem?
If the cause is excessive frost build-up blocking the evaporator, a full manual defrost can restore performance temporarily. However, if the freezer repeatedly ices up and loses cooling, the underlying cause — usually a faulty defrost heater or sensor — still needs to be repaired.
What temperature should a freezer be?
A freezer should maintain a temperature of -18°C or below to keep food safely frozen. Most freezers allow you to set the temperature between -15°C and -22°C. If your freezer is reading warmer than -15°C, it is not performing correctly.
