LG Freezer Not Freezing — Surrounding East Rand Areas Repair
An LG freezer in Surrounding East Rand Areas that's "not freezing" is a common callout across Ekurhuleni. An LG freezer that can't hold -18°C usually points to a defrost failure (the evaporator ices and insulates itself), a weak compressor, a refrigerant undercharge, or a door-seal breach letting warm moist air in. Softening ice cream is often the first sign, followed by visible frost buildup at the top of the cabinet.
Technical Overview — LG freezer
LG chest and upright freezers run a hermetic compressor with a single evaporator and a mechanical or electronic defrost cycle. Because they hold sub-zero temperatures, a small refrigerant loss or a failed defrost heater shows up fast as softening stock.
- Hermetic compressor (single-speed or inverter)
- Single evaporator coil
- Defrost heater + bimetal thermostat
- Condenser fan + evaporator fan
- Door seal critical for -18°C hold
Not Freezing — Common Causes & Checklist
An LG freezer that can't hold -18°C usually points to a defrost failure (the evaporator ices and insulates itself), a weak compressor, a refrigerant undercharge, or a door-seal breach letting warm moist air in. Softening ice cream is often the first sign, followed by visible frost buildup at the top of the cabinet.
Common Causes
- 01Defrost heater or defrost thermostat open — evaporator ices solid
- 02Compressor losing capacity or cycling off on the overload
- 03Refrigerant undercharge from a slow leak
- 04Door seal torn or gasket not seating — warm air ingress and heavy frost
- 05Condenser coil blocked or condenser fan failed — can't reject heat
Diagnostic Checklist
- Check the cabinet temperature with a probe (target -18°C)
- Inspect for heavy frost on the evaporator and at the door opening
- Test defrost heater, bimetal and defrost sensor
- Verify the door gasket seals fully around the frame
- Clean the condenser coil and confirm the condenser fan runs
- Pressure-test the sealed system if charge is low

Frequently Asked Questions
Why is my LG freezer frosting up but not freezing?
That pattern almost always means a defrost failure — the evaporator ices over, insulates itself, and stops absorbing heat. The fix is usually the defrost heater or sensor, not the compressor.
