LG Fridge Not Cooling in Morningside
A warm fridge with a frozen freezer is one of the most common LG refrigerator faults we attend in Morningside. The cause is rarely the gas charge — it is almost always a failed defrost cycle, a faulty thermistor, a weak compressor or an inverter board that has stopped driving the compressor. Reyds isolates the exact failure on site so you only pay to replace the part that has actually failed.

Common Symptoms in Morningside
- Fresh food compartment above 7°C
- Freezer still freezing but fridge warm
- Ice build-up on the back wall of the fridge
- Compressor hot to the touch but not running
- Error code Er FF, Er CO or Er 1F on the display
What Causes This Fault
- Defrost heater, fuse or bi-metal open circuit
- Evaporator fan motor stalled
- Thermistor reading out of tolerance
- Inverter board not outputting to the compressor
- Compressor mechanical failure (valve or winding)
Our Repair Process
- 01Measure fridge and freezer compartment temperatures
- 02Read fault codes from the LG control board
- 03Test defrost heater, bi-metal and defrost timer resistance
- 04Check thermistor resistance against the LG temperature chart
- 05Verify inverter output voltage to the compressor
- 06Replace the confirmed failed component and verify recovery
When to Call a Technician
Book a technician the moment the fridge compartment climbs above 5°C — a defrost fault left for days will freeze the evaporator solid and can damage the compressor.
Frequently Asked Questions
Why is my freezer cold but the fridge warm?
The most common cause in Morningside homes is a defrost system failure — ice blocks the evaporator coil, so cold air can't reach the fridge compartment. A blocked or failed evaporator fan produces the same symptom.
Could it just need a gas recharge?
Rarely. LG fridges are sealed systems; low gas means a leak. We pressure-test before adding refrigerant and will not recharge a leaking system without repairing the leak first.
Is it worth repairing or should I replace the fridge?
Most LG not-cooling faults (defrost, fan, thermistor, inverter) are economical to repair. A confirmed compressor failure on an older unit is the one case we'll discuss replacement with you honestly.
