Most common repairs needed to fix a LG freezer

Compressor Start Relay Replacement

The compressor start relay helps the compressor kick on and run, which is essential for cooling the freezer. If the start relay is malfunctioning, the compressor may fail to start or run intermittently, leading to inadequate cooling and a rise in freezer temperature. You might notice that food isn't freezing properly or that the freezer compartment feels warm. To address this issue, inspect the compressor start relay for any signs of damage or wear. If you suspect the start relay is at fault, schedule an in-home repair appointment through Sears Home Services to have a technician diagnose and replace the faulty relay.

Temperature Control Thermostat Replacement

A common sign of a bad temperature control thermostat is temperature inconsistency within the freezer, leading to either insufficient cooling or excessively cold conditions. You might notice fluctuations in temperature and find items thawing. The freezer may run continuously or cycle frequently, indicating a failure to maintain the set temperature. In some cases, the thermostat might cause the freezer to be entirely non-responsive, leading to a complete lack of cooling.

PCB Replacement

When your freezer is not freezing, a malfunctioning electronic control board could be causing the problem. The electronic control board receives signals from various sensors to monitor the temperature inside the freezer. Using the information it receives from these sensors, the board starts or stops the compressor, fans, defrost cycle and other components. A bad internal relay or corrupted internal logic on the circuit board can prevent the electronic control board from sending electric current to the compressor for cooling. When your freezer isn't freezing, schedule service through Sears Home Services. Our technician will visit your home and fix the cooling problem in your freezer.

What to expect when you experience an LG freezer not freezing issue

How is the freezer not freezing issue fixed?

Correcting most freezer not freezing issues involves replacing the compressor start relay, temperature control thermostat, or PCB. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.

Sears Home Services recommendations for a freezer not freezing problem

When a freezer is not freezing, it can be for many reasons. To avoid replacing unneeded parts, we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of freezer failures.

What to look out for with a freezer not freezing diagnosis

Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your freezer problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.

Frequently Asked Questions

Why won’t my LG freezer get cold enough to freeze items?
A failing evaporator fan, defrost system malfunction, or low refrigerant can hinder freezing. Check for ice buildup around the evaporator blocking air circulation.
How do I confirm the defrost system is working?
Look for excessive frost on the coils. If present, the defrost heater, thermostat, or control board might be failing. Unplugging the freezer and testing with a multimeter can pinpoint the faulty part.
Could a sealed system leak reduce freezing power?
Yes. If refrigerant escapes, the compressor can’t reach the necessary low temps. A certified technician must repair leaks and recharge the system.
When should I call a technician for an LG freezer that won’t freeze?
If defrost checks or cleaning coils don’t improve cooling, the compressor, sealed system, or control board may be at fault. A professional can perform advanced diagnostics.
