4. Install the new gasket by pushing it into place.
5. Reattach the gasket back into the gasket retainer.
6. Put back the door trim.

3. Malfunctioning Start Relay

The start relay is responsible for initiating the freezing process in your LG freezer.

If the start relay is not functioning correctly, it can prevent the compressor from running, leading to a freezer that doesn’t freeze properly.

How to Fix a Malfunctioning Start Relay

To determine if the start relay is the issue and resolve it, follow these steps:

1. Use a multimeter tester to test the start relay’s continuity between its start and run terminals.
2. If there is no continuity, it indicates that the start relay is not working and needs to be replaced.
3. Replace the start relay with a new one that matches the specifications of the original relay.

4. Malfunctioning Evaporator Fan Motor

The evaporator fan motor plays a crucial role in circulating cold air throughout the freezer.

If this fan motor is malfunctioning, it can result in inadequate airflow, causing the freezer not to reach its full freezing capacity.

How to Fix a Malfunctioning Evaporator Fan Motor

To determine if the evaporator fan motor is the issue and resolve it, follow these steps:

1. Check the condition of the fan motor.
2. Use a multimeter to test the continuity of the motor. If there is no continuity, it indicates a faulty motor that needs replacement.
3. Spin the motor blades manually. If they do not spin freely, it indicates a defective motor that should be replaced.

5. Problem with the Defrost System

One of the most common causes of freezer problems is a malfunctioning defrost system.

The defrost system includes a heater that melts the frost accumulated on the evaporator coils. If this system malfunctions, it can significantly impact the freezer’s freezing capacity.

How to Fix a Problem with the Defrost System

To fix a problem with the defrost system, follow these steps:

1. Check the defrost system for any signs of malfunction.
2. If the defrost system is faulty, it is recommended to seek professional assistance to properly diagnose and repair the issue.

6. Freezer Not Working After a Power Outage

Sometimes, a power outage can cause issues with the freezer, leading to inadequate freezing.

If you notice that your LG freezer is not working properly after a power outage, there are a few steps you can take to troubleshoot the problem.

How to Fix a Freezer That’s Not Working After a Power Outage

To fix a freezer that’s not working after a power outage, follow these steps:

1. Check the wall socket or electrical outlet where the freezer is connected to ensure it is still functioning and supplying the required voltage.
2. Inspect the power cord for any damage caused by power surges during the outage. If the power cord is damaged, replace it.
3. If everything appears to be in order, unplug the freezer or turn off the circuit breaker that it is connected to for about 30 seconds. Then, turn the circuit breaker back on and plug the freezer back in. This can help reset the freezer and restore normal operation.

7. Bad Condenser Fan Motor 

The condenser fan motor is responsible for pulling outside air to cool the condenser coils and keep the compressor cool.

If the condenser fan motor is not functioning correctly, it can cause the compressor to overheat and result in a freezer that doesn’t cool down properly.

How to Fix a Bad Condenser Fan Motor

To determine if the condenser fan motor is the issue and resolve it, follow these steps:

1. Check the condenser fan motor to see if it is working.
2. Attempt to manually turn the fan blades. If they do not turn freely, it indicates a faulty motor that needs replacement.
3. Use a multimeter to test the motor’s continuity. If there is no continuity, it confirms a defective motor that should be replaced.

8. Bad Temperature Control Thermostat

The temperature control thermostat is responsible for sending voltage to the compressor and fan motors, enabling them to run.

If the thermostat is faulty and unable to deliver the required voltage, it can result in a freezer not freezing properly, while the fridge remains cold.

How to Fix a Bad Temperature Control Thermostat

To determine if the temperature control thermostat is the issue and resolve it, follow these steps:

1. Turn the thermostat from its lowest to highest temperature setting and listen for a click. If you don’t hear a click, it indicates a faulty thermostat.
2. Use a multimeter to test the thermostat for continuity. If there is no continuity at any temperature setting, it confirms a defective thermostat that needs to be replaced.

9. Bad Compressor

The compressor is a vital component of the cooling system responsible for compressing the refrigerant and circulating it through the evaporator and condenser coils.

If all other components have been checked and the freezer is still not freezing properly, the compressor may be the culprit.

How to Fix a Bad Compressor

Fixing a bad compressor is a complex task best left to a qualified HVAC technician.

However, before replacing the compressor, perform the following steps:

1. Ensure that all other components of the cooling system are functioning correctly.
2. Use a multimeter to check the compressor’s continuity between its electrical pins. If there is an open circuit, it indicates a defective compressor.
3. Consult an HVAC technician to assess the compressor’s repairability. If it cannot be repaired, it will need to be replaced.

10. Bad Thermistor

The thermistor, also known as the temperature control sensor, reads the air temperature and sends the information to the control board.

It works in conjunction with the temperature control thermostat.

A malfunctioning thermistor can provide incorrect readings, resulting in the control board failing to provide the necessary power to the motor and compressor.

How to Fix a Bad Thermistor

To determine if the thermistor is the issue and resolve it, follow these steps:

1. Use a multimeter to test the thermistor’s continuity. If the readings do not vary with changes in the freezer’s temperature, it confirms a defective thermistor.
2. Replace the thermistor with a new one to ensure accurate temperature readings and proper operation of the control board.
