This guide can be used for all major LG refrigerator/freezer models, including the following specific ones: LFX31945ST LMX25984SW LMX25986ST LMX28988SB LMX28988ST LMX28988SW LRDC22743ST LRDC22744ST LRSC26980SB LSFS213ST LFX21976ST LFX25950SB LFX25950SW LFX25950TT LFX25976ST LFX25991ST LFX28978SB LFX28978SW LFX28979ST LFX31925ST LFX31935ST Step 1 – Clean the condenser coilsThe easiest thing you can do to get your LG freezer working properly again is to clean the condenser coils. The condenser coils dissipate heat when refrigerant goes through them, which helps to keep your freezer cool. When they become covered in dust or frost, it can prevent your freezer from working properly. You can clean the condenser coils easily by following these steps:
Step 2 – Test the temperature control thermostatThe purpose of the temperature control thermostat is to measure the temperature in your freezer and then tell the main control board this information so it can direct other components to turn on and off in your freezer. When it stops working, your LG freezer won’t get cold enough. This is how you can test the temperature control thermostat:
Step 3 – Test the condenser fanThe next step is to check the condenser fan in your LG freezer. This fan helps to cool down the condenser coils. If it becomes faulty, your freezer might not cool down to the right temperature. This is how you can test the condenser fan:
Step 4 – Test the start relayThe start relay works in conjunction with the start winding to ensure the compressor can function. When the start relay stops working, your LG freezer won’t get cold enough. This is how you can test the start relay:
Step 5 – Test the compressorThe compressor is responsible for compressing the refrigerant and for distributing it through the condenser coils to keep your fridge and freezer cold enough. If the compressor doesn’t function correctly, your LG freezer won’t stay cool enough. This is how you can test the compressor:
Step 6 – Replace the main control boardThe final step (and your final option) is to replace the main control board. This can be risky, as it isn’t guaranteed to solve the problem. Alternatively, you may decide to purchase a new freezer instead. Why is freezer not working but fridge is?Loose Door Seals
If your freezer isn't as cold as it should be, but your refrigerator is working fine, you may want to take a look at the freezer's door seals, or gaskets. Due to normal wear and tear, these door gaskets can dry out and start to crack.
What to do when LG freezer is not freezing?The easiest thing you can do to get your LG freezer working properly again is to clean the condenser coils. The condenser coils dissipate heat when refrigerant goes through them, which helps to keep your freezer cool.
Why is my refrigerator not cooling or freezing?There are several causes for a refrigerator that doesn't cool, including dirty condenser coils, poor ventilation, improper installation, faulty or dirty gasket seals, unorganized food storage, appliance location and malfunctioning internal parts.
