LG Freezer Not Freezing but Fridge is Cold: Troubleshooting Tips

As an appliance engineer, one of the most common problems that I encounter is an LG freezer not freezing but the fridge is cold. A refrigerator is a vital appliance in any household, and it's important to resolve any issues as quickly as possible. LG is a leading brand in the appliance industry, and they manufacture high-quality refrigerators that provide exceptional performance. However, even the best appliances can experience issues from time to time. In this post, I will discuss the possible causes of an LG freezer not freezing but fridge is cold, and provide troubleshooting tips to help you resolve the issue.

Possible Causes of the Problem

There are several possible causes for an LG freezer not freezing but fridge is cold:

  • Defective Thermostat: The thermostat is responsible for regulating the temperature in the freezer. If it's defective, the freezer may not cool properly.
  • Damaged Defrost Timer: The defrost timer regulates the defrosting cycle of the freezer. If it's damaged, the freezer may not cool properly.
  • Malfunctioning Condenser Fan Motor: The condenser fan motor helps cool the compressor and condenser coils. If it's malfunctioning, the freezer may not cool properly.
  • Clogged Air Ducts: Air ducts circulate cold air from the freezer to the fridge. If they're clogged with ice or debris, the freezer may not cool properly.
  • Faulty Compressor: The compressor is responsible for compressing and circulating refrigerant throughout the system. If it's faulty, the freezer may not cool properly.
  • Low Refrigerant Levels: If the refrigerant levels are low, the freezer may not cool properly.
  • Faulty Door Seals: If the door seals are faulty, cold air may escape from the freezer, preventing it from cooling properly.

Tips on Troubleshooting the Problem

Here are some troubleshooting tips to help you identify and resolve the issue:

  • Check the Thermostat Settings: Make sure the thermostat is set to the correct temperature. If it's set too high, the freezer won't cool properly.
  • Inspect the Defrost Timer: Check the defrost timer to make sure it's functioning properly. If it's damaged or defective, it may need to be replaced.
  • Check the Condenser Fan Motor: Make sure the condenser fan motor is running properly. If it's malfunctioning or not running at all, it may need to be replaced.
  • Inspect the Air Ducts: Check the air ducts for any blockages or debris. If they're clogged, remove the blockage to allow cold air to circulate properly.
  • Check the Compressor: Check the compressor to make sure it's functioning properly. If it's faulty or not running at all, it may need to be replaced.
  • Inspect the Refrigerant Levels: If the refrigerant levels are low, it may indicate a leak in the system. Contact a professional to diagnose and repair the issue.
  • Inspect the Door Seals: Check the door seals to make sure they're sealing properly. If they're damaged or worn, they may need to be replaced.

Remember to unplug your refrigerator before attempting any repairs or troubleshooting.


If the troubleshooting tips don't resolve the issue, here are some alternatives:

  • Professional Appliance Repair Services: Contact a professional appliance repair service to diagnose and repair the issue. They have the expertise and tools necessary to fix the problem.
  • Purchasing New Parts for the Freezer: If the issue is with a specific part of the freezer, you may be able to purchase a replacement part and install it yourself.
  • Purchasing a New Freezer: If the freezer is old or has other underlying issues, it may be more cost-effective to purchase a new freezer rather than attempting repairs.

Remember to consider the age of your appliance and the cost of repairs versus the cost of a replacement when deciding on the best course of action.

My neighbor, Sarah, had been using her LG fridge-freezer for over five years with no issues. One day, she realized that her freezer was not freezing anymore but the fridge was still cold. Naturally, she was worried about her food being spoiled and was upset about the potential cost of repairs.

Sarah decided to check the simple things first and found that the thermostat settings were fine. She also cleaned out the frost buildup and removed any obstructions around the fan, but the problem persisted. She knew she needed professional help.

Sarah was hesitant to call an appliance repair service because she was worried about the cost. But, she came across some troubleshooting tips that suggested she perform further checks on the defrost timer and compressor.
