Common Causes of Freezer not freezing on LG LFXS32766S fridge

The most common causes of a freezer not freezing in LG LFXS32766S fridge are:

  • Thermostat malfunctions
  • Evaporator fan problems
  • Dirty/ faulty condenser coils
  • Faulty compressor motor
  • Low refrigerant level
  • Door seal issues causing warm air to enter freezer
  • Blocked air vents

Another possible cause of a freezer not freezing in LG LFXS32766S fridge is a malfunctioning defrost system. If the defrost system fails, ice can build up on the evaporator coils, preventing the freezer from cooling properly. This can be caused by a faulty defrost thermostat, defrost timer, or defrost heater.

In addition, if the freezer is overfilled with food, it can restrict air flow and prevent proper cooling. It is important to ensure that there is enough space between items in the freezer to allow for proper air circulation.

How to diagnose Refrigerator and Freezer Problems

Diagnosing freezer problems in your LG LFXS32766S fridge requires proper troubleshooting skills. The first step is to unplug the fridge and then review the manual to find basic diagnostic instructions. In addition, here are some more tips:

  • Check whether the fridge is unplugged and the power cord plugged in properly.
  • Make sure there are no obstructions around the fridge’s back and sides.
  • Ensure the temperature in the freezer is set correctly.
  • Ensure that the door is not left open for too long.

If the above tips do not solve the problem, you may need to check the condenser coils. Dirty coils can cause the fridge to overheat and malfunction. You can clean the coils using a vacuum cleaner or a coil brush.

Another common issue with refrigerators is a faulty thermostat. If the temperature in the fridge is not consistent, it may be due to a faulty thermostat. You can test the thermostat using a multimeter or by observing the temperature readings over a period of time.

How to Check the Thermostat in Your LG LFXS32766S Fridge

The thermostat is an important component of your LG LFXS32766S fridge that controls the temperature inside your freezer. If it malfunctions, your freezer may not freeze properly. To check your thermostat:

  • Check the temperature inside your freezer and compare it to the thermostat setting.
  • If the temperature in the freezer is above the thermostat setting, you may need to adjust the thermostat settings.
  • If the thermostat is faulty, it needs to be replaced by an experienced technician.

It is important to note that a faulty thermostat can also cause your fridge to run constantly, leading to higher energy bills and potential damage to the compressor. If you notice that your fridge is running more than usual, it may be worth checking the thermostat as part of your troubleshooting process.

Checking the Evaporator Fan on an LG LFXS32766S Fridge

The evaporator fan is responsible for circulating the cold air generated by the evaporator coils throughout the freezer compartment to maintain a consistent temperature. If it’s not functioning correctly, it can cause your freezer to not freeze. To check for evaporator fan problems:

  • Turn off the power to the fridge and unplug it.
  • Remove the freezer shelves and the back panel of the freezer compartment.
  • Check if the fan is free of debris and if it rotates when power is on.
  • If the fan is dirty, clean it carefully and replace it if it’s faulty.

It’s important to note that a faulty evaporator fan can also cause your fridge to not cool properly. This is because the fan is responsible for circulating the cold air from the freezer compartment to the fridge compartment. If you notice that your fridge is not as cold as it should be, it’s worth checking the evaporator fan to see if it’s functioning correctly.

How to Check the Condenser Coils on your LG LFXS32766S Fridge

The condenser coils are responsible for dissipating heat from the fridge. If they are clogged or dirty, they can cause the freezer to not freeze properly. To clean the condenser coils:

  • Unplug the fridge and remove the back panel of the fridge.
  • Use a brush or vacuum cleaner to remove the debris from the coils.
  • If the coils are severely clogged, use coil cleaner or contact a technician for assistance.

It is recommended to check the condenser coils at least twice a year to ensure they are clean and functioning properly. Neglecting to clean the coils can lead to increased energy consumption and potential damage to the fridge’s compressor. Additionally, if you notice any strange noises or a decrease in cooling performance, it may be a sign that the condenser coils need to be cleaned or serviced.

Troubleshooting the Compressor Motor of your LG LFXS32766S Fridge

If your compressor motor isn’t functioning, it can cause a freezer not to freeze. Here are the steps to troubleshoot:

  • Unplug the fridge and locate the compressor motor.
  • Check for any visible damage like damage to wires or burnt-out contacts.
  • If there is any visible damage, replace the motor or contact a professional for assistance.

However, if there is no visible damage, you can use a multimeter to test the motor’s continuity. Set the multimeter to the ohms setting and touch one probe to each of the motor’s terminals. If the multimeter reads zero ohms, the motor has continuity and is functioning properly. If the multimeter reads infinite ohms, the motor has no continuity and needs to be replaced.

Tips for Fixing a Leaking Refrigerator or Freezer

If you find water accumulating in or around the base of the fridge, it may be due to a water leak. Here are some tips for fixing a leaking refrigerator or freezer:

  • Check the defrost drain located at the back of the freezer and remove any debris.
  • Ensure there is no water filter blockage.
  • Fix any damaged water supply lines to the refrigerator.

Another common cause of a leaking refrigerator or freezer is a clogged or frozen water line. To fix this issue, turn off the water supply to the fridge and use a hairdryer to thaw the frozen line. You can also try using a turkey baster to flush out any debris that may be causing the clog. Once the line is clear, turn the water supply back on and check for any leaks.
