Title: Frigidaire Freezer LFFH20F3QWC Coils Frozen: A Troubleshooting Guide

Hey there! Are you facing a chilly predicament with your Frigidaire Freezer LFFH20F3QWC? Well, fret not, because we’re here to help you thaw out the issue! One common problem with this freezer model is frozen coils, which can cause your freezer to lose its cool. In this blog post, we’ll delve into the causes of frozen coils and provide you with a step-by-step troubleshooting guide to get your freezer back up and running smoothly. So, let’s jump right in and get to the bottom of this frosty situation!

Understanding the Freezer Coils

Before we dive into the troubleshooting process, let’s take a moment to understand the freezer coils and their role in keeping your freezer functioning optimally. The coils in your Frigidaire Freezer LFFH20F3QWC are responsible for cooling the air inside the freezer. They work by extracting heat from the air, which causes moisture to condense and freeze on the coils. Over time, this frost buildup can become excessive and lead to various issues, including frozen coils.

Causes of Frozen Coils

Now that we know the basics, let’s explore the possible causes of frozen coils in your Frigidaire Freezer LFFH20F3QWC. By identifying the root cause, you’ll be better equipped to troubleshoot and resolve the issue. Here are a few common culprits:

1. Poor Air Circulation: If the airflow inside your freezer is restricted, it can lead to inadequate heat exchange and excessive frost buildup on the coils. This can be caused by items blocking the vents or improper arrangement of food items.

2. Defective Defrost Timer: The defrost timer controls the defrost cycle of your freezer. If it malfunctions or gets stuck in the cooling mode, the coils may not receive the necessary defrosting, resulting in frozen coils.

3. Faulty Defrost Heater: The defrost heater is responsible for melting the frost on the coils during the defrost cycle. If it fails to function properly, the coils may remain frozen.

4. Damaged Door Gasket: A worn-out or damaged door gasket can allow warm air from outside to enter the freezer, causing excessive frost buildup on the coils.

5. Temperature Setting: If the temperature setting on your freezer is too low, it can cause the coils to freeze. Ensure that the temperature is set at the recommended level for optimal performance.

Troubleshooting Frozen Coils

Now that we have a good understanding of the possible causes, let’s move on to troubleshooting the frozen coils in your Frigidaire Freezer LFFH20F3QWC. Follow these steps to get your freezer back in tip-top shape:

Step 1: Unplug the Freezer

To ensure your safety, start by unplugging the freezer from the power source. This will prevent any electrical mishaps while you work on troubleshooting the issue.

Step 2: Remove Contents and Defrost

Next, remove all the contents from the freezer and place them in a cooler or another freezer if available. This will give you ample space to work with and prevent any damage to your food items. Allow the freezer to defrost naturally, or you can speed up the process by placing bowls of hot water inside and keeping the freezer door open.

Step 3: Inspect the Air Vents and Door Gasket

While the freezer is defrosting, inspect the air vents for any obstructions. Clear away any items that may be blocking the airflow. Additionally, check the door gasket for any signs of damage or wear. If you notice any issues, consider replacing the gasket to ensure a proper seal.

Step 4: Check the Defrost Timer

Once the freezer is fully defrosted, locate the defrost timer. It is usually located behind the kickplate at the bottom front of the freezer. Use a screwdriver to remove the kickplate and access the defrost timer. If the timer is stuck or not functioning correctly, it may need to be replaced. Consult the user manual or contact Frigidaire customer support for specific instructions.

Step 5: Test the Defrost Heater

To test the defrost heater, you’ll need a multimeter. Disconnect the power supply to the freezer and locate the defrost heater, typically found underneath the evaporator coils. Remove the heater from its housing and use the multimeter to check for continuity. If there is no continuity, the defrost heater is faulty and needs to be replaced.

Step 6: Restore Power and Monitor

After completing the necessary repairs or replacements, plug the freezer back in and restore power. Set the temperature to the recommended level and closely monitor the freezer for the next few days. Ensure that the coils are not frosting excessively and that the freezer is maintaining the desired temperature.


Congratulations! You’ve successfully troubleshooted the frozen coil issue in your Frigidaire Freezer LFFH20F3QWC. By understanding the causes and following the step-by-step guide, you’ve taken the necessary steps to restore your freezer’s functionality. Remember, regular maintenance and proper usage can help prevent future coil freezing. If you encounter any further issues or have additional questions, don’t hesitate to reach out to Frigidaire’s customer support. Happy freezing (in a good way)!
