Title: Frigidaire Refrigerator FFHS2622MSF Not Defrosting

Have you recently noticed that your Frigidaire refrigerator model FFHS2622MSF is not defrosting properly? Don’t worry, you’re not alone! A malfunctioning defrost system can be a common issue with refrigerators, but it doesn’t have to be a cause for panic. In this blog post, we will explore the possible causes of this problem and provide you with some simple troubleshooting steps to help you get your refrigerator back to its optimal performance. So, let’s dive in and unravel the mystery behind your Frigidaire refrigerator’s defrosting issue!

Understanding the Defrost System

Before we delve into the troubleshooting steps, it’s important to understand how the defrost system in your Frigidaire refrigerator works. The defrost system is responsible for preventing the buildup of ice on the evaporator coils, which can hinder the cooling process. It consists of three main components: the defrost timer, the defrost heater, and the defrost thermostat.

The defrost timer controls the timing of the defrost cycle, activating the defrost heater to melt any accumulated ice on the coils. The defrost thermostat, on the other hand, monitors the temperature of the evaporator coils. If the coils become too cold, the defrost thermostat signals the defrost heater to turn on and melt the ice. This cycle repeats periodically to ensure efficient cooling.

Possible Causes of Defrosting Issues

Now that we have a basic understanding of the defrost system, let’s explore some of the possible causes for your Frigidaire refrigerator FFHS2622MSF not defrosting:

1. Faulty Defrost Timer: If the defrost timer is defective, it may not be activating the defrost cycle at the appropriate intervals. This can lead to excessive ice buildup on the evaporator coils and hinder the refrigerator’s cooling performance.

2. Malfunctioning Defrost Heater: A malfunctioning defrost heater may not be able to generate enough heat to melt the ice on the coils. This can result in ice accumulation, leading to inadequate cooling and potential damage to the refrigerator’s components.

3. Defective Defrost Thermostat: If the defrost thermostat is faulty, it may not be able to accurately monitor the temperature of the evaporator coils. As a result, the defrost heater may not turn on when needed, causing ice buildup and poor cooling performance.

4. Blocked Air Vents: Blocked air vents can restrict the flow of cold air from the freezer to the refrigerator compartment. This can cause the evaporator coils to freeze over, leading to defrosting issues.

Troubleshooting Steps

Now that we have identified some potential causes, let’s move on to the troubleshooting steps to help you resolve the defrosting issue with your Frigidaire refrigerator FFHS2622MSF:

Step 1: Check the Defrost Timer

Locate the defrost timer, usually found behind the refrigerator’s kick plate or inside the control panel. Rotate the timer manually to see if it advances the defrost cycle. If it doesn’t, the defrost timer may be faulty and needs to be replaced.

Step 2: Inspect the Defrost Heater

Carefully examine the defrost heater for any signs of damage or malfunction. If you notice any visible defects, such as burned-out sections or broken wires, it’s likely that the defrost heater needs to be replaced.

Step 3: Test the Defrost Thermostat

Using a multimeter, test the defrost thermostat for continuity. If the multimeter shows no continuity, the defrost thermostat is defective and should be replaced.

Step 4: Clear Blocked Air Vents

Inspect the air vents in both the freezer and refrigerator compartments. If you find any obstructions, such as food items or ice, clear them to ensure proper airflow.

Step 5: Call a Professional

If the above troubleshooting steps don’t resolve the issue, it’s advisable to seek assistance from a qualified technician. They will have the expertise to diagnose and fix complex defrosting problems.


Dealing with a Frigidaire refrigerator FFHS2622MSF that is not defrosting can be frustrating, but with the right knowledge and troubleshooting steps, you can tackle the issue effectively. Remember to check the defrost timer, inspect the defrost heater and thermostat, clear any blocked air vents, and seek professional help if needed. By following these steps, you can restore your refrigerator’s defrosting functionality and ensure its optimal performance. Don’t let ice buildup ruin your cooling experience – take action and get your Frigidaire refrigerator back on track!
