Frigidaire Refrigerator Ffss2315Ts0 Not Defrosting

Title: Frigidaire Refrigerator FFSS2315TS0 Not Defrosting

Have you ever opened your refrigerator only to find a layer of frost covering your food? It can be frustrating, especially when you rely on your refrigerator to keep your groceries fresh. One common issue that many Frigidaire refrigerator owners face is the problem of the FFSS2315TS0 model not defrosting properly. In this article, we will explore the possible causes of this issue and provide you with some troubleshooting steps to help you resolve it. So, let’s dive in and get your refrigerator back to its optimal functioning!

1. Understanding the Defrosting Process:

Before we delve into the reasons behind your Frigidaire refrigerator not defrosting, let’s first understand how the defrosting process works. Refrigerators have a built-in defrost system that prevents ice buildup on the evaporator coils. This system consists of a defrost heater, a defrost thermostat, and a defrost timer or control board. The defrost thermostat monitors the temperature of the evaporator coils, and when it reaches a certain level, it signals the defrost heater to turn on and melt any ice or frost that has accumulated. The defrost timer or control board regulates the frequency and duration of the defrost cycle.

2. Possible Causes of Frigidaire Refrigerator FFSS2315TS0 Not Defrosting:

Now that we have a basic understanding of the defrosting process, let’s explore some common causes for your Frigidaire refrigerator not defrosting:

a) Faulty Defrost Timer/Control Board:
One possible cause could be a defective defrost timer or control board. If these components malfunction, the defrost cycle may not initiate, leading to ice buildup on the evaporator coils. Consider checking these parts for any signs of damage or malfunction.

b) Defective Defrost Heater:
A faulty defrost heater can also prevent the defrosting process from occurring. If the heater fails to turn on or does not generate enough heat, the ice on the coils will not melt. Inspect the defrost heater for any visible signs of damage or test it with a multimeter to check its continuity.

c) Malfunctioning Defrost Thermostat:
The defrost thermostat plays a crucial role in determining when the defrost cycle should start and end. If the thermostat is faulty, it may not send the signal to initiate the defrosting process. Test the defrost thermostat for continuity or consult a professional to ensure its proper functioning.

d) Clogged or Frozen Defrost Drain:
A clogged or frozen defrost drain can also cause your Frigidaire refrigerator not to defrost. When the defrost cycle occurs, the melted ice should flow into the drain pan. If the drain is blocked or frozen, the water will accumulate and freeze, leading to ice buildup on the coils. Clear any obstructions from the drain or use a hairdryer to thaw the frozen drain.

3. Troubleshooting Steps to Resolve the Issue:

Now that we have identified some possible causes, let’s move on to troubleshooting steps to help you resolve the issue:

Step 1: Unplug the Refrigerator:
To ensure your safety, unplug the refrigerator from the power source before performing any troubleshooting steps.

Step 2: Check the Defrost Timer/Control Board:
Inspect the defrost timer or control board for any visible signs of damage or burning. If you notice any issues, consider replacing the faulty component.

Step 3: Test the Defrost Heater:
Using a multimeter, test the defrost heater for continuity. If it fails the continuity test, it is likely defective and needs to be replaced.

Step 4: Check the Defrost Thermostat:
Test the defrost thermostat for continuity. If it does not show continuity at freezing temperatures, it may be faulty and should be replaced.

Step 5: Clear the Defrost Drain:
Inspect the defrost drain for any clogs or ice buildup. Use a hairdryer to thaw the frozen drain or clear any obstructions that may be blocking the flow of water.

Step 6: Monitor the Refrigerator:
After performing the troubleshooting steps, plug the refrigerator back in and monitor its performance. Check if the defrost cycle initiates and if the ice buildup on the coils reduces over time.


Dealing with a Frigidaire refrigerator FFSS2315TS0 that is not defrosting can be a frustrating experience. However, by understanding the defrosting process and identifying the possible causes, you can troubleshoot the issue and get your refrigerator back to its optimal functioning. Remember to follow the troubleshooting steps mentioned in this article and consult a professional if needed. With a little effort and patience, you can enjoy a frost-free refrigerator once again. Happy troubleshooting!
