If you own a Frigidaire side-by-side refrigerator, chances are you’ve enjoyed its convenience and reliable performance. However, like all appliances, issues may arise, particularly with the thermistor—a small yet crucial component responsible for temperature regulation. When your refrigerator starts showing signs of temperature inconsistencies, it may be time to consider replacing the thermistor. This comprehensive guide will walk you through the process step-by-step, ensuring a smooth and effective replacement operation.
Understanding the Thermistor’s Role
Before delving into the replacement process, it’s important to understand what the thermistor does.
What is a Thermistor?
A thermistor is a temperature sensor with resistance that changes according to temperature fluctuations. In a refrigerator, it plays a vital role in monitoring the internal temperature and transmitting this information to the control board, which adjusts the cooling cycle accordingly.
Why Replace the Thermistor?
Several signs indicate that your thermistor may need replacing:
- Inconsistent temperature: Items in your refrigerator may freeze or, conversely, may not stay cold enough.
- Error codes: Modern Frigidaire models may display error codes corresponding to thermistor issues.
- Frequent cycling: Your refrigerator may frequently turn on and off.
Recognizing these signs is the first step toward the necessary repairs.
Preparing for the Replacement
Before you begin the replacement process, preparation is key. Let’s gather the tools and materials you’ll need.
Tools and Supplies Required
- Screwdriver set: A variety of Phillips and flat-head screwdrivers.
- Nut driver: Size ¼ inch is commonly required.
- Pliers: Standard pliers will work for gripping wires and connectors.
- Replacement Thermistor: Ensure you have the correct part for your refrigerator model.
Safety First
Always prioritize safety when working with electrical appliances. Begin the process by unplugging the refrigerator from the wall outlet to avoid electrical shock.
Step-by-Step Guide to Replacing the Thermistor
Now that you’ve prepared yourself and gathered the necessary tools, let’s delve into the replacement procedure. Follow these steps to successfully replace the thermistor in your Frigidaire side-by-side refrigerator.
Step 1: Locating the Thermistor
The first task is to find the thermistor within your refrigerator. Typically, the thermistor is located in the following areas:
- In the freezer compartment: Often near the evaporator fan or on the evaporator cover.
- Refrigerator compartment: It may be found in the back wall near the control panel.
Refer to your user manual for exact specifications pertaining to your model.
Step 2: Disassembling the Necessary Components
Once you’ve located the thermistor, you may need to remove some components to access it completely.
Removing the Cover Panel
- Use your screwdriver or nut driver to remove the screws securing the cover panel.
- Gently pull away the panel to expose the thermistor and its wiring.
Disconnecting the Thermistor
- Carefully detach the thermistor by unplugging it from the wiring harness. Take care not to damage the connectors, as they are delicate.
- If there’s any adhesive or tape securing the thermistor in place, gently peel it away.
Step 3: Installing the New Thermistor
Now that you’ve removed the old thermistor, it’s time to install the new one. Follow these steps:
Connecting the New Thermistor
- Push the new thermistor into the same slot where the old one was located.
- Reconnect it to the wiring harness, ensuring a secure fit.
Reattaching the Cover Panel
- Align the cover panel back into place.
- Secure it using the screws you had previously removed.
Step 4: Testing Your Refrigerator
With the new thermistor installed and everything reassembled, it’s time to plug your refrigerator back in.
- Turn on your refrigerator and allow it to run for a few hours.
- Monitor the temperature settings and ensure they stabilize at the desired levels.
Final Checks
During your monitoring:
- Look for any unusual sounds.
- Observe if the compressor cycles appropriately.
- Check if there are any error codes or indicators on your refrigerator.
If all operates smoothly, congratulations! You’ve successfully replaced the thermistor.

What is a thermistor, and what role does it play in my Frigidaire side-by-side refrigerator?
A thermistor is a type of temperature sensor that measures and regulates the internal temperature of your refrigerator. In a Frigidaire side-by-side refrigerator, the thermistor communicates with the main control board, providing crucial information about the temperature inside various compartments. This information is essential for ensuring that the refrigerator maintains optimal conditions for food preservation.
If the thermistor malfunctions or becomes faulty, it can lead to incorrect temperature readings. This could result in your refrigerator being too warm or too cold, which can spoil food or create ice buildup. Understanding the importance of the thermistor can help you recognize the signs of a failing component and take action to replace it effectively.
What are the symptoms indicating that my thermistor needs replacement?
There are several symptoms that may indicate a failing thermistor in your refrigerator. One common sign is inconsistent temperatures throughout the refrigerator and freezer sections. If you’re noticing food items freezing in the refrigerator section or your freezer isn’t maintaining its designated low temperature, it’s time to evaluate the thermistor’s functionality.
Another symptom to watch for is the refrigerator’s frequent cycling on and off. If the compressor runs continuously or you hear unusual noises, these could be indicators of a failing thermistor. Keeping an eye out for these symptoms can help prevent food spoilage and other issues related to temperature regulation.
How do I determine if the thermistor is faulty?
To determine if the thermistor in your refrigerator is faulty, you can start by using a multimeter to measure its resistance. Disconnect the thermistor from the control board and set your multimeter to measure ohms. The resistance value should correspond to the temperature—typically a lower resistance indicates a warmer temperature while a higher resistance indicates a cooler temperature. Comparing these readings with the manufacturer’s specifications can confirm if the thermistor is indeed malfunctioning.
Another method involves visually inspecting the thermistor for any damage or signs of wear. Look for frayed wiring, corrosion, or any physical damage that might interfere with its operation. If both tests point to a problem, replacing the thermistor is likely the best course of action.
What tools do I need to replace the thermistor in my Frigidaire refrigerator?
To successfully replace the thermistor in your Frigidaire side-by-side refrigerator, you will need a few essential tools. Firstly, a screwdriver will be necessary to remove any screws that secure the thermistor or its housing in place. Depending on the model, you may need a Phillips or flat-head screwdriver, so ensure you have both types on hand.
In addition to a screwdriver, having a multimeter is crucial for diagnosing the thermistor’s functionality. A pair of needle-nose pliers may also be helpful to grip and manipulate wires or connectors that are difficult to reach. Lastly, a flashlight can assist you in thoroughly inspecting the area around the thermistor, making it easier to spot any issues or components that need attention.
Is replacing the thermistor a DIY job, or should I hire a professional?
Replacing a thermistor can be a DIY job for those who are comfortable with basic electrical components and tools. If you feel confident using a multimeter and have experience with home repair tasks, you can follow the manufacturer’s guidelines to remove the faulty thermistor and replace it with a new one. Many people find this process manageable, especially with online resources and videos available to guide them.
However, if you are unsure about any aspect of the replacement process or lack the required tools, it may be best to consult a professional. Hiring an experienced technician can save you time, ensure the job is done correctly, and prevent potential damage to the refrigerator during the process. Always weigh your confidence and capabilities against the complexity of the task when deciding whether to go the DIY route or seek professional help.
Where can I find a replacement thermistor for my Frigidaire refrigerator?
Replacement thermistors can be found through various retailers that specialize in appliance parts. Your options include local appliance repair shops, big-box home improvement stores, or online marketplaces. Websites like Amazon, eBay, and manufacturer-specific online stores often carry parts for many refrigerator models, including the Frigidaire side-by-side units.
