The thermistor on a Frigidaire refrigerator is located in the freezer section. It is generally found near the evaporator coil.
The thermistor plays a crucial role in regulating the temperature inside the refrigerator by sensing the air temperature and sending signals to the control board. It is a small sensor that measures the temperature and helps the refrigerator maintain the desired cooling level.
If there are temperature-related issues with your Frigidaire refrigerator, such as fluctuating temperatures or ice buildup, the thermistor could be a potential culprit. Identifying its location can help you troubleshoot problems and replace the faulty thermistor if needed.
By understanding the thermistor’s role and position, you can ensure your Frigidaire refrigerator functions efficiently and keeps your food fresh for longer.
Importance Of The Thermistor
The thermistor is a crucial component in your Frigidaire refrigerator that plays a vital role in maintaining optimal temperature control. As a small but powerful sensor, the thermistor helps regulate the cooling system, ensuring your fridge maintains consistent and safe temperature levels. Understanding the role and importance of the thermistor is essential for troubleshooting and keeping your refrigerator running smoothly.
Role Of The Thermistor In A Frigidaire Refrigerator
In a Frigidaire refrigerator, the thermistor serves as the temperature sensor. It measures the air temperature inside the fridge and relays this information to the control board. The control board then adjusts the cooling system accordingly to maintain the desired temperature. The thermistor acts as a feedback device, constantly monitoring the temperature and providing valuable data to the refrigerator’s control system.
Importance Of The Thermistor In Maintaining Temperature Control
Temperature control is vital in refrigerators to ensure food safety and preservation. The thermistor helps achieve this by accurately monitoring the temperature and allowing the control board to make necessary adjustments. Without a properly functioning thermistor, your refrigerator could experience temperature fluctuations that may lead to spoilage or freezing of food items.
By sensing any temperature deviations from the set target, the thermistor prompts the control board to activate the cooling system or defrost cycle, helping to maintain a stable temperature inside the fridge. This precise temperature control reduces energy consumption, prevents excessive ice buildup, and facilitates optimal food storage conditions.

Understanding The Thermistor
In a Frigidaire refrigerator, the thermistor plays a vital role in maintaining the optimal temperature inside the appliance. Understanding what a thermistor is and how it functions can help you troubleshoot temperature-related issues and ensure the smooth operation of your refrigerator.
Explanation Of What A Thermistor Is
A thermistor is a temperature-sensing device that measures and regulates temperature within a specific range. It consists of a resistor made from semiconductor material with electrical resistance that varies with temperature changes. The word ‘thermistor’ is derived from the combination of ‘thermal’ and ‘resistor.’
The resistance of a thermistor decreases as temperature rises, allowing it to control the refrigerator’s cooling system. By monitoring the temperature, the thermistor provides feedback to the refrigerator’s control board, enabling it to adjust cooling cycles accordingly.
How The Thermistor Works In A Refrigerator
The thermistor in a Frigidaire refrigerator is typically located near the evaporator coil, which is responsible for cooling the air inside the appliance. It measures the temperature in this area and sends the information to the control board. This data enables the control board to determine whether the cooling cycle needs adjustment to maintain the desired temperature.
When the refrigerator’s compressor starts, the evaporator fan draws air over the evaporator coil, which cools the air. The thermistor measures the temperature of this cooled air before it is circulated throughout the refrigerator to keep the stored food fresh. If the temperature deviates from the set point, the thermistor triggers the control board to adjust the cooling cycles accordingly, optimizing energy efficiency and preserving the quality of the stored food.
Different Types Of Thermistors Used In Frigidaire Refrigerators
Frigidaire refrigerators use different types of thermistors, depending on the model and specific temperature-sensing requirements. The two most commonly used thermistors in Frigidaire refrigerators are:
| Thermistor Type | Function |
| NTC Thermistors | Negative Temperature Coefficient (NTC) thermistors are the most common type used in Frigidaire refrigerators. These thermistors have a higher resistance at lower temperatures and lower resistance at higher temperatures, allowing for accurate temperature sensing. |
| PTC Thermistors | Positive Temperature Coefficient (PTC) thermistors have a resistance that increases with rising temperature. In some Frigidaire refrigerator models, PTC thermistors are used for specific temperature regulation purposes, such as defrost cycle control. |
These different types of thermistors ensure precise temperature monitoring and control throughout the refrigerator, ensuring optimal performance and food preservation.
Locating The Thermistor In A Frigidaire Refrigerator
If you are experiencing issues with your Frigidaire refrigerator, such as improper cooling or temperature fluctuations, it might be time to check the thermistor. The thermistor is a vital component that helps regulate the temperature inside the refrigerator.
Common Placement Of The Thermistor In Frigidaire Refrigerators
The thermistor in Frigidaire refrigerators is typically located near the evaporator coil, which is responsible for cooling the air inside the fridge. The exact placement may vary depending on the specific model and make of your refrigerator. However, you can generally find the thermistor in one of the following common positions:
- Clip-on thermistor attached to the evaporator coil: In some Frigidaire refrigerator models, the thermistor is clipped onto the evaporator coil. This placement ensures that the temperature readings are accurate and responsive to changes in the cooling process.
- In-line thermistor within the air duct: Another common placement is installing the thermistor within the air duct. This position allows the thermistor to monitor the temperature of the air that circulates within the refrigerator compartment.
- Mounted thermistor on the refrigerator wall: Frigidaire refrigerators may also have the thermistor mounted on the inner wall of the refrigerator. This placement allows the thermistor to monitor the overall temperature inside the fridge.
