Replacement for Frigidaire 240597203 Refrigerator Temperature Sensor 12 Month Warranty & USA Support

Replacement for Frigidaire 240597203 Refrigerator Temperature Sensor

Restore accurate temperature monitoring in your refrigerator or freezer with the Wholesale Sensors Replacement for Frigidaire 240597203 Refrigerator Temperature Sensor. Designed for compatible Frigidaire, Electrolux, Kenmore, Crosley, and related appliances, this replacement thermistor provides the temperature feedback the appliance control system needs to maintain appropriate cooling conditions.

The 240597203 is part of a temperature sensor family that uses a 10K NTC thermistor. NTC stands for Negative Temperature Coefficient, meaning the electrical resistance of the sensing element changes predictably as temperature changes. The refrigerator’s electronic control system interprets this resistance to determine the temperature and manage cooling operation accordingly.

When the original temperature sensor becomes inaccurate or fails electrically, the refrigerator control system may receive incorrect temperature information. Depending on the appliance and sensor location, this can contribute to temperatures that are too warm or too cold, food freezing unexpectedly, inconsistent cooling, or other temperature-control problems.

The Wholesale Sensors replacement is engineered as a perfect OEM replacement that meets or exceeds OEM specifications for fit, function, temperature response, and electrical performance in compatible applications.

Replaces Frigidaire 240597203 and Related Part Numbers

The original 240597203 sensor has been replaced in Frigidaire’s current parts chain by 240597220. Sears PartsDirect identifies 240597220 as the manufacturer substitution for 240597203, while current Frigidaire parts references identify 240597220 as replacing several earlier versions.

Verified OEM replacement and cross-reference numbers include:

240597203
240597220
240597201
240597202
7240597203

Additional parts databases associate this sensor family with references including 1258948, 4985585, AP4032998, EAP17647917, EAP1765215, PS17647917, PS1765215, and PD00088922.

When searching for a replacement, seeing 240597220 instead of 240597203 is normal because the newer number supersedes the original sensor.

Compatible with Multiple Refrigerator Brands

This temperature sensor family is used across a wide selection of refrigerators manufactured within the Frigidaire and Electrolux appliance family.

Verified compatible brands include Frigidaire, Electrolux, Kenmore, and Crosley. Broader replacement-parts databases also identify applications involving select White-Westinghouse and other Frigidaire-built appliances.

Because appliance manufacturers can use different components even within the same product family, customers should always verify their complete refrigerator model number and original sensor part number before purchasing.

Popular Compatible Refrigerator Models

Verified compatible models include select:

FGTR1845QE3
LFUS2613LE0
FGHF2369ME4
GLHS68EGPW3
FRSS26L3AF5
E23BC68JPS3
EI23SS55HW0

The sensor family also fits numerous Kenmore 253-series refrigerators, including models such as 25344302400, 25344302401, 25344303400, 25344303401, 25344303402, 25344304400, and related configurations.

Additional compatible models exist, so this list should be treated as a sample rather than a complete fitment catalog.

Precision 10K NTC Temperature Sensing

Accurate temperature information is essential to refrigerator operation. The appliance control board depends on its temperature sensors to determine actual conditions inside the refrigerator, freezer, or evaporator area.

The current Frigidaire 240597220 replacement is specifically identified as a 10K NTC temperature sensor.

As temperature changes, the thermistor’s resistance changes. The appliance control system interprets this electrical signal and uses it as part of its cooling and temperature-management logic.

When a sensor begins providing incorrect resistance values, the control board may respond as though the refrigerator is warmer or colder than it actually is. This can cause cooling performance that does not match the temperature selected by the user.

Helps Correct Common Refrigerator Temperature Problems

A failed temperature sensor can produce several symptoms depending on the appliance and where the sensor is installed.

Current repair references specifically associate this sensor with correcting a refrigerator that is too warm or too cold.

Other temperature-related symptoms can include inconsistent cooling, unexpected freezing of refrigerated food, excessive cooling cycles, or inaccurate temperature regulation.

When used as an evaporator temperature sensor, incorrect sensor feedback can also interfere with the appliance’s ability to determine evaporator conditions. Repair documentation notes that a defective evaporator sensor can prevent the control board from correctly sensing whether the evaporator coil has been properly defrosted, potentially contributing to frost or ice accumulation.

Replacing a confirmed defective sensor can restore accurate temperature feedback and help the refrigerator control system operate as intended.

Important Refrigerator Troubleshooting Information

A refrigerator that is too warm or too cold does not automatically have a defective temperature sensor.

Similar symptoms can result from a failing evaporator fan, condenser problems, restricted airflow, damaged door seals, control board problems, defrost system failures, wiring problems, or other refrigeration components.

The temperature sensor can be checked with a multimeter to determine whether its resistance responds appropriately as temperature changes.

Proper diagnosis is recommended before replacing components, especially when troubleshooting an appliance that is completely unable to cool.

Durable Construction for Refrigerator and Freezer Environments

The Wholesale Sensors replacement is designed for continuous operation in the cold and moisture-prone environment found inside refrigerators and freezers.

The sensor incorporates a precision 10K NTC sensing element, protective probe housing, insulated wiring, and electrical connections designed for compatible refrigerator applications.

Available specifications for the 240597203 configuration identify a 10K Ohm NTC sensor with a compact probe designed for refrigerator temperature measurement.

Every Wholesale Sensors replacement temperature sensor is rigorously tested for resistance characteristics, temperature response, electrical performance, consistency, and reliability before shipment.

Straightforward Refrigerator Repair

Replacing a refrigerator temperature sensor is generally a manageable repair when the sensor location is accessible and the correct replacement has been identified.

Repair reports for the current replacement describe installation as relatively easy, with basic tools such as screwdrivers and nut drivers commonly used.

Before beginning installation, unplug the refrigerator or disconnect electrical power. Locate the existing temperature sensor according to the appliance’s service information, carefully disconnect the wiring connector, remove the original sensor, and install the replacement in the same position.

Sensor placement is important because the component must accurately measure temperature at its intended location.
