The Temperature Sensor is an OEM part for Frigidaire refrigerators. It monitors the internal temperature of the refrigerator and communicates with the control board to maintain the desired temperature settings. This sensor ensures that the refrigerator operates efficiently, keeping food at safe and optimal storage temperatures. Causes of a bad temperature sensor can include general wear and tear, exposure to moisture, or electrical issues. Over time, these factors can lead to inaccurate temperature readings or complete sensor failure. Symptoms of a bad Temperature Sensor include: The refrigerator not maintaining the set temperature Frequent cycling on and off of the cooling system Temperature fluctuations inside the refrigerator Error codes related to temperature control This OEM replacement is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore models.240597203 (AP4032998) replaces 1258948, 240597201, 240597202, 7240597203, AH1765215, EA1765215, PS1765215.
