Fridge Not Holding Temperature? Frigidaire Refrigerator Sensor 240597220 – Fix Incorrect Temp Fast

If your Frigidaire refrigerator is running too warm, too cold, or cycling erratically, a failed temperature sensor is the most common cause. In most Frigidaire and Electrolux refrigerators, this is caused by a failed thermistor/temperature sensor. When it fails, the control board receives inaccurate readings and cannot regulate the compressor or evaporator fan correctly — leading to food spoilage, frost buildup, or a compressor that runs non-stop. ⚡ Common failure point in Frigidaire-built refrigerators from the early 2000s onward. Part 240597220 is the genuine OEM replacement that restores accurate temperature sensing and normal refrigeration cycles immediately.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ QUALIFIER 1 — refrigerator powers on and compressor runs
• ✔ QUALIFIER 2 — fans and lights work normally
• ✔ QUALIFIER 3 — no error codes pointing to a control board or defrost issue
• ✔ ONLY problem is incorrect or unstable cabinet temperature

🔧 Common Symptoms

• Refrigerator section too warm or too cold despite correct thermostat setting
• Compressor runs constantly or short-cycles
• Frost or ice buildup in the fresh food section
• Control board displaying temperature error codes (e.g. SY EF, H1)

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing this temperature sensor restores normal operation immediately.
