How to Troubleshoot & Replace Frigidaire AP7243155 / 240597220 Refrigerator Temperature Sensor

With the excellent from the staff at appliance parts pro, the diagnoses was correct and the fix was easy. 

I have used AP Pros.com in the past. They've always been helpful. I used the live chat feature to describe the symptoms (freezer was fine, fridge was too cold, water filter/line frozen) and she made recommendations and showed me exploded view PDF's of the location of each part. I ordered the Damper Assembly (expensive) and Temp Sensor (not expensive) and installed both parts in about 30 mins after watching the instructional videos on the website. Violia! Worked like a charm. It's always a bummer to spend $250 or more on parts for a $1000 fridge, but AP Pros.com had what I needed, shipped it out quickly and educated me on what needed to be repaired. Thank you! Matt, Monroe, WA 

I removed each component within a few minutes and replaced 

I replaced the defrost heater and thermostat and it seems like everything is working fine now. The defrost heater was not working and the fresh section of my refrigerator was getting hot, it wouldn’t cool. Thanks 

Ordered Temp Sensor 

With the help of Appliance Parts Pros technician, I was able to diagnose the faulty part which turned out to be the main board. There was a video on the website which helps me replace the parts in under 30 minutes. 

Turned off the power, removed the sensor cover, unclipped the sensor and snapped in the new one. 

I ordered and replaced the thermistor which controls temperature and voltage for the fridge. 

I replaced the thermistor after online chatting with AppliancePartsPrros.com.
