Ron for Model Number RF4287HARS I had ice in the back of the refrigerator so I removed the back panel, cleared the ice and replaced the defrost sensor as the resistance was about 10x what it should be. Now the fridge cools and fan works but other than the very back of the refrigerator the temperature only reaches 50 degrees, any idea what it could be. Also where does the temperature reading on the digital display come from, the defrost sensor or is there one somewhere else.

If it is a sealed system then you will need an EPA certified technician for those repairs. Read More... Answered by AppliancePartsPros.com | Wednesday, February 17, 2021
