any more details on how to move the thermistors?

I have also noticed that the refrigerator temperature is not staying constant. Sometimes it will run 40 degree, sometimes it'll rise up to 50 or 60 degree Fahrenheit.

oh i see.

I just plugged the fridge back in today, and about 5-6 hours later, i noticed that the error came back on. I snapped  a picture. the red circle is the sensor that i changed

Disconnect the defrost controller at the plug connection and make sure the controller is not defective.  Use an ohm meter to check for continuity.  If everything is working fine, look at the connector on the back wall.  Does it look like there is some ice particle buildup inside the plug connector?  If so, use a hair dryer to melt the ice and dry it out completely.  You can use compressed air to blow away the water if available.

I hope that helps.

Good luck.
