Unplugged frig, removed shelves to get back panel off inside the frig compartment using a screwdriver and replaced temp sensor(part #DA32-00011C) located at the top left side. The sensor has a yellow cord, white tip, and blue plug and it was plugged in behind panel at the top left side and threaded through a clip up over the top of the black fan inside the panel and the white tip was stuffed through some styrofoam that faced the front center vent. I had to dig around a bit to pull out the old sensor from that styrofoam and place the new one. After replacing the sensor and plugging the frig back in I watched the outer display go back down to the temperature I had programmed (39 degrees). I even bought a temperature gauge to ensure the display was correct and it is still holding steady. Saved me from having to buy a whole new refrigerator.
