How to replace Refrigerator Temperature Sensor. For my version of the refrigerator, there is one screw that needs to be removed. I used a long screwdriver on each side to pry open the two lower tabs. There are two slits in the molded plastic so you do not ruin the housing. On mine, there are four tabs. The bottom two were pretty easy to release but the upper two were harder. Once the bottom two were released I slid in a flat putty knife between the panel and the door to release the upper two tabs. Then I unhooked the two wires leading to the old digital interface and removed the three screws on the back of the panel. Then I transferred over the black sticky icon label making sure that it’s got the filter and ice icons on the lower left and right. Then I reversed the process. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
