Michael L Shelbyville , KY November 28, 2017 Appliance: Roper Refrigerator RT14BKXKQ02 Roper Refrigerator Rt14bkxkq02: Freezer icing up. How to replace Timer. Replaced the heater element and the timer. The timer was fine but I figured I should replace both while doing it. Getting all the ice melted is what took the longest. Replacing the parts took approx. 30 minutes. 7 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
