Dawn B Auburn , PA March 14, 2016 The freezer kept defrosting too long and causing huge blocks of ice to form in the freezer We replaced the Temperature Sensor, and the Defrost Limiter Thermostat. Wasn't sure which was the problem, so we replaced both. After watching the video for the repair, it was fixed in 15 minutes, and is working good as new :-) 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
