Arnold K Punta Gorda , FL November 08, 2018 Appliance: Model RF20HFENBSP/AA (0000) Water and ice build up inside the refrigerator Knowing from a previous repair, that there was only 3 parts that could be bad. I decided if I was going to take it apart to change all 3. Not having the proper test equipment, it was cheaper to replace the 3 parts than pay a repair person. 17 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
