John D Egg Harbor Township , NJ May 29, 2019 I had a cracked shelf in my GE refrigerator I pulled out the cracked shelf and laid it on the kitchen table. I laid the new shelf next to it, and one by one, moved each part from the old to the new. The whole process took about 15 minutes. I took it slow to make sure that I got it right. The new part was the exact unit for my refrigerator. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
