Morgan J Pittsburgh , PA March 20, 2016 Appliance: Model RF4287HAWP/XAA OR HABP/XAA The middle drawer slide was damaged and lost some ball bearings I replaced the rail-slide assembly. The repair wasn't difficult and took about 15 minutes. The only difficulty I had was finding the correct part. Samsung did not list the part at all based on my model number for a white refrigerator, so I had to look up the part number under the stainless steel model. The new part was identical to the old one in my fridge and works great! 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
