James K Watertown , SD November 20, 2015 Appliance: Frigidaire Refrigerator MRT15DREW3 Frigidaire Refrigerator Mrt15drew3: Needed a new seal around a refrigerator door and replace a crisper shelf support. How to replace Crisper Shelf Support. To remove and replace the door seal the screws on the door panel had to be loosened. Then remove the seal and install the new one. Be sure the lip gets all the way behind the panel. Tighten the screws and your done. Replacing the shelf support went just the video showed. Tap the pin all the way in, remove the shelf bracket (mine was stuck so I had to tap on it). Fish out the pin and install the new bracket and tap the new pin in. All done. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
