Mary M Los Altos , CA April 04, 2021 Appliance: Frigidaire Refrigerator MRT15CNBW1 Frigidaire Refrigerator Mrt15cnbw1: The door shelf supports had broken off. How to replace Door Shelf Support-Rh. I replaced both supports, using the parts I ordered from your website. At first, I was not successful, but I saw a Q & A on your website that indicated that the supports have to be pushed down HARD (even if seems like they might break). They didn't break and now the shelf is functional once more. Thanks! Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
