Kenneth P Ocala , FL March 23, 2020 Appliance: Frigidaire Microwave FGMV174KFB Frigidaire Microwave Fgmv174kfb: Microwave door latch. How to replace Latch. It was extremely simple. We had reviewed a video and with the right parts on hand we had it fixed in under 15 minutes. Probably saved us over $500.00 with the purchase of a new microwave and installation. Thank You very much!!! 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
