Thomas C Green Bay , WI May 23, 2015 Appliance: General Electric Garbage Disposer GFC1000G01 Ge Disposer Gfc1000g01: Mounting ring broke from corrosion. How to replace Stopper. My thirty year old GE garbage disposal has been the best appliance I ever had. When the mounting ring broke from corrosion I remove it from the sink and started shopping for a new one. After the price and reviews of new comparable units I thought the GE unit I had looked in great shape. I entered the part numbers I needed and was directed to appliance parts pros found the parts at a great price including a diagram. Parts ordered on Sunday at my door on Wednesday good deal and good service. 9 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
