Carla S Raytown , MO July 31, 2015 Appliance: General Electric Refrigerator TBX21IIBRRWW Ge Refrigerator Tbx21iibrrww: Condenser fan blade broke when we were cleaning under the refrigerator. How to replace Blade Condenser Fan Assembly. It was fairly simple. The blade just slides onto the post of the condenser. Thanks to Appliance Pros, we should not have this problem again. We were offered to buy a special 28" long brush made to clean the refrigerator coils, and it works great! :) Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
