Denis C Hilton , NY July 22, 2019 Appliance: General Electric Refrigerator PFSS6PKWBSS Ge Refrigerator Pfss6pkwbss: Water flow to ice maker and door dispenser at a trickle. How to replace Cage Roller Bearing Assembly. Replaced refrigerator filter with the bypass plug. Water still at a trickle so the filter was not the problem. Turned water off, disconnected water line at the top of the water valve, tested flow. Still a trickle. So the water filter head was not letting full water flow through it anymore. Replaced the water filter head, now the water flows over 2 times as fast as before. Like a new refrigerator. Ice cubes are now back to their normal large size. Took about 1/2 hour. The hardest part was figuring out how to remove the cover on the water filter head. Used a mirror laying on the refrigerator shelf so I could see how to unhook the cover from the filter hear. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
