Jonathan P West Hills , CA September 06, 2025 Appliance: General Electric Refrigerator PFSS6PKXASS Ge Refrigerator Pfss6pkxass: Ice maker knocking sound. How to replace Icemaker Assy. Our GE Profile Refrigerator Ice Maker kept making a knocking sound which I believe was the auto-shutoff trying to disengage— we weren’t getting any ice. Ordered the part, took the old out and fastened the connection. Very easy fix. Thank you. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
