Screw-drive Genie opener is extremely loud; metal-on-metal screeching from rail.

Safety first: Disconnect power before working near the rail. Do not use flammable lubricants.

Steps:

• Clean screw: Wipe the exposed screw drive with a rag to remove old, dirty grease.
• Apply correct lubricant: Use Genie screw drive lubricant or manufacturer-approved equivalent. Apply a thin, even coat along the screw.
• Run opener: Reconnect power and run the door several times to distribute lubricant.
• Repeat periodically: Lubricate annually or as recommended to maintain quiet operation.
