Garage door opener operates, but the door moves very slowly or struggles, especially in cold weather.

Safety first: Do not attempt to adjust torsion springs yourself. Disconnect power before lubricating or tightening hardware.

Steps to improve movement:

• 1. Manually test door: Disconnect the opener and move the door by hand. If it is heavy or jerky, the problem is with the door, not the opener.
• 2. Lubricate moving parts: Apply a silicone-based garage door lubricant to rollers, hinges, and bearings. Wipe off excess.
• 3. Remove excess grease: If the tracks or rail are coated with thick grease, clean them with a rag. Use only light lubrication where recommended by Stanley.
• 4. Have springs serviced: If the door will not stay halfway open by itself, call a professional to adjust or replace springs.
• 5. Adjust force slightly: After mechanical issues are corrected, increase the opener’s up and down force slightly if needed, staying within safe limits.
