Important DIY Safety Notice

Basic maintenance tasks such as visual inspections, sensor wiping, and track cleaning are safe for homeowners. However, high-tension components including torsion springs, lift cables, bottom brackets, and winding cones store significant energy. Always request professional technician assistance for tensioned hardware repairs.

Common Questions

Troubleshooting FAQ

Answers to common owner questions regarding garage door maintenance and safety.

Torsion springs store high mechanical tension. Replacing them requires specialized winding bars and professional safety training. We strongly recommend professional technician installation to prevent injury or property damage. Read our broken spring guide for safety steps.
Never force the opener to lift a frozen door, as this can tear the rubber seal or strip the opener gears. Apply hot water or silicone spray along the bottom seal to melt ice, or gently scrape frozen ice away before opening. Read our frozen door guide.
A humming motor usually indicates a worn main drive gear, a jammed door track, or a broken torsion spring that prevents the motor from lifting the heavy weight. Read our humming opener guide.
