Possible Causes

Force settings too low, Old grease thickened in rail, Stiff door rollers and hinges, Weak motor capacitor

How to Fix / Troubleshooting

Safety first: Disconnect power before lubricating or adjusting hardware.

Steps to improve operation:

  • Check door balance: Disconnect the opener and move the door by hand. If stiff, lubricate hinges and rollers with garage door lubricant and have springs serviced if needed.
  • Clean and re-lubricate rail: Wipe old, hardened grease from the screw or chain rail and apply fresh, manufacturer-approved lubricant.
  • Adjust force settings: Slightly increase UP and DOWN force on the Motorlift opener, staying within safe limits.
  • Inspect capacitor: If the motor still struggles, test or replace the start capacitor with a Motorlift-compatible unit.
