LiftMaster High Door Friction or Weak Motor Output

Opener runs but door moves very slowly or struggles, especially in cold weather.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Thickened lubricant in cold, dry or rusted rollers, misaligned tracks, aging motor or capacitor

Safety: Do not increase force excessively to compensate for mechanical problems.

Inspect and lubricate: Clean old grease from tracks (if present) and lubricate rollers and hinges with cold-weather garage door lubricant.
Check track alignment: Ensure tracks are parallel and not pinching the rollers.
Test door balance: Door should move easily by hand; if not, have springs serviced.
Check capacitor: If the motor is weak even with a free-moving door, test and replace the motor capacitor.
