A malfunctioning garage door motor was identified as the root cause of operational issues. I began by safely disconnecting the power supply to ensure safety during the replacement process. The old LiftMaster belt drive motor was carefully removed, paying attention to the alignment and positioning of the belt and associated components. A new LiftMaster belt drive motor was then installed, ensuring all connections and adjustments were made precisely. The belt was reattached, and the motor was tested to confirm smooth and efficient operation. The door was thoroughly inspected for any signs of strain or misalignment, and adjustments were made as necessary. The power was reconnected, and the door was tested multiple times to ensure it functioned correctly under various conditions. The job was completed to the client's satisfaction, restoring reliable and quiet operation to their garage door system.
