Noise and slow travel are usually mechanical: a dirty or damaged track, worn carriage rollers or a loose or cracked drive belt. Sand and grit are common in the UAE and wear rollers quickly. Less often, a low power supply or a poor setting on the control unit slows the door. Cleaning the track and replacing worn rollers often restores smooth travel. Continuing to run a door that grinds can damage the belt and the motor, so book a check early.
