A snapping sound often indicates a stretched transmission cable. In City Of London, we replace these with steel-core timing belts that resist stretching. We also inspect the nylon rollers. Replacing worn rollers eliminates vibration, allowing the door to glide effortlessly.
The heart of your system in City Of London is the High-Torque Drive Unit. When these fail, you might hear mechanical shuddering. We diagnose specific faults like overheating windings and replace the unit with OEM parts to restore smooth motion.
