The heart of your system in Colney Hatch is the High-Torque Drive Unit. When these fail, you might hear grinding noises. We diagnose specific faults like encoder positioning errors and replace the unit with OEM parts to restore factory performance.
A snapping sound often indicates a frayed drive belt. In Colney Hatch, we replace these with reinforced Kevlar belts that resist stretching. We also inspect the carriage wheels. Replacing worn rollers eliminates vibration, allowing the door to glide effortlessly.
