A snapping sound often indicates a frayed drive belt. In Belsize Park, we replace these with reinforced Kevlar belts that resist stretching. We also inspect the hanger bearings. Replacing worn rollers eliminates drag, allowing the door to glide effortlessly.
False activations, known as ghosting, are common in Belsize Park due to reflective surfaces. We calibrate Optex sensors to ignore interference. Crucially, we test the light curtain presence sensors to ensure the door reverses upon obstruction.
The core of your system in Belsize Park is the High-Torque Drive Unit. When these fail, you might hear mechanical shuddering. We diagnose specific faults like encoder positioning errors and replace the unit with OEM parts to restore silent operation.
