False activations, known as phantom opening, are common in Rayleigh 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.
A snapping sound often indicates a worn toothed belt. In Rayleigh, we replace these with steel-core timing belts that resist stretching. We also inspect the hanger bearings. Replacing worn rollers eliminates drag, allowing the door to glide effortlessly.
The heart of your system in Rayleigh is the High-Torque Drive Unit. When these fail, you might hear excessive vibration. We diagnose specific faults like stripped nylon gears and replace the unit with OEM parts to restore smooth motion.
