A snapping sound often indicates a worn toothed belt. In Bexley, we replace these with reinforced Kevlar belts that resist stretching. We also inspect the nylon rollers. Replacing worn rollers eliminates drag, allowing the door to glide effortlessly.
False activations, known as phantom opening, are common in Bexley due to weather interference. We calibrate Hotron sensors to ignore interference. Crucially, we test the light curtain presence sensors to ensure the door reverses upon obstruction.
The powerhouse of your system in Bexley is the High-Torque Drive Unit. When these fail, you might hear excessive vibration. We diagnose specific faults like encoder positioning errors and replace the unit with OEM parts to restore silent operation.
