The powerhouse of your system in Witham is the High-Torque Drive Unit. When these fail, you might hear mechanical shuddering. We diagnose specific faults like stripped nylon gears and replace the unit with OEM parts to restore smooth motion.
False activations, known as random cycling, are common in Witham 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 Witham, we replace these with steel-core timing belts that resist stretching. We also inspect the carriage wheels. Replacing worn rollers eliminates friction, allowing the door to glide effortlessly.
