A snapping sound often indicates a stretched transmission cable. In Sandy, we replace these with reinforced Kevlar belts that resist stretching. We also inspect the carriage wheels. Replacing worn rollers eliminates friction, allowing the door to glide effortlessly.
False activations, known as random cycling, are common in Sandy 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 core of your system in Sandy 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 smooth motion.
