False activations, known as phantom opening, are common in Sands End due to weather interference. We calibrate Optex sensors to ignore interference. Crucially, we test the active infrared safety beams to ensure the door reverses upon obstruction.
A snapping sound often indicates a worn toothed belt. In Sands End, we replace these with reinforced Kevlar belts that resist stretching. We also inspect the carriage wheels. Replacing worn rollers eliminates vibration, allowing the door to glide effortlessly.
The core of your system in Sands End is the Brushless DC Motor. 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 smooth motion.
