A snapping sound often indicates a frayed drive belt. In Coulsdon, 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.
The powerhouse of your system in Coulsdon is the Brushless DC Motor. 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 smooth motion.
False activations, known as random cycling, are common in Coulsdon due to weather interference. We calibrate Optex sensors to ignore interference. Crucially, we test the active infrared safety beams to ensure the door never closes on a pedestrian.
