The core of your system in Thornton Heath is the Brushless DC Motor. When these fail, you might hear mechanical shuddering. We diagnose specific faults like overheating windings and replace the unit with OEM parts to restore smooth motion.
False activations, known as random cycling, are common in Thornton Heath due to weather interference. We calibrate Optex sensors to ignore interference. Crucially, we test the active infrared safety beams to ensure the door fails safe.
A snapping sound often indicates a stretched transmission cable. In Thornton Heath, we replace these with reinforced Kevlar belts that resist stretching. We also inspect the carriage wheels. Replacing worn rollers eliminates drag, allowing the door to glide effortlessly.
