False activations, known as phantom opening, are common in Twickenham due to weather interference. We calibrate Hotron 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 Twickenham, we replace these with steel-core timing 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 Twickenham 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.
