A snapping sound often indicates a stretched transmission cable. In Nunhead, we replace these with steel-core timing belts that resist stretching. We also inspect the nylon rollers. Replacing worn rollers eliminates drag, allowing the door to glide effortlessly.
False activations, known as ghosting, are common in Nunhead due to electrical noise. We calibrate Optex sensors to ignore interference. Crucially, we test the active infrared safety beams to ensure the door reverses upon obstruction.
The core of your system in Nunhead 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 factory performance.
