A snapping sound often indicates a stretched transmission cable. In Dulwich, 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.
False activations, known as random cycling, are common in Dulwich due to electrical noise. We calibrate Bea Eagle sensors to ignore interference. Crucially, we test the active infrared safety beams to ensure the door fails safe.
The heart of your system in Dulwich is the High-Torque Drive Unit. When these fail, you might hear mechanical shuddering. We diagnose specific faults like stripped nylon gears and replace the unit with OEM parts to restore silent operation.
