A snapping sound often indicates a frayed drive belt. In Chiltern, we replace these with steel-core timing belts that resist stretching. We also inspect the hanger bearings. Replacing worn rollers eliminates friction, allowing the door to glide effortlessly.
False activations, known as phantom opening, are common in Chiltern due to weather interference. We calibrate Optex sensors to ignore interference. Crucially, we test the light curtain presence sensors to ensure the door fails safe.
The heart of your system in Chiltern is the High-Torque Drive Unit. When these fail, you might hear excessive vibration. We diagnose specific faults like stripped nylon gears and replace the unit with OEM parts to restore silent operation.
