A snapping sound often indicates a frayed drive belt. In Totteridge, we replace these with reinforced Kevlar belts that resist stretching. We also inspect the hanger bearings. Replacing worn rollers eliminates drag, allowing the door to glide effortlessly.
False activations, known as phantom opening, are common in Totteridge due to electrical noise. We calibrate Optex sensors to ignore interference. Crucially, we test the light curtain presence sensors to ensure the door fails safe.
The core of your system in Totteridge is the Brushless DC Motor. 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 silent operation.
