The powerhouse of your system in Colliers Wood is the Brushless DC Motor. 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.
A snapping sound often indicates a frayed drive belt. In Colliers Wood, we replace these with steel-core timing belts that resist stretching. We also inspect the nylon rollers. Replacing worn rollers eliminates friction, allowing the door to glide effortlessly.
False activations, known as random cycling, are common in Colliers Wood 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.
