A snapping sound often indicates a frayed drive belt. In Little Heath, 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.
The core of your system in Little Heath 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 smooth motion.
False activations, known as random cycling, are common in Little Heath 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.
