The core of your system in Tower Hill is the High-Torque Drive Unit. When these fail, you might hear excessive vibration. We diagnose specific faults like overheating windings and replace the unit with OEM parts to restore factory performance.
A snapping sound often indicates a worn toothed belt. In Tower Hill, 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 ghosting, are common in Tower Hill due to weather interference. We calibrate Hotron sensors to ignore interference. Crucially, we test the light curtain presence sensors to ensure the door reverses upon obstruction.
