Dead remote fobs or wall switches typically trace back to moisture ingress in key barrels, failed receiver PCBs, or open safety edges.
Van Fix: We carry weatherproof armoured key switches, single/3-phase control PCBs, safety edges, and rolling-code fobs for instant repair.
Off-track curtains occur when sheared end-locks allow 75mm galvanized laths to slide sideways and jam inside the guide throat.
Van Fix: We secure the suspended curtain load, hydraulic-straighten bent U-channels, replace torn laths, and reset travel limits.
Forklift impacts and crowbar attacks crease bottom T-bars, twist steel side guides, and jam bullet lock pins.
Van Fix: Same-night curtain rebuilds across Tower Hamlets (E3) using stocked 75mm galvanized laths and bullet locks—no timber boarding needed.
Buzzing or clicking with zero lift points to capacitor capacitance loss, a seized brake solenoid, or sheared reduction gearing.
Van Fix: Stop pressing the switch to prevent winding burnout—we fit a new capacitor, 240V tubular motor, or 415V drive on site.
