Common Trade Diagnostic Faults
Busy high-street shops in Crayford regularly need immediate repair of faulty automatic door sensors.
- Break-out system limit switches misaligned, halting high-traffic entrance cycles altogether.
- Concealed transom systems grinding and binding because internal gear spindles dropped beneath standard clearance parameters.
- Automatic commercial doors lingering open or halting midway through sliding cycles due to internal logical loops.
