Technical Diagnostics: Gants Hill Engineering
Quick Answer
Why is my door opening randomly?
This is often 'ghosting' caused by radar interference or sensor drift. In Gants Hill, we see this frequently with older analog sensors. We upgrade these to digital units that filter out environmental noise.
Component Analysis
Drive Unit: The motor gearbox often suffers from stripped nylon gears. We replace the assembly to restore torque.
Safety Beams: We test the 'monitored' status of safety beams to ensure the door reverses immediately upon detecting an obstruction.
