Quick Answer
Why is my door opening randomly?
This is often 'ghosting' caused by radar interference or sensor drift. In Crayford, 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.
Sensor Fusion: In Crayford, we recalibrate Microwave Radar for motion and Active Infrared for presence to prevent ghosting.
