Technical Diagnostics: Forty Hill Engineering
Quick Answer
Why is my door opening randomly?
This is often 'ghosting' caused by radar interference or sensor drift. In Forty Hill, we see this frequently with older analog sensors. We upgrade these to digital units that filter out environmental noise.
Component Analysis
Operator Mechanics: We inspect the DC motor for overheating and replace worn brushes or the entire brushless unit if efficiency drops.
Sensor Fusion: In Forty Hill, we recalibrate Microwave Radar for motion and Active Infrared for presence to prevent ghosting.
