Technical Diagnostics: Welwyn Hatfield Engineering
Quick Answer
Why is my door opening randomly?
This is often 'ghosting' caused by radar interference or sensor drift. In Welwyn Hatfield, we see this frequently with older analog sensors. We upgrade these to digital units that filter out environmental noise.
Component Analysis
