The door stops short of the floor and leaves a gap at the bottom
Why it happens
The down travel limit decides where the door stops on the way down. It can drift over time, or be left where it was when a motor head was swapped.
Why it matters
A door that stops short isn't closed. Wind-blown sand and rain get in, and so can anyone who wants to.
Response
Thom checks where the door meets the floor against where the limit is stopping it, resets the limit, then rechecks the force and the safety reversal.
