What a Safety Inspection Actually Tests

Photo eyes and entrapment protection became mandatory on new residential openers in the early 1990s. Plenty of Schaumburg homes still have the original unit from before that, with no sensors at the floor and only a crude force reversal that depends on the mechanism being in good order.

That is worth understanding rather than panicking about, and it does not automatically mean a new opener. What it does mean is that the mechanical reversal has to be verified carefully and the household has to know what the door will and will not do. It also makes that opener a poor candidate for remote phone control, since closing a door you cannot see is only sensible on one that detects what is underneath it.

Cables get followed the full run. The area to watch is low down at the bottom bracket, where winter grit and brine collect off the car, and where broken strands and rust start. A cable with strands gone is on a countdown regardless of how the door looks.

Springs are checked for coil gaps, surface rust and pitting. The bottom brackets carry a warning label for a reason and are checked but not disturbed, since they sit under full cable tension. Beyond that: drum set screws, end bearing plates, track lag bolts, the top fixtures, section fatigue around the hinges, the state of the emergency release, and whether the weatherseal is still doing anything. Everything found is written up in plain language and split into what needs doing now and what can wait, which is useful if you are thinking about listing the house.
