Modern openers have two safety systems that are supposed to stop the door from crushing anything in its path. Both can fail silently. Here’s how to test them in under a minute.
The photo-eye test
With the door open, start it closing and wave a broom through the beam near the floor. The door should immediately reverse. If it doesn’t, the photo eyes may be misaligned or failing.
The reversal (force) test
Lay a roll of paper towels flat in the door’s path and close it. When the door touches the roll it should reverse. If it keeps pushing, the down-force is set too high.
If either test fails
Stop using the opener for anything but supervised operation and call us. We’ll realign the sensors and recalibrate the force the same day. It’s a quick, important fix.
