Digital reset of electronic opener closing limits so the door seals without triggering safety reverses.
Precision adjustment of internal motor pressure safety triggers to offset weather drag.
Comprehensive testing with physical blocks to guarantee absolute crush prevention safeguards.
Identify your garage door issues early to avoid costly secondary damage.
Safety photo-eyes are out of alignment or blocked. The opener clicks, flashes its bulbs 10 times, and refuses to close to prevent crushing hazards.
Travel limits are miscalibrated. The opener motor interprets the floor as an obstruction and triggers an automatic safety reversal to prevent panel warping.
The vertical track channels are bent or out of plumb at the bottom, binding the roller bearings and triggering the motor force safety reverse.

This is most commonly triggered by the safety photo-eye sensors. If a sensor light is blinking or dark, the system thinks there's an obstruction (like a child or pet) and reverses. Clear any spiderwebs, dirt, or adjust the sensors until both lights shine steadily.
In an emergency, you can close the door by pressing and holding the wall button console down continuously until the door is completely closed. Note that remotes will not work in this state, and this override is only a temporary safety bypass.
If the door closes completely, hits the floor, and immediately reverses, your "Down Limit" is set too far down. The opener is trying to force the door further than the floor allows, misinterpreting the ground as an obstruction.
