DOOR DOES NOT CLOSE or REVERSES DURING TRAVEL

Garage door openers are now required to have electronic reversing systems at the base of the door. It is best known as garage door safety sensors. Serious injuries and deaths have occurred due to garage doors crushing down instead of automatically going back up when someone or something is detected in its path. National standards were estabished in 1992 to prevent these types of accidents.

The infrared safety sensors are essential in garage safety. Typically mounted 4-6 inches from the ground along the both sides of the garage door track, the sensors detect any obstacles between the garage door and the ground, and reverse or force the garage door to stay open to prevent injury to anyone or pets and damage to property.

Common Problems of malfunctioning safety sensors:

  • An obstruction in the way of the sensors. Even dust, dirt, cobwebs and leaves can block the sensors’ beams.

  • Sensors are misaligned (the beams do not “see” each other)

  • Sometimes sun light shining on the sending sensor may send signals that an obstruction is in the way

  • Problem with connection or with wiring

  • defective or damaged lenses

​​Most garage door sensors have a light that is programmed to blink to indicate a problem. If your garage door does not close or reverses during travel along with blinking light on your motor head, check to make sure that your sensors are clean and an obstruction is not keeping your garage door from closing. If your door still does not close, give us a call for trouble shooting or replacement of your defective or damaged sensors. Properly functioning garage door safety sensors help make sure your garage remains safe.

If your garage door goes down but then opens again, the board inside the motor may be becoming weak or the limit switch may need to be adjusted. The limit set on your limit switch tells the garage door opener how far the door should move before it is fully open or closed. If you need help diagnosing this problem or to reset the limit switch, give us a call.​
