When
garage doors go up but they don’t come back down again, there is usually a
reason. Today, I am going to share with you the five things to consider looking
at when this issue happens with your garage door.
Major Safety
Sensors Not Lining Up
On
most garage doors there are safety sensors designed to detect any obstruction
between each on both sides of the garage door and automatically prevent the
door from closing. When there is something in between each of these sensors, or
if there is a problem with the way they are operating, your door may not close.
Check to see if the red light is solid or whether it is a flashing light.
Flashing lights indicate the sensors on either side do not line up.
LIftmaster Safety
Sensors Misaligned
The
second type of safety sensor that is in place with most garage doors is a
LIftmaster sensor. Similar to the major safety sensors, they need to line up.
When you examine each of these units, make sure the green light is lit
properly.
Faulty Wiring in
Sensors
A
common concern that arises in safety sensors is wiring that has lost its
integrity or connection over time. This can happen during installation if a
staple might have pierced the wire partially, or if the connection points have
suffered corrosion and need to be cleaned, serviced and redone.
Motor Head Wiring
Overstretched
After
time, the wires on your garage door opener’s motor head can become stretched
out and even removed from terminals. Depending on the style of garage door
opener you have, you will need to remove the cover to check the wire
connections. If something is loose or corroded, you will need to call for
service.
Garage Door Sensor
Brackets Not Mounted Correctly
Sometimes
garage door brackets are mounted on wood while other times they are mounted
directly onto steel. Depending on they type of door you have, you will either
see brackets mounted to wood or snapped and fit onto the steel rail. If the
sensors are not mounted correctly you can experience issues with garage door
operation.
