It is important to wire the garage door sensors safely and perfectly. The door can reverse automatically if there is a problem with the wires, which is dangerous.
So, how to wire garage door sensors?
Wiring garage door sensors
Quick Connect Plug-In Terminals
Two wires run through each sensor, one white with a black stripe and one white with a solid white wire. Remove 7/16 inches of insulation from each sensor’s two wires.
Connect both white-with-black-stripe wires of the sensors.
Then, You will need to twist together the two white, solid wires that come from both sensors.
To the white terminal of the motor unit, connect the two solid white wires as well as the gray terminal.
Using pre-existing wires to connect quick-connect terminals
The insulation on both white-with-black-stripe wires should be removed by seven-sixteenths of an inch.
Every white wire with a black stripe and solid white wire with a black stripe should be stripped of 7/16 inches of insulation.
By splicing a colored wire into the solid-white wire, connect it to the motor unit’s white terminal below its grey terminal.
Openers with Screw Terminals
Both solid-white and white-with-black-stripe wires must be insulated 7/16 inches.
Then, Both white wires from the sensors should be twisted together.
Connect both solid-white sensors together by twisting them together.
Attach the two white-with-black-stripe wires to the motor unit’s screw terminal 3.
Connect the two solid-white wires to the screw terminal 2 of the motor unit.
Screw Terminals Using Pre-Existing Wires
In both sensors, remove 7/16 inches of insulation from the white wires with black stripes and the solid white wires.
To connect to motor unit screw terminal 3, splice whatever color wire you want to the white-with-black-stripe wire.
Splice any color wire to the solid-white wire and connect it to terminal 2 of the motor unit.
Use electrical tape or wire caps to protect each wire splice.
