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.
