Here’s the step-by-step process to connect the wires safely and correctly.
Step 1: Turn Off Power
Always start by cutting power to the garage door opener at the circuit breaker. This is essential for your safety.
Step 2: Connect the Wall Control Panel
Your wall control panel (or push button) will need two wires: one to the red terminal and one to the white terminal.
- Use a wire stripper to expose about ½ inch of the wire on both ends.
- Connect one wire to the white terminal (common).
- Connect the other wire to the red terminal.
- Secure the wires with a screwdriver, making sure they’re firmly in place.
Step 3: Install the Safety Sensors
The safety reversing sensors are typically placed on each side of the garage door, 4–6 inches from the ground.
- Connect the black wire from each sensor to the black terminal on the opener.
- Connect the white wire from each sensor to the white terminal.
This creates a complete circuit and ensures that the sensors can “see” each other. If the beam is interrupted, the door will stop closing—a crucial safety feature.
Step 4: Secure All Wiring
Use staples or clips to secure the wiring neatly along the ceiling and walls. Avoid pinching or damaging the wires during this step.
Step 5: Restore Power and Test
Flip the circuit breaker back on. Test the wall panel, safety sensors, and remote control to make sure everything works.
Common Wiring Mistakes and How to Avoid Them
Even seasoned DIYers can make errors. Here are some common mistakes and how to avoid them:
- Reversing terminals: Always check the manual to ensure wires are connected to the correct terminals.
- Poor contact: Make sure all stripped wire ends are making firm contact inside the terminal screws.
- Wrong wire gauge: Use 18–22 AWG insulated wire for best results.
- Ignoring polarity: While some low-voltage wiring isn’t polarized, sensor wires typically are—match wire colors appropriately.
