Use wire nuts to secure the connections and wrap them with electrical tape for added safety.
Connecting the Safety Sensors
Safety sensors are a crucial component of any garage door repair system, ensuring that the door reverses if an obstruction is detected. Proper wiring and alignment are essential for their operation.
- Mount the Sensors: Install the safety sensors on each side of the garage door, typically 6 inches above the ground, using the provided brackets.
- Run the Sensor Wires: Use the 22-gauge bell wire to connect the sensors to the garage door opener unit. Route the wire along the door track and secure it with cable clips or staples, being careful not to damage the wire.
- Connect to the Opener Unit: Locate the sensor terminals on the back of the garage door opener unit. Connect the white wire to the white terminal and the black wire to the black terminal. Tighten the screws to secure the wires in place.
- Align the Sensors: Ensure the sensors are properly aligned and facing each other. The indicator lights on the sensors should be steady, indicating proper alignment. If the lights are blinking, adjust the sensors until they are correctly aligned.
Wiring the Wall Control Panel
The wall control panel allows you to operate the garage door opener from inside the garage. It also provides additional functions such as turning on the opener light or locking the door.
- Mount the Control Panel: Install the wall control panel on the wall inside the garage, near the entrance to the home, at a height that is easily accessible.
- Run the Control Wire: Use the 22-gauge bell wire to connect the wall control panel to the opener unit. Route the wire along the garage wall and ceiling, securing it with cable clips or staples.
- Connect to the Opener Unit: Locate the control panel terminals on the back of the garage door opener unit. Connect the wires according to the manufacturer’s instructions, typically red to red and white to white. Tighten the screws to secure the wires.
Testing the Wiring Connections
After wiring the power supply, safety sensors, and wall control panel, it’s time to test the connections to ensure everything is working correctly.
- Restore Power: Turn the power back on at the circuit breaker and plug in the garage door opener.
