Understanding Garage Door Opener Wiring
A garage door opener typically uses a series of wires to connect various components, allowing the system to function properly. The 4 wire configuration is common in many models and includes a few essential components:
- Power Source: The electrical supply that powers the opener.
- Motor: The component that drives the garage door up and down.
- Limit Switches: Sensors that control how far the door opens and closes.
- Remote Control/Wall Switch: Devices that allow the user to operate the door from a distance or directly from the garage.
Components of a 4 Wire Garage Door Opener
To fully understand the wiring diagram, it’s important to recognize the components involved:
1. Power Wires: Typically, this includes two wires that provide AC power to the motor.
2. Motor Wires: Two additional wires that connect the motor to the control board.
3. Limit Switches: These are usually integrated into the motor mechanism and work to stop the garage door at the right position.
4. Control Circuit: Comprising wires that connect the wall switch and remote control to the motor.
