Before you begin, it's important to take the necessary safety precautions. Disconnect the power to the garage door opener at the circuit breaker panel. This will prevent the opener from accidentally activating while you're working on it.

Wear gloves and safety glasses to protect yourself from any sharp edges or debris. If you're not comfortable working with electrical wiring, it's best to consult a qualified electrician for assistance.
