Garage Door Opener Repair: Upon receiving a service request from a customer regarding their malfunctioning garage door opener, I conducted a prompt and detailed inspection. During the initial assessment, I pinpointed a worn sprocket as the culprit behind the opener's issues, manifesting in a humming noise and unreliable performance. To address this, I promptly replaced the damaged sprocket. Additionally, I conducted a comprehensive examination of the entire garage door opener system, ensuring that all components were in optimal condition. Rigorous testing followed to guarantee not only the elimination of the humming noise but also the quiet and efficient operation of the garage door opener.
