Upon arrival, I conducted a thorough inspection of the defrost control panel. During the examination, I identified an issue with stray voltage emanating from the control panel. This stray voltage posed a potential safety hazard and could lead to inefficiencies in the system's operation. I meticulously traced the source of the voltage, ensuring all connections were secure and properly insulated. After resolving the issue, I performed a series of tests to confirm that the stray voltage had been eliminated and that the system was operating within safe parameters. The defrost control panel is now functioning correctly, ensuring optimal performance and safety.
