Which of the following is considered a major repair of an appliance?

The overhaul of a hydraulic pressure pump is considered a major repair of an appliance because it involves significant disassembly and reassembly of the pump components. This type of repair typically requires a high level of technical skill and specialized knowledge, as it often addresses the core functionality of the hydraulic system. Overhauling indicates that the pump will be thoroughly inspected, cleaned, and any worn or damaged parts will be replaced, which restores its optimal performance.

This process is usually time-intensive and may require testing after the overhaul to ensure everything operates correctly, further distinguishing it from simpler repairs or maintenance tasks. In the context of appliance management within the GACA framework, such major repairs are critical to maintaining safety and performance standards, making them substantially different from minor repairs or routine maintenance activities.
