After making a repair, how should you recheck the system?

Running the system under both automatic and manual control is the best approach to ensure a comprehensive check after making a repair. This method allows you to evaluate the full functionality of the system in different operating modes, which is essential for confirming that all components are working correctly and that the repair has resolved the issue effectively.

By testing in manual mode, you can isolate and control specific aspects of the system, identifying any potential problems that might not manifest in automatic mode. Conversely, running the system in automatic mode helps to confirm that the system’s built-in controls and settings are functioning as intended, ensuring reliability in normal operations. This dual approach ensures thorough verification of the repair, leading to a more confident assessment of the system's overall health.

Visual inspections and diagnostic tests are important; however, they might not provide as comprehensive a view of the system’s operational capabilities post-repair as running the system in multiple modes would.
