During PDI on RV furnaces, to what setting should the thermostat be set?

Setting the thermostat to the highest setting during the Pre-Delivery Inspection (PDI) on RV furnaces is essential for several reasons. First, this setting ensures that the furnace is tested under maximum load conditions. By doing so, technicians can evaluate the furnace's performance comprehensively, checking if it reaches the desired temperatures quickly and efficiently.

This approach also helps identify any potential issues with the heating components or airflow that may not be apparent at lower settings. A thorough test at high settings enhances the likelihood of uncovering any defects or malfunctions before the RV goes to the customer, ensuring that it operates safely and effectively.

Understanding this operational context is crucial for anyone dealing with RV furnaces and their performance testing. It emphasizes the importance of rigorous quality checks in the RV industry, leading to improved user satisfaction and safety.
