Replaced a faulty thermal regulator on a pool heater that was causing inconsistent water temperatures. After shutting off the system, I removed the old regulator, which was corroded and not functioning correctly. Installed a new OEM thermal regulator, ensuring it was properly aligned and secured. After reassembly, I tested the system to confirm that the water temperature was stable and consistent. The replacement resolved the issue, and the pool heater is now operating efficiently.
