Restore gas and power, then cycle the heater and verify that no over-temperature shutdowns occur under normal operation.
Maintenance Tip
Check heater high-limit switch function each season. If the heater frequently shuts off due to a high-limit trip or if you observe signs of switch failure (such as corrosion or physical damage), replace the limiters promptly. Using the OEM HAXTLK1930 kit helps maintain safe and reliable operation of your H-Series heater.
