The K16RA-36 thermocouple is engineered for high-ambient temperatures

Replacing a faulty P59900 pressure switch with OEM HVAC controls eliminates the guesswork of universal "will-it-fit" parts and ensures the unit operates within manufacturer parameters

Key Benefits Precise Switchover Control: Maintains consistent performance within the 11 to 15 psig range for accurate pneumatic air switching

replacing an 825 RPM motor with a higher speed motor will lead to improper head pressure and potential compressor failure

making it a reliable OEM replacement part for critical combustion environments

Lochinvar & A.O. Smith 100112678 Flame Sensor 323613-751 The K16RA-36 thermocouple is engineeredThe Lochinvar & A. O. Smith 100112678 Flame Sensor is a critical OEM safety component engineered for precise flame rectification in high efficiency boilers and water heaters. Designed for Lochinvar Knight and A. O. Smith B4940, B5930, B5940, and B7930 series units, this sensor monitors the burner's ionized path to ensure the gas valve remains energized only when a stable flame is present. Constructed with a high grade Kanthal or equivalent alloy rod
