Reznor 43594 Flame Sensor 326010-701 such as incorrect RPM matchingThe Reznor 43594 Flame Sensor is a critical safety component designed for precise flame rectification in high performance heating equipment. As an authentic OEM Reznor part, it ensures the ignition module receives a consistent microamp signal (typically between 3 to 10 A), preventing the short cycling or lockout issues common with worn or carbon fouled sensors. Engineered to withstand the intense thermal stress of gas fired unit heaters, this sensor
