Description
Safeguard your heating system with the Pentair 472251 Flame Sensor, a genuine OEM safety component engineered for Pentair MiniMax NT TSI pool and spa heaters. This sensor continuously monitors the burner flame and communicates its status to the control board, which then determines whether to sustain gas flow or shut it off to prevent hazardous conditions. When a flame sensor deteriorates or fails, the heater may refuse to light or may abruptly shut down mid-cycle as a protective measure. Constructed from heat-tolerant materials that withstand the intense thermal environment inside the combustion chamber, the 472251 provides dependable flame detection over an extended service life. Purpose-matched to MiniMax NT TSI models, it delivers the exact fit and signal characteristics your heater requires. The replacement process is uncomplicated, allowing pool owners and service technicians to quickly swap the sensor and restore full heating capability.
