SKU: 462023Z
Pentair Flame Sensor for ETi 250, ETi 400 & UltraTemp ETi Heaters | 462023Z
Pentair 462023Z Flame Sensor is a genuine OEM replacement component designed for select Pentair ETi 250, ETi 400, and UltraTemp ETi hybrid pool and spa heaters. This flame sensor plays an essential role in the heater's ignition safety system by detecting the presence of a burner flame during operation.
A properly functioning flame sensor allows the heater's ignition control system to verify that combustion has been established. If the flame cannot be detected, the control system can shut down the gas supply to help prevent unsafe operating conditions. Replacing a worn, damaged, or malfunctioning flame sensor can help restore reliable heater performance when the sensor has been identified as the cause of an ignition problem.
