42001-0061S Air Flow Switch for MasterTemp & Max-E-Therm Pool Heaters | PentairThe genuine OEM Pentair Air Flow Switch (42001 0061S) is the safety sensor that confirms adequate combustion air is reaching the burner before allowing ignition. It monitors the pressure differential across the air metering orifice; once airflow reaches the required threshold, the switch closes the circuit to the hot surface igniter (HSI), which lights the gas air mixture. During a typical heating call, the blower and HSI energize simultaneously.
