Description
Replaces the air flow switch on MasterTemp and Max-E-Therm heaters – Sta-Rite 42001-0061S. It proves blower airflow before ignition so the heater only fires when there’s proper combustion air. This OEM switch fits SR-200, SR-333, SR-400 and MasterTemp 200/300/400 models, and supersedes part 42001-0059S.
Includes: Air flow switch
