Swimables SW‑41‑061 air flow switch designed for Pentair MasterTemp and Sta‑Rite Max‑E‑Therm heaters. Ensures proper blower airflow for safe ignition, supports stable flame start-up, and includes clip, tubing, and hardware for straightforward installation.

Key Features:

  • OEM-equivalent replacement: Direct alternative to Pentair part #42001‑0061S, compatible with MasterTemp and Max‑E‑Therm pool heaters 

  • Airflow detection: Senses pressure drop across the air metering orifice to verify sufficient blower airflow before ignition 

  • Ignition circuit activation: Closes the hot surface igniter (HSI) circuit upon confirmed airflow, enabling safe and reliable ignition sequence 

  • Rapid heat call response: Coordinates blower and ignition activation, leading to gas valve opening within ~20 seconds 

  • Complete hardware kit: Includes switch, mounting clip, two clear tubing pieces, and mounting bolts for a plug-and-play replacement 

Product Overview:
The Swimables SW‑41‑061 Air Flow Switch serves as a pivotal safety device within the ignition system of Pentair MasterTemp and Sta‑Rite Max‑E‑Therm pool heaters. When a heat call is initiated, the heater’s blower motor and hot surface igniter (HSI) are both energized. The air flow switch monitors the pressure differential across the air metering orifice; once sufficient airflow is detected, it closes the ignition circuit, allowing fuel ignition. If airflow is inadequate, the circuit remains open, preventing unsafe ignition conditions. 

Engineered to meet OEM specifications under part #42001‑0061S, the SW‑41‑061 includes everything required for replacement: the switch itself, clear tubing, mounting clip, and bolts. This ensures ease of installation when replacing a worn or faulty switch. Especially crucial after blower maintenance or replacement, installing this component ensures the heater resumes safe and efficient starting operations.

Ideal for pool service technicians and homeowners performing maintenance or repairing ignition failures, the SW‑41‑061 restores heater safety and reliability, helping prevent incomplete ignition and potential heater faults. Keep this switch on hand to maintain uninterrupted, confident operation of your pool heater lineup.
