Description
The Amana‑Goodman B1370209 is a factory OEM 2‑stage air pressure (vacuum) switch used in many Goodman, Amana, and Janitrol furnace systems. It helps ensure safe and proper furnace combustion by verifying inducer fan vacuum levels before allowing ignition.
Features:
- Genuine OEM Component: Designed by Amana/Goodman to meet rigorous standards — delivers reliability and proper fitment over aftermarket alternatives.
- 2‑Stage Switch Functionality: Unlike a single‑stage pressure switch, this 2‑stage model offers more nuanced control over pressure thresholds, giving your system better accuracy in detecting vacuum levels.
- Preset Vacuum Range (~0.30 to 0.50 in WC): The B1370209 is often rated around –0.30 to –0.50 inches of water column (WC) for its operating range, ensuring compatibility with many furnace duct and inducer designs.
- Robust and Durable Construction: Built to withstand the temperature, vibration, and pressure cycling typical in furnace environments. OEM design minimizes drift or failure over time.
- Drop‑in Replacement: Swap it in with matching vacuum tubing and wiring — most installs don’t require bracket modifications or calibration adjustments. HVAC technicians appreciate its plug‑and‑play nature.
