Description
The Amana / Goodman 20197312 is a genuine OEM air pressure (vacuum) switch, calibrated to –0.37″ water column (WC). This switch is used in many Goodman, Amana, and Janitrol furnaces to monitor airflow and proper inducer operation. When installed, it ensures safe furnace combustion by verifying that the inducer fan is creating adequate vacuum before permitting ignition.
Features:
- Factory‑Original Quality: This is a genuine Amana / Goodman part, not an aftermarket equivalent, providing reliable performance and compatibility with original system designs.
- Precise –0.37″ WC Calibration: The switch is preset to trip at –0.37″ W.C., making it effective for systems that require moderate vacuum levels for safe operation.
- Light‑Blue Indicator Housing: The characteristic light-blue color makes it easy to identify in HVAC assemblies.
- Wide Application & Compatibility: Works across many furnace models in the Goodman, Amana, and Janitrol lines. It replaces older pressure switch part numbers such as 20197305.
- Robust & Durable Construction: Built to stand up to the rigors of HVAC operation, including pressure cycling, vibration, and temperature changes.
