Description
The York S1-024-25006-708 is an OEM replacement SPST (Single-Pole, Single-Throw) pressure switch engineered for York heating systems. Designed to monitor draft pressure within the venting and inducer circuit, this switch provides a critical safety function by verifying proper airflow before allowing ignition to proceed — protecting the heat exchanger and ensuring safe furnace operation.
Key Features
- OEM York replacement pressure switch for precise fit and reliable performance
- Set point: 1.20″ water column (“wc) — factory-calibrated for accurate draft sensing
- 1/4″ barbed port connection for secure, leak-free hose attachment
- SPST (Single-Pole, Single-Throw) switching action for straightforward open/close circuit control
- Monitors inducer motor operation and venting integrity before ignition
- Direct OEM replacement minimizes diagnostic guesswork and installation time
Application
This pressure switch is a direct OEM replacement for compatible York furnaces and air handlers. It is typically located in the inducer/draft circuit and opens or closes in response to the negative pressure generated by the draft inducer motor. If the correct pressure is not achieved — indicating a blocked flue, failed inducer, or disconnected hose — the switch prevents ignition, safeguarding the system and its occupants.
