York S1-024-27632-001 Pressure Switch

The York S1-024-27632-001 Pressure Switch is a critical safety component designed for specific HVAC pressure monitoring applications. This factory-authorized part is engineered with a setpoint of 0.4" WC (Water Column) and utilizes a Single Pole Normally Open (SPNO) internal contact configuration. Unlike standard switches, this unit is built to close on a fall in pressure, ensuring precise control and system protection during negative pressure changes. This mechanical switch is a direct replacement for various York and Coleman equipment, specifically compatible with model DGAD060CDD.

As a veteran tech, you know that maintaining the correct induced draft is non-negotiable for safe ignition. The S1-024-27632-001 features a durable diaphragm and 2-wire electrical connection for reliable furnace operation under demanding conditions. When troubleshooting, verify the manometer readings against the 0.4" WC spec to ensure the combustion air pressure switch is reacting correctly to the inducer motor’s vacuum. Integrated into the safety circuit, this 0.4-inch WC pressure control prevents the system from firing if venting is compromised or a blocked exhaust vent is detected, safeguarding the heat exchanger and occupants.

• Factory-Calibrated Precision: Set to 0.4" WC to ensure exact pressure switch setpoint accuracy for OEM performance.
• Application Compatibility: Primarily used as a close-on-fall switch for draft induction and safety lockout circuits.
• Industrial Durability: Robust casing and high-quality diaphragm designed to withstand high-cycle furnace startup sequences.
• Simplified Integration: Direct fit for York S1-024-27632-001, featuring standard push-on terminals for quick field replacement.

• How do I test a York S1-024-27632-001? Use a multimeter to check for continuity across the terminals. Since this is an SPNO close on fall switch, the circuit should close once the inducer motor creates a vacuum exceeding the 0.4" WC threshold.
• What causes this switch to stay open? Most issues stem from a cracked pressure switch hose, moisture buildup in the tubing, or a failing inducer motor that cannot pull the required vacuum.
• Can I use this switch for any 0.4" WC application? No. This specific model is a close on fall switch. If your system requires a switch that opens on a pressure drop, this will not function correctly for your sequence of operation.
