Source1 2435929000 Air Pressure Switch 0.15 Inches Wc on Fall Spno

Product Description

The Source1 2435929000 is an OEM air pressure switch designed for use in York and compatible HVAC systems. It monitors air pressure within the system and responds to changes in that pressure to protect equipment and maintain safe operation. This switch is rated for an activation pressure of 0.15 inches WC on fall, meaning it trips when pressure drops to that threshold. It is configured as SPNO, or Single Pole Normally Open, which means the circuit is open under normal conditions and closes when the switch is activated by a pressure change. HVAC technicians rely on pressure switches like this one to verify that inducer motors are operating correctly before allowing ignition to proceed. If the switch does not detect the proper pressure, it prevents the furnace or air handler from firing, protecting the heat exchanger and other components from damage. This is a critical safety and control component in forced-air heating systems. The Source1 2435929000 is a direct OEM replacement part, engineered to integrate seamlessly with York equipment. Using a genuine OEM switch ensures correct calibration, proper electrical compatibility, and reliable long-term performance. The switch measures 5.7 inches in length, 3.1 inches in width, and 2.95 inches in height, making it a compact component that fits within standard equipment enclosures. It weighs just 0.17 pounds, which is typical for this style of pressure switch. HVAC service professionals, contractors, and technicians looking for a dependable York-compatible pressure switch replacement will find this part meets OEM specifications without modification.

• Activation pressure of 0.15 inches WC on fall for precise pressure-based control
