SOURCE1 2435903000 Dual Air Pressure Switch Assembly -0.8 5PF -0.45 Pf Replacement S1-02435903000

Product Description

The SOURCE1 2435903000 is a dual air pressure switch assembly designed for use in residential and light commercial HVAC systems. This switch monitors airflow and pressure conditions inside the unit to protect the system from unsafe operating conditions. When pressure falls outside the set range, the switch opens or closes its circuit to signal the control board and shut down or allow operation accordingly. This kind of protection is critical for preventing heat exchanger damage, inducer motor failures, and other costly breakdowns. The SOURCE1 2435903000 features a SPNO (Single Pole Normally Open) configuration, meaning the switch contacts remain open under normal resting conditions and close when the correct pressure threshold is reached. This dual switch assembly covers two pressure setpoints: -0.8 5PF and -0.45 PF, making it suitable for systems that require monitoring at multiple stages of the combustion air or venting process. HVAC technicians rely on dual pressure switches in high-efficiency furnaces and air handlers where both inducer performance and vent pressure must be verified before ignition is allowed. This part is a genuine OEM-grade replacement crafted to manufacturer specifications, ensuring a precise fit and reliable operation. It is compatible with popular York and Johnson Controls furnace models including D1NP060N09006TB, D1NP060N09006NX, and D1NP030N03646, among others. Having the correct pressure switch installed ensures the unit will start and run safely, cycle properly, and meet the original equipment performance standards. This assembly is the go-to choice for HVAC service technicians replacing failed or intermittently tripping pressure switches on York-branded equipment.
