Source1 2439706000 Air Pressure Switch 0.10 Inches Wc Replacement S1-02439706000

Product Description

The SOURCE1 2439706000 is an OEM air pressure switch designed for use in residential and light commercial HVAC systems. This component monitors air pressure within the system and triggers on/off responses to keep the unit operating safely and correctly. When airflow conditions change, the pressure switch signals the control board to allow or stop operation, helping prevent damage from blocked flues, failed inducer motors, or unsafe combustion conditions. This makes the pressure switch a critical safety and performance component in any forced-air heating or cooling system.

This switch is rated at 0.10 inches WC, meaning it responds to very low differential pressure levels, which is typical for draft-inducer pressure sensing in gas furnaces and air handlers. HVAC technicians rely on pressure switches like this one to diagnose and correct operational faults, error codes, and lockout conditions. When a furnace fails to light or shuts down mid-cycle, a faulty pressure switch is one of the first components checked. Replacing it with a direct OEM part ensures the system returns to factory-specified performance without compatibility guesswork.

This part is a direct replacement for the SOURCE1 part number S1-02439706000 and fits a range of York and compatible units including AC5B060F1C, AC6B042F3C, and AC5B060F3C among others. Using genuine OEM replacement parts helps maintain the original equipment warranty and ensures the switch meets the exact electrical and pressure specifications required by the system. The compact housing measures 2.4 inches in length, 2.35 inches in width, and 1.5 inches in height, making it a straightforward drop-in replacement for qualified technicians.
