Source1 2439479000 Pressure Switch with Bracket 0.28 Water Column S1-02439479000

Product Description

The SOURCE1 2439479000 is an OEM pressure switch with bracket designed for use in York and compatible HVAC systems. This pressure switch monitors changes in system pressure and signals the unit to turn on or off as needed, helping maintain safe and efficient operation throughout the heating and cooling cycle. Pressure switches are a critical safety component in gas furnaces and air handlers. They detect whether the inducer motor is creating the correct draft before allowing the ignition sequence to proceed. A failed or faulty pressure switch is one of the most common causes of furnace lockout and no-heat calls, making this a high-demand replacement part for HVAC technicians and service professionals. The SOURCE1 2439479000 is rated at 0.28 water column, which corresponds to the specific differential pressure threshold required by compatible equipment. Using a correctly rated switch is essential. Installing a switch with the wrong pressure rating can cause nuisance lockouts or, more seriously, allow ignition under unsafe draft conditions. This part includes the mounting bracket, so it installs as a complete assembly without the need for sourcing additional hardware. It is manufactured to OEM specifications, meaning it is built to the same standards as the original part it replaces. Compatible units include popular York models such as the 1LD0404, 1HA0443, and 1HA0451, among others. HVAC technicians replacing a draft pressure switch, furnace pressure switch, or inducer pressure switch on York equipment will find this part a direct and reliable fit. The compact dimensions make installation straightforward even in tight equipment cabinets.
