The SOURCE1 2427634001 is an OEM replacement pressure switch designed for use in York and compatible HVAC systems. This air pressure switch monitors changes in pressure within the system and sends a signal to control the unit's power accordingly. It helps keep the system running safely and within designed operating parameters. HVAC technicians rely on pressure switches like this one to protect equipment from running under improper conditions, such as a blocked flue or failed inducer motor. Without a functioning pressure switch, a furnace or air handler may run unsafely or fail to ignite at all. This part replaces the original SOURCE1 part number S1-02427634001 and is built to meet OEM specifications for reliable, consistent performance. It is rated at a pressure range of 0.65 IWC, meaning it activates or deactivates at 0.65 inches water column of pressure differential. This precise calibration ensures the switch works correctly with the equipment it is designed for. Compatible units include the P3URC14N09501E, P3URC20N09501E, and G9T10014UPC13C, among others. Using a genuine OEM replacement part like this one avoids the fitment and performance issues that can come with aftermarket alternatives. The switch is lightweight, weighing just 0.25 pounds, making it easy to handle during installation. HVAC professionals performing furnace repairs, seasonal maintenance, or system diagnostics will find this part straightforward to source and install. Keeping OEM-spec pressure switches on hand reduces downtime during service calls on York equipment.
The SOURCE1 2427634001 pressure switch delivers accurate pressure sensing and reliable system protection for York HVAC equipment. It is a direct OEM replacement that supports safe furnace operation and consistent climate control.
