Source1 2434612000 Air Pressure Switch 1.20/0.40 Deac Replacement S1-02434612000

Product Description

The SOURCE1 2434612000 Air Pressure Switch is a direct OEM replacement component designed for York and Source1 furnace and air handler systems. This switch monitors pressure levels inside the HVAC system and signals the control board to turn the unit on or off based on those readings. It operates with a pressure range of 1.20 inches of water column on the closing side and 0.40 inches of water column on the deactivation side. This dual-threshold design helps protect the system from running under unsafe pressure conditions, such as a blocked flue, a failed inducer motor, or a clogged condensate drain. HVAC technicians and service professionals rely on air pressure switches like this one to maintain safe combustion and airflow operation in residential and light commercial furnaces. The switch is built to OEM specifications, ensuring a precise fit and reliable electrical connection without modification. Compatible units include the GM9S120D20DH11, GM9S060B12DH11, and PS9B12N060DH11, among others. When an air pressure switch fails, symptoms can include a furnace that will not ignite, a system that short cycles, or a unit that locks out on a fault code related to pressure sensing. Replacing a faulty switch with a verified OEM part helps restore normal operation quickly and reduces the chance of a callback. The 2434612000 is a compact and lightweight component, making it straightforward to handle and install during a service call. It is the correct choice for HVAC professionals who need a dependable, specification-matched replacement switch for supported York and Source1 furnace models.
