SOURCE1 2439716000 Pressure Switch -0.20 Inches Wc Pf

Product Description

The SOURCE1 2439716000 is a pressure switch designed for residential and light commercial gas furnaces. It monitors the negative pressure created by the inducer motor during the heating cycle. When pressure reaches the correct level, the switch signals the control board to allow ignition. If pressure is lost or outside the set range, the switch opens and shuts down the ignition sequence to protect the system. This safety function prevents the furnace from firing without proper airflow, which could cause incomplete combustion or carbon monoxide buildup. The pressure setting on this switch is -0.20 inches WC, and the configuration is PF. These values are factory-calibrated to match specific furnace models and must be an exact match for safe, reliable operation. Substituting a switch with a different pressure rating can cause nuisance lockouts or, more seriously, allow a furnace to run under unsafe conditions. HVAC technicians rely on OEM-matched pressure switches like this one to restore proper furnace function quickly and with confidence. This part is compatible with several popular York and Johnson Controls furnace models, including the TM9Y100C16MP11, TM9V100C20MP12C, and TM9Y080B12MP11. It is a direct replacement that fits the original mounting location and wiring harness without modification. Keeping an OEM-spec pressure switch on hand reduces diagnostic time and callback risk on heating service calls. This switch measures 16.55 inches in length, 13.55 inches in width, and 3.05 inches in height.
