Icp 1192720 Pressure Switch 24V

Product Description

The INTERNATIONAL COMFORT PRODUCTS 1192720 is a genuine OEM pressure switch designed to monitor airflow conditions within gas furnace and air handler systems. It detects changes in pressure created by the inducer motor and signals the control board to proceed with or halt the ignition sequence accordingly. Operating at 24 volts, this switch is calibrated to a specific response threshold, which helps prevent nuisance trips and protects the system from operating under unsafe draft conditions. Licensed HVAC technicians install this part as a direct OEM replacement during routine service or diagnostic repair.

This pressure switch is used in residential heating systems where draft-proving is required before ignition can proceed. It is typically found on gas furnaces equipped with an inducer or draft blower assembly. When the inducer reaches proper speed and establishes adequate negative pressure, the switch closes and allows the control board to advance through the ignition sequence. A failed or out-of-calibration switch is a common cause of lockout faults and no-heat calls.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut off power to the furnace and close the gas supply valve before beginning any service work. Inspect the rubber hose connecting the switch to the inducer housing for cracks or blockages, as a compromised hose is a frequent cause of switch failure. Follow all applicable local codes and manufacturer service instructions when replacing this component.
