International Comfort Products 1192373 Pressure Switch

Product Description

The INTERNATIONAL COMFORT PRODUCTS 1192373 is a furnace pressure switch designed to monitor air pressure within the venting and combustion system of residential gas furnaces. It verifies that the inducer motor assembly is generating adequate draft before permitting the heating cycle to advance. If airflow or venting conditions fall outside acceptable limits, the switch signals the control board to halt operation, protecting both equipment and occupants. Licensed HVAC technicians install this component as part of routine furnace service or safety-system repair. It is a direct-acting safety device critical to proper furnace sequence of operation.

This pressure switch is intended for use in residential gas furnace applications where draft-proving is required as part of the ignition sequence. It monitors the negative pressure produced by the inducer blower and communicates status to the integrated furnace control board. Typical installation scenarios include replacement of a failed or out-of-spec pressure switch during a no-heat service call or as part of a venting system repair. Compatible furnace applications are limited to those specified by INTERNATIONAL COMFORT PRODUCTS for part number 1192373.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with applicable local codes and the furnace manufacturer service instructions. Shut off power to the furnace at the disconnect or breaker and allow the inducer assembly to come to a complete stop before removing or installing the pressure switch. Inspect the rubber pressure port tubing for cracks, blockages, or improper routing, as tubing condition directly affects switch performance. Do not bypass or jumper the pressure switch under any circumstances.
