International Comfort Products 1193106 .50″ wc SPST Pressure Switch

Description

International Comfort Products 1193106 SPST Pressure Switch Overview

The International Comfort Products (ICP) 1193106 is an OEM replacement SPST (Single Pole, Single Throw) pressure switch calibrated at a set point of 0.50″ w.c. (inches water column). Designed for use in ICP-branded heating systems, this pressure switch monitors the negative pressure produced by the draft inducer to verify proper venting conditions before allowing the ignition sequence to proceed — a critical safety function in modern gas furnaces.

How It Works

The pressure switch senses the differential pressure created by the inducer blower during operation. When the inducer establishes adequate draft, the diaphragm inside the switch deflects and closes the SPST circuit, signaling the control board that it is safe to continue the ignition sequence. If sufficient draft is not detected — due to a blocked flue, failed inducer, or cracked diaphragm — the switch remains open, locking out the furnace and preventing unsafe operation.
