Description
The International Comfort Products 1185810 is a genuine OEM Vent Pressure Switch designed to maintain safe and reliable operation in ICP heating systems. This critical safety component monitors the pressure differential within the venting system to confirm proper draft inducer operation before allowing the furnace ignition sequence to proceed.
How It Works
The vent pressure switch senses the negative pressure (vacuum) created by the draft inducer motor. If the inducer fails to establish adequate airflow — due to a blocked flue, failed motor, or restricted vent — the switch remains open, preventing ignition and protecting the heat exchanger and home from combustion byproducts.
