Description
The International Comfort Products 1179133 is a precision-engineered pressure switch designed as a direct OEM replacement for compatible ICP heating systems. Monitoring flue gas pressure to verify proper inducer operation, this switch is a critical safety component that helps protect your furnace from operating under unsafe draft conditions.
Key Features
- Set point: 0.80″ water column (“wc)
- Switch type: SPST (Single-Pole, Single-Throw)
- Connection: 1/4″ barb port for secure hose attachment
- OEM replacement part for International Comfort Products (ICP) furnaces
- Monitors inducer and draft pressure to ensure safe furnace operation
- Helps prevent furnace operation under improper venting conditions
How It Works
The pressure switch senses negative pressure created by the draft inducer motor during furnace operation. When the inducer establishes the correct airflow, the switch closes and allows the ignition sequence to proceed. If adequate pressure is not detected — indicating a blocked flue, failed inducer, or cracked hose — the switch remains open and locks out the furnace, protecting occupants from potential combustion hazards.
Application

- Suitable for residential gas furnace applications
