Description
The International Comfort Products IS203655708 is an OEM replacement pressure switch engineered for precise draft and combustion airflow monitoring in ICP heating systems. With a calibrated setpoint of 0.65″ water column (w.c.), this switch reliably detects proper inducer operation and prevents furnace ignition under unsafe pressure conditions — protecting both equipment and occupants.
Key Features
- Calibrated setpoint of 0.65″ w.c. for accurate pressure sensing
- SPST (Single-Pole, Single-Throw) switching action for straightforward circuit control
- 1/4″ barb connection for secure, leak-free tubing attachment
- OEM-quality construction for direct replacement in compatible ICP systems
- Monitors inducer/draft pressure to ensure safe furnace operation
- Helps prevent nuisance lockouts while protecting against unsafe conditions
Application
This pressure switch is designed as a direct OEM replacement for International Comfort Products furnaces and air handlers. It monitors the negative pressure generated by the draft inducer motor to confirm adequate airflow before allowing ignition. If pressure falls outside the specified range, the switch opens the control circuit, shutting down the ignition sequence to prevent unsafe operation.

Why Choose an OEM Replacement?
Using a factory-matched pressure switch ensures the correct setpoint calibration for your specific ICP equipment model. An improperly rated switch can cause nuisance shutdowns or, worse, allow the system to operate under unsafe draft conditions. The IS203655708 delivers the exact performance specification your system was designed around.
