Icp 1184656 High Pressure Switch Furnace

Product Description

The International Comfort Products 1184656 is a genuine OEM replacement high pressure switch designed for use in gas furnace systems. Pressure switches monitor the negative pressure generated by the inducer motor during the heating cycle, confirming proper draft before allowing the ignition sequence to proceed. This switch serves as a critical safety component that prevents the burners from firing if adequate venting pressure is not established. Licensed HVAC technicians handling furnace diagnostics, seasonal maintenance, or combustion safety inspections are the primary installers of this component.

This high pressure switch is suited for residential gas furnace applications where the original 1184656 switch has failed, drifted out of calibration, or been identified as faulty during a pressure switch circuit diagnostic. Using a genuine OEM replacement ensures the set-point and diaphragm sensitivity match factory specifications, which is important for maintaining proper ignition timing and combustion safety. Refer to the original equipment documentation to confirm this part applies to the specific furnace model being serviced.

Key Features

• Genuine OEM replacement part ensuring factory-matched pressure set-point
• Functions as a safety interlock in the furnace ignition control sequence

Compatibility

Designed as an OEM-style replacement high pressure switch for residential gas furnace systems where part number 1184656 is specified by the manufacturer.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect power to the furnace at the disconnect switch or breaker before removing or installing the pressure switch. The inducer assembly and attached tubing should be inspected for cracks, blockages, or moisture during the same service visit, as these conditions can cause repeated pressure switch failures. Verify correct hose barb connection and confirm the switch circuit closes properly during a draft test before returning the system to service.
