Heil Quaker ICP 1171484 Limit Switch
The Heil Quaker ICP 1171484 Limit Switch is a critical high-limit safety component engineered for International Comfort Products (ICP) furnace and packaged units. As a veteran-grade HVAC replacement part, this switch features a calibrated 225-50 degree temperature range, specifically designed to monitor heat exchanger temperatures and prevent thermal overstress. When the internal plenum temperature exceeds the 225°F threshold, the circuit opens to terminate the heating cycle, automatically resetting once the system cools to 50°F. This OEM furnace limit switch is a direct-fit solution for PDS4 units and various Heil Quaker furnaces, ensuring the electrical footprint and mounting geometry align perfectly with the original factory specifications. By utilizing a genuine 1171484, technicians maintain the integrity of the unit's safety string while avoiding the calibration drift often associated with generic aftermarket alternatives. This component is essential for any HVAC repair involving rapid cycling or high-limit trip errors in ICP-branded equipment.
Technical Benefits for Contractors:- OEM Precision: Engineered by ICP to meet exact thermal switch specifications for Heil, Quaker, and Tempstar equipment.
- Critical Safety Logic: Features a fixed 225°F cutout and 50°F differential to protect the heat exchanger from structural failure.
- Optimized Compatibility: Verified 1171484 limit switch design for seamless integration into PDS4 series air handlers and gas furnaces.
- Rugged Build Quality: Built to withstand the high-static environments of commercial and residential blowers without premature fatigue.
What causes a 1171484 limit switch to trip frequently?
Usually, a trip indicates restricted airflow. Check for a clogged furnace filter, blocked return ducts, or a failing blower motor before replacing the sensor.
Is this switch compatible with other ICP brands?
Yes, this is a universal ICP replacement part compatible with Comfortmaker, Arcoaire, and Day & Night units that call for the 1171484 part number.
Can I test this switch with a multimeter?
Yes. At room temperature, this limit switch should show continuity (0 ohms). If the circuit is open when the unit is cool, the switch has failed and requires replacement.
