Heil Quaker ICP 1171901 Limit Switch
The Heil Quaker ICP 1171901 Limit Switch is a critical safety component engineered for precision temperature monitoring within the furnace plenum. As an OEM L150-55 AUTO Limit Switch, this part is calibrated to open the electrical circuit when internal temperatures hit 150?F, effectively shutting down the burners while keeping the blower motor engaged to cool the heat exchanger. This furnace high limit control is built for high-duty cycles and provides the accurate actuation needed to prevent thermal stress and potential cracks in the HVAC heat exchanger.
Designed for compatibility with a wide range of International Comfort Products equipment including brands like Tempstar, Comfortmaker, and Heil, the 1171901 serves as a direct OEM HVAC replacement part. It effectively manages furnace short cycling issues caused by restricted airflow or failing thermal sensors. By maintaining tight tolerances for both the 150?F trip point and the 55?F reset differential, this disc-style limit switch ensures your service calls result in long-term system reliability and code-compliant operation.
Key Benefits for the Contractor:- OEM Precision: Genuine ICP Replacement Part ensures exact fitment and factory-spec thermal response without the calibration drift common in universal alternatives.
- Automatic Reset: The L150-55 AUTO functionality eliminates unnecessary manual resets, allowing the system to restore furnace ignition sequence once safe temperatures are reached.
- System Protection: Actively prevents HVAC overheating and damage to sensitive electronic components by regulating furnace temperature rise.
- Broad Compatibility: Fits popular residential units including EHC15AKF3 and EHK07AKB1, providing a versatile solution for ICP furnace repair.
Why is my furnace blower running constantly while the air stays cool?
When a limit switch trips due to overheating or mechanical failure, the control board initiates a safety cool-down mode. If the 1171901 switch remains open or is stuck, the blower fan will continue to run to protect the system from heat damage.
Can I use a universal switch instead of the 1171901?
While universal parts exist, they often lack the precise L150-55 temperature rating required for specific Heil Quaker systems. Using the OEM 1171901 ensures that the safety limits align perfectly with the original manufacturer?s thermal design.
How do I know if the limit switch has failed or if it?s an airflow issue?
Check for continuity across the terminals. If the switch is open at room temperature, it is faulty. If it only trips during operation, inspect for clogged air filters or obstructed ductwork causing high static pressure.
