Heil Quaker ICP 1184424 Limit Switch
The Heil Quaker ICP 1184424 Limit Switch is a critical safety component engineered to monitor and regulate the internal temperature of high-efficiency furnaces. Specifically calibrated with an L160-20F specification, this switch manages fan cycles and acts as a primary fail-safe, interrupting power to the gas valve if the supply plenum exceeds the 160?F cut-out threshold. Manufactured by International Comfort Products, this genuine OEM replacement part ensures the tight tolerances required for residential and light commercial heating systems. Using an original ICP 1184424 is vital for maintaining the integrity of the heat exchanger and preventing thermal damage often caused by restricted airflow or blower motor fatigue. Its precise 20?F differential provides a stable reset point, ensuring your equipment returns to operation only when safe thermal conditions are restored.
Key Benefits:
- OEM Precision Calibration: Features a factory-set 160?F cut-out and 20?F differential for exact furnace high limit switch performance.
- Broad System Compatibility: Designed for an integrated fit within Heil, Tempstar, Comfortmaker, and Arcoaire systems, including popular models like the G96CTN and G95CSU.
- Enhanced System Safety: Protects against overheating by directly monitoring the heat exchanger temperature and controlling fan logic.
- Industrial-Grade Construction: Built to withstand the high-cycle demands of modern HVAC air handlers and furnaces.
- Direct Technical Replacement: Replaces L160-20F series switches without the need for mounting modifications or bracket adjustments.
Common Questions:
What causes this limit switch to trip frequently?
Repeated tripping is usually a symptom of restricted airflow. Check for a clogged furnace filter, blocked supply registers, or a failing blower motor. If the airflow is confirmed to be within manufacturer specs, the switch itself may have developed "nuisance tripping" due to thermal fatigue and requires replacement.
Can I use a higher temperature limit switch as a substitute?
No. The 1184424 limit switch is safety-rated specifically for the heat exchanger it protects. Installing a switch with a higher cut-out temperature can lead to cracked heat exchangers or dangerous operating conditions. Always match the L160-20F code to the original equipment specifications.
How do I confirm if my switch is faulty?
A veteran technician will check for continuity across the terminals when the system is cool. If the circuit is open at room temperature, the switch has failed. If the system shuts down but the plenum is not physically overheating, the internal bimetal disc may be out of calibration.
