Heil Quaker ICP 1183523 Limit Switch
Professional-grade furnace maintenance requires exact thermal calibration, and the Heil Quaker ICP 1183523 Limit Switch is the genuine OEM replacement part engineered for high-limit protection in International Comfort Products systems. This 190-degree F furnace limit switch serves as a critical safety component, monitoring the supply plenum temperature to prevent heat exchanger damage. Featuring a normally closed circuit, this bimetal disc limit switch is designed to open on a temperature rise at 190°F and includes an automatic reset function that closes the circuit once the temperature drops to 150°F. This HVAC high limit sensor is compatible with a wide range of brands under the ICP umbrella, including Tempstar, Comfortmaker, Heil, and Arcoaire. Its robust construction ensures long-term reliability in high-demand residential heating applications, specifically fitting popular furnace models like the F8MXL and N80ESN series. Replacing a tripped or faulty switch with this OEM 1183523 part is essential for preventing short-cycling and ensuring consistent blower motor operation.
Key Benefits for Technicians:
- Precision Thermal Calibration: Fixed 190°F trip point ensures the burner shuts down before the heat exchanger reaches critical failure temperatures.
- Broad ICP Compatibility: Direct replacement for Heil, Tempstar, KeepRite, and Day & Night furnaces, reducing the need for universal workarounds.
- Automatic Reset Logic: Features a 40°F differential, automatically resetting at 150°F to restore system operation without manual intervention.
- OEM Reliability: Built to original manufacturer specifications to maintain the safety certification and airflow efficiency of the equipment.
Common Service Questions:
What causes a 190F limit switch to trip frequently?
Frequent tripping is typically symptomatic of restricted airflow. Technicians should inspect for a clogged furnace filter, blocked return air ducts, or a failing blower motor that is not moving enough CFMs across the heat exchanger.
Can I test the 1183523 limit switch with a multimeter?
Yes. With the power disconnected and the switch at room temperature, it should show continuity (0 ohms) across the terminals. If the circuit is open at room temperature, the bimetal disc is likely warped or defective and requires replacement.
Is this switch compatible with 80% AFUE gas furnaces?
Yes, this switch is commonly found in 80% AFUE mid-efficiency gas furnaces, including N80 and F8M series units, where the 190°F threshold is standardized for safety.
