Heil Quaker ICP 1176902 Limit Switch
The Heil Quaker ICP 1176902 Limit Switch is a critical furnace safety control designed for International Comfort Products (ICP) equipment. As a genuine OEM replacement part, this 200°F CO auto limit switch serves as a primary high-limit safety, monitoring internal plenum temperatures to prevent thermal overstress components. When temperature thresholds exceed 200 degrees Fahrenheit, the switch triggers an automatic cut-out, interrupting the burner circuit until safe operating conditions are restored. This automatic reset functionality ensures the system maintains precise cycle control without requiring manual intervention after a temporary temperature excursion. For contractors servicing Heil, Quaker, or KeepRite units, installing the ICP 1176902 ensures the system operates within original factory specifications, maintaining the pressure and heat balance required for efficient HVAC heat exchanger protection. Replacing a drifted or cycling high limit sensor restores the factory safety sequence and prevents nuisance tripping in residential gas furnaces.
Key Technical Benefits
- Genuine OEM Specification: Engineered specifically for Heil Quaker furnace parts compatibility to match factory airflow resistance and thermal response times.
- Precise 200°F Cut-Out: Provides accurate high limit protection, preventing damage to the heat exchanger and surrounding components during restricted airflow events.
- Automatic Reset Logic: Features a CO (Cut-Out) auto limit design that restores the circuit once temperatures drop below the specified differential.
- Rugged Industrial Build: Constructed to withstand the high-cycle thermal demands of residential heating systems and light commercial blowers.
- Seamless Integration: Standard mounting footprint allows for rapid furnace limit switch replacement, reducing labor time on the job site.
Common Questions
What causes a 200°F limit switch to trip repeatedly?
Nuisance tripping of the ICP 1176902 often indicates restricted airflow, such as a dirty 1-inch pleated filter, a failing blower motor, or obstructed return air ducts. If the switch remains open, it likely requires replacement to restore furnace burner ignition.
Is this switch compatible with other ICP brands?
Yes, the 1176902 limit switch is a standard safety component used across several International Comfort Products brands, including Heil, Tempstar, Comfortmaker, and KeepRite. Always verify the part number against the unit’s specific wiring diagram.
Can I use a higher temperature limit switch instead of this 200°F model?
No. Safety controls must never be bypassed or substituted with different temperature ratings. Using a higher-rated switch can lead to dangerous overheating and potential heat exchanger failure.
