Heil Quaker ICP 1096985 Limit Switch

The Heil Quaker ICP 1096985 Limit Switch is a critical safety component designed for precise thermal monitoring in International Comfort Products (ICP) heating systems. This 145-150F Auto Limit Switch functions as a high-limit safety cut-out, automatically breaking the electrical circuit to the gas valve or heating elements if the plenum temperature exceeds the 150?F threshold. Engineered for professional-grade reliability, it prevents heat exchanger damage and ensures the system operates within designated thermal parameters. As an OEM HVAC replacement part, it is frequently utilized in units from brands such as Tempstar, Comfortmaker, and Arcoaire. This furnace high limit switch features an automatic reset, meaning it restores continuity once the internal temperature drops back to a safe operating level, usually around 100?F. When troubleshooting furnace short-cycling or limit switch error codes, ensuring the correct temperature rating and Heil Quaker compatibility is essential for maintaining equipment integrity and contractor-level performance standards.

Key Benefits:

• Precise Thermal Protection: Set at a 145-150F temperature range to prevent critical overheating of the heat exchanger.
• Automatic Reset Function: Eliminates the need for manual intervention by automatically resetting once temperatures stabilize.
• Broad System Compatibility: A direct OEM replacement for various ICP-manufactured brands, including Heil, Quaker, and Day & Night.
• Enhanced System Safety: Restores factory-spec safety protocols to resolve HVAC high limit trips caused by low airflow or blower failure.

Common Questions:

What causes this limit switch to trip repeatedly?
Repeated trips are usually caused by restricted airflow, such as a clogged 1-inch filter, a failing blower motor, or dirty evaporator coils. If the switch stays open despite proper airflow, the internal bi-metal disc may have fatigued, necessitating a replacement.

Can I use a higher temperature limit switch if this one keeps opening?
No. You must always match the OEM temperature rating. Installing a higher-limit switch can lead to cracked heat exchangers and creates a significant safety hazard by allowing the furnace to run at unsafe temperatures.

How do I verify if the ICP 1096985 is faulty?
A veteran tech will use a multimeter to check for continuity across the terminals when the switch is cool. If you have "no continuity" (an open circuit) at room temperature, the switch is defective and requires immediate replacement.
