Heil Quaker ICP 1009169 Limit Switch

The Heil Quaker ICP 1009169 230-250F Auto Limit Switch is a critical safety component designed for precise thermal regulation within gas furnaces and technical HVAC systems. As an OEM replacement limit switch, this part is engineered to monitor heat exchanger temperatures, ensuring that the system shuts down if internal temperatures exceed the designated safety threshold. This specific model features an operating range of 230?F to 250?F and utilizes an automatic reset mechanism, which restores the circuit once the unit cools back down to a safe operating level. Built for high-cycling reliability, the ICP 1009169 is a direct-fit solution for various Heil, Quaker, International Comfort Products, and Kenmore furnace models. This furnace high limit switch prevents equipment damage and potential safety hazards by maintaining strict air temperature control during the heating cycle, making it an essential stocked item for maintenance professionals and contractors working with gas furnace replacement parts.

• Universal HVAC Compatibility: Serves as a primary furnace limit control for numerous ICP-manufactured brands including Heil, Tempstar, and Comfortmaker.
• High-Temperature Protection: Specifically calibrated with a 230-250F open/close threshold to prevent heat exchanger cracking and thermal runaway.
• Automatic Reset Function: Features an integrated auto limit switch design that re-engages the heating circuit without manual intervention after cooling.
• OEM Reliability: Meets original equipment manufacturer specifications for snap-action performance and long-term durability in residential gas heating applications.

What symptom indicates a bad 1009169 limit switch?
Technicians typically look for a furnace that keeps cycling on and off (short cycling) or a blower motor that runs continuously while the burners refuse to ignite, often indicating the switch is stuck open or tripped due to airflow issues.

Can I use a manual reset switch to replace this auto-reset version?
No. This is an automatic limit switch designed to reset itself. Replacing it with a manual version would require the homeowner to reset it physically every time it trips, which ignores the intended system sequence and safety design.

What is the difference between the 230F and 250F ratings?
These figures represent the temperature differential. The switch is designed to trip or "open" the circuit when the temperature hits the upper limit (250?F) and close again once it has cooled to the lower threshold (230?F).
