Heil Quaker ICP 1065295 Limit Switch

The Heil Quaker ICP 1065295 Limit Switch is a critical OEM replacement part designed for precision thermal regulation in residential and commercial furnaces, heat pumps, and air handlers. Engineered for automatic operation, this 105-135F Auto Limit Switch monitors heat exchanger temperatures to facilitate safe equipment cycles. With a cut-out temperature of 105°F and a cut-in temperature of 135°F, it serves as a primary safety boundary against overheating, ensuring the burner assembly remains within manufacturer-defined parameters. This durable disc limit switch features a 1-inch outer diameter and replaces legacy ICP part numbers including 1320335, 1320539, 613839, and 700628. As a genuine FastParts HVAC component, it maintains compatibility across several brands under the International Comfort Products umbrella, including Tempstar, Comfortmaker, Arcoaire, and KeepRite. Installing this high-limit safety switch is essential for resolving furnace short cycling issues and protecting the heat exchanger from thermal stress, allowing for reliable HVAC system diagnostics and long-term performance.

• Universal Brand Compatibility: Direct-fit replacement for Heil, Quaker, Tempstar, Comfortmaker, Arcoaire, and Kenmore furnace models.
• Automatic Reset Function: Eliminates manual intervention by resetting the circuit once the temperature falls back into the safe 105-135°F operating window.
• Standardized Disc Sizing: Features a 1" outer diameter for seamless mounting in standard heat exchanger limit ports.
• OEM Precision: Maintains original equipment specifications to prevent nuisance tripping and ensure accurate thermal response.
• Safety Integrity: Acts as an essential fail-safe to cut power to the gas valve if airflow is restricted or temperatures exceed safe limits.

How do I know if my ICP 1065295 limit switch is bad?
Technicians should check for continuity using a digital multimeter while the switch is at room temperature. If the circuit remains open when cool, or if the furnace is frequently short cycling despite adequate airflow, the switch likely requires replacement.

What causes this limit switch to trip repeatedly?
While the switch itself may fail over time, repeated tripping often indicates restricted airflow. Check for a dirty furnace filter, blocked return air ducts, or a failing blower motor that is preventing heat dissipation from the exchanger.

Can I use this switch in both gas and electric units?
Yes, the 1065295 is designed for use in various ICP-manufactured equipment, including gas furnaces and air handlers, provided the thermal requirements match the 105-135°F specification.
