Heil Quaker ICP 1095242 Limit Switch

The Heil Quaker ICP 1095242 Limit Switch is a critical OEM safety component engineered for thermal regulation in residential and commercial heating units. This furnace high limit switch features a 170?F fixed set point, serving as the primary protection against heat exchanger overheating. When internal temperatures exceed the 170?F threshold, the 1095242 limit switch breaks the electrical circuit to the gas valve, preventing equipment damage and ensuring safe operation. This ICP 1095242 replacement part is a standard 170-20 snap disc switch, meaning it opens at 170?F and automatically resets once the temperature drops by the 20?F differential. As a genuine HVAC high limit sensor, it provides the precise calibration required for Heil, Quaker, Arcoaire, Comfortmaker, and Tempstar furnaces, maintaining system integrity where universal alternatives may fail to meet exact millivolt or voltage drop specifications.

• Precise Thermal Protection: Fixed 170?F trip point ensures the burner circuit is interrupted before the heat exchanger reaches critical fatigue temperatures.
• Automatic Reset Functionality: The 20?F differential allows the Heil Quaker ICP 1095242 to resume normal operations once the plenum has safely cooled.
• Wide Application Compatibility: Designed for seamless integration into ICP 1095242 HVAC components, including various furnace limit switch assemblies and packaged units.
• OEM Structural Integrity: Constructed to endure the high-cycle demands of gas-fired and electric heating systems without drift in temperature calibration.

What causes a 1095242 limit switch to trip frequently?
Frequent cycling or "tripping" is typically indicative of restricted airflow. Check for a dirty furnace filter, blocked return ducts, or a failing blower motor that isn't pulling enough heat off the exchanger.

Is the ICP 1095242 limit switch a universal fit?
While it fits many ICP-branded units (Heil, Tempstar, Comfortmaker), you must verify the specific 170-20 SB temperature rating. Installing a switch with the wrong set point can result in unsafe operating conditions or nuisance shutdowns.

How do I test if my 1095242 limit switch is defective?
Using a multimeter, check for continuity across the terminals when the switch is cool. If the switch is open (no continuity) at room temperature, the internal snap disc has failed and the replacement limit switch is required.
