Heil Quaker ICP 1171325 Rollout Switch

The Heil Quaker ICP 1171325 Rollout Switch is a critical safety component designed for furnace flame rollout protection. This SPST (Single Pole Single Throw) safety switch is engineered to interrupt the heating cycle if it detects sustained thermal exposure near the burner assembly, preventing hazardous conditions caused by restricted venting or heat exchanger failure. Operating with high-precision thresholds, the ICP 1171325 features a 195-degree F open temperature and an 80-degree F close temperature, allowing the automatic reset furnace switch to return to a closed state once temperatures normalize. As a genuine ICP OEM replacement part, it ensures direct compatibility with specific Tempstar, Comfortmaker, and Heil gas furnaces, such as the PGH036 and PGE036 series. This 195F 80F differential switch is essential for maintaining equipment integrity and ensuring your system meets original manufacturer specifications during routine HVAC safety switch troubleshooting or emergency repairs.

• Precision Safety: Calibrated to trigger at 195?F to prevent overheating and potential fire hazards.
• Automatic Reset: Self-correcting design eliminates the need for manual intervention once the cabinet cools to 80?F.
• OEM Compatibility: Guaranteed fit for a wide range of International Comfort Products (ICP) and Heil Quaker equipment.
• Durable Construction: Built to withstand the harsh thermal environment of a burner box without premature fatigue.
• Standardized Logic: SPST configuration integrates seamlessly with most modern furnace control boards.

What causes a rollout switch to trip on a Heil furnace?
A trip is typically caused by "flame rollout," where combustion gases are pushed back toward the burners due to a cracked heat exchanger, soot-blocked internal passages, or a failure in the inducer motor/venting system.

Is the ICP 1171325 a manual or automatic reset switch?
This specific model is an automatic reset switch, meaning it will re-close the circuit once the local temperature drops below 80?F, unlike manual versions that require a physical button press.

How do I test my furnace rollout switch for continuity?
With power disconnected, use a multimeter set to Ohms. At room temperature, the 1171325 should show continuity (0 Ohms or a "beep"); if the circuit is open while cool, the switch has failed and requires replacement.
