Heil Quaker ICP 1191275 Limit Switch
The Heil Quaker ICP 1191275 Limit Switch is a critical OEM replacement part designed for precision thermal monitoring in high-efficiency furnace heating cycles. Engineered as an L205F-40 limit switch, this snap-action SPST furnace safety control features a fixed set point, opening the circuit at 205?F and closing once the temperature drops by a 40?F differential (165?F). This auto-reset high limit switch is essential for protecting the heat exchanger from structural damage and ensuring the HVAC blower motor operates within safe parameters. Built with 1/4" quick-disconnect terminals and a durable bimetal disc, the International Comfort Products 1191275 provides a direct fit for Heil, Tempstar, and Comfortmaker units. This industrial-grade component eliminates intermittent furnace short cycling caused by worn-out or out-of-calibration safety sensors. For contractors performing HVAC troubleshooting, this genuine ICP part maintains system integrity without the reliability risks associated with generic after-market alternatives.
Key Benefits- OEM Compatibility: Precision-matched for Heil Quaker, KeepRite, and Tempstar heating systems.
- Automated Safety: Features an auto-reset function to restore system operation once safe temperatures are reached.
- Heavy-Duty Construction: Designed with a 60T electrical rating and welded components for long-term current-carrying integrity.
- System Protection: Acts as a primary failsafe to prevent heat exchanger overheating and potential secondary damage.
- Why is my furnace short cycling with this part? If the 1191275 limit switch trips frequently, check for restricted airflow, such as a clogged MERV filter or a failing inducer motor, rather than assuming the switch is faulty.
- Can I use a manual reset switch instead of this L205F-40? No. This is an auto-reset safety control. Replacing it with a manual reset or a different temperature rating can lead to system failure or unsafe operating conditions.
- How do I verify the switch is bad? Use a multimeter to check for electrical continuity across the terminals. At room temperature, the circuit should remain closed.
