Heil Quaker ICP 1171905 Limit Switch
The Heil Quaker ICP 1171905 Limit Switch is a critical safety component designed for high-performance thermal regulation in specific furnace and air handler applications. This L140-55F limit switch functions as a primary high-limit safety, engineered to break the electrical circuit and shut down the burners if the plenum temperature exceeds the 140?F set point. Once the temperature drops below the 55?F reset differential, the switch closes to allow the ignition sequence to resume. Built to OEM specifications, this disc-style switch ensures precise mechanical actuation and long-term durability in demanding HVACR environments. It is a genuine ICP replacement part compatible with various Heil, Quaker, Tempstar, and Comfortmaker units, including the EHC20AKF3, EHC20AKB3, and EHK20AKB1 series. As a veteran technician knows, maintaining proper airflow is essential; a failing limit switch often indicates underlying issues like a clogged filter or a restricted heat exchanger rather than just a component failure.
Key Benefits for Technicians:- Precise Thermal Calibration: Factory-set at L140-55F to ensure the system operates within safe manufacture-defined parameters.
- Direct OEM Compatibility: Guaranteed fit for ICP furnace models, eliminating the mounting and wiring hurdles associated with universal "one-size-fits-all" switches.
- Enhanced System Safety: Provides reliable protection against heat exchanger cracking and potential fire hazards by preventing localized overheating.
- Durable Disc Construction: Designed for high-cycle industrial use, providing consistent limit switch performance even in high-static pressure systems.
- Why is my furnace short-cycling? If the ICP 1171905 detects temperatures above 140?F, it will trip the limit, often caused by a dirty air filter or a failing blower motor.
- Is this switch a manual or auto-reset? This is an automatic reset L140-55F switch; it will re-engage once the temperature falls to the 55?F threshold.
- Can I use this in any Heil furnace? While it fits many models like the EHK series, you must verify the specific temperature rating and part number against your unit's data plate to ensure safe operation.
