Heil Quaker ICP 1177660 Switch
The Heil Quaker ICP 1177660 Switch is a high-reliability OEM furnace limit switch engineered for International Comfort Products (ICP) heating systems. As a critical safety component, this temperature limit switch features an auto-reset design, specifically calibrated with a 150?F opening point and a 100?F closing point (L150-50 for differential logic). This HVAC replacement part is essential for preventing heat exchanger damage and ensuring system integrity during high-thermal events. Designed for a furnace limit circuit, its precise bimetal disc actuation provides a dependable response when the plenum temperature exceeds safe operating parameters. This switch is a direct replacement for various Heil Quaker furnace parts used in models from Tempstar, Comfortmaker, and Arcoaire. Utilizing a genuine ICP 1177660 ensures secondary diagnostic accuracy, helping technicians clear 4-flash or 7-flash furnace error codes. This HVAC safety switch is built for heavy-duty cycling, maintaining the strict electrical specifications required for ICP HVAC troubleshooting and long-term furnace maintenance in residential and light commercial applications.
Key Benefits- Precise Thermal Calibration: Features a factory-set 150-degree opening and 100-degree closing threshold to maintain optimal safety and prevent system overheating.
- Plug-and-Play OEM Fit: Designed as a direct ICP 1177660 replacement, eliminating the need for mounting modifications or terminal adjustments in compatible Heil Quaker units.
- Automatic Reset Logic: The auto-reset limit switch restores circuit continuity automatically once temperatures drop, reducing unnecessary service calls for minor airflow fluctuations.
- System Protection: Actively monitors for restricted airflow caused by dirty filters or blower failure, protecting the primary heat exchanger from stress and cracking.
What causes this limit switch to trip frequently?
In most HVAC diagnostics, frequent tripping is caused by restricted airflow. Check for a dirty air filter, blocked return air ducts, or a failing blower motor. If the unit continues to trip after addressing airflow, the bimetal disc in the limit switch may have weakened over time.
Is the ICP 1177660 compatible with other brands?
Yes, as an International Comfort Products component, it is compatible with many brands under the ICP umbrella, including Heil, Tempstar, Comfortmaker, Arcoaire, and KeepRite. Always verify the L-rating (L150-50) against the original part before installation.
How do I test if this switch is defective?
Technicians should use a multimeter to check for electrical continuity across the terminals. At room temperature, the 1177660 switch should remain closed (showing continuity). If the switch is open (no continuity) while cool, it is defective and requires immediate replacement.
