Heil Quaker ICP 1175972 Limit Switch

The Heil Quaker ICP 1175972 Limit Switch is a critical safety component designed for International Comfort Products (ICP) heating systems. This L160-100 limit switch features a 160°F opening temperature and a 100°F closing temperature, providing precise thermal regulation to prevent heat exchanger damage or unsafe operating conditions. As a genuine OEM replacement part, it ensures exact fitment and electrical compatibility for Heil Quaker furnaces, Arcoaire, Comfortmaker, and Tempstar units. This bimetal disc temperature control utilizes a snap-action SPST switch that opens on temperature rise, effectively interrupting the gas valve circuit if the plenum exceeds safe limits. Its auto-reset functionality allows the furnace high limit switch to re-engage once the system cools to the 100°F differential setpoint. For technicians, the 1/4 inch quick-disconnect terminals and standard snap disc mounting facilitate efficient field installation and HVAC furnace troubleshooting.

• OEM Reliability: Direct ICP 1175972 replacement ensures consistent performance and maintains the original engineering specifications of the HVAC cabinet.
• Precise Thermal Protection: Fixed 160 degree limit switch calibration prevents short-cycling and protects the heat exchanger from thermal stress.
• Broad Compatibility: Supports a wide range of Heil Quaker, Day & Night, and KeepRite residential furnace models.
• Rugged Construction: Features a durable bimetal disc design engineered for high-cycle industrial and residential applications.

• What are the symptoms of a failing limit switch? Common indicators include a furnace that cycles on and off (short-cycling) or a blower fan that runs continuously because the limit control cannot signal a safe cooling state.
• Will this fit my specific furnace model? The 1175972 is a standard ICP limit switch; however, always verify the temperature stamps on your existing part to ensure a 160-100 range is required.
• Is this an auto-reset or manual-reset switch? This is an auto-reset limit switch, meaning it will automatically close the circuit once the temperature drops back down to 100°F.
