International Comfort Products 1176905 Disc Limit Switch 165F

Product Description

The INTERNATIONAL COMFORT PRODUCTS 1176905 is a disc-type limit switch rated at 165 degrees F, designed to regulate and monitor temperature in residential gas furnace systems. When the heat exchanger or supply air reaches the rated threshold, the switch opens the control circuit to prevent overheating and protect downstream components. At 4.1 inches long, 3.4 inches wide, and 1.6 inches tall, it is a compact, direct OEM replacement that maintains the original equipment specifications. Licensed HVAC technicians are the primary installers of this component during furnace service or safety-control replacement procedures.

This limit switch is suited for residential gas furnace applications where disc-style high-limit controls are required. It regulates supply-air temperature to protect the heat exchanger and connected ductwork. Verified compatible models include G80CTL0701412A1, F8MTL0701412A1, and G8MVL0701412A1. Always confirm the model number and existing switch configuration before ordering a replacement.

Key Features

• Disc-style form factor matches OEM mounting footprint
• 165 degrees F trip rating provides a defined high-limit cutoff for furnace temperature control
• Compact dimensions — 4.1 inches x 3.4 inches x 1.6 inches — fit original switch location without modification
• Genuine OEM replacement part engineered to original manufacturer specifications
• Protects heat exchanger and system components from thermal damage during operation

Compatibility

Confirmed compatible with furnace models G80CTL0701412A1, F8MTL0701412A1, and G8MVL0701412A1. Verify the existing part number and temperature rating on the original switch before installation to confirm fitment.

Installation Notes

Installation should be performed by a licensed HVAC technician. Before replacing the limit switch, shut off all power to the furnace at the disconnect switch and allow the heat exchanger to cool completely. Follow local mechanical and electrical codes, including applicable IFGC requirements, when servicing gas furnace controls. Do not bypass or jumper the limit switch during diagnostics for extended periods, as this removes the primary high-temperature safety protection from the system.
