International Comfort Products 1191124 Limit Switch Assembly

Product Description

The INTERNATIONAL COMFORT PRODUCTS 1191124 is a limit switch assembly designed to protect heating equipment from overheating conditions. It monitors internal temperatures continuously during furnace operation and interrupts the electrical circuit to the burner or control system when temperatures exceed a preset threshold. Once temperatures return to a safe operating range, the switch resets either automatically or manually depending on configuration. Licensed HVAC technicians typically install or replace this component during routine furnace servicing or when temperature control response becomes unreliable.

This limit switch assembly is installed within the heat exchanger section of a gas furnace, where it senses operating heat levels throughout each heating cycle. It serves as a critical safety control, preventing sustained high-temperature conditions that could damage the heat exchanger or associated components. Replacement is common when the switch fails to respond consistently within its specified operating range, causing nuisance trips or failure to interrupt the circuit when required.

Key Features

• Interrupts burner or control circuit power when internal temperatures exceed the preset limit
• Continuous temperature monitoring throughout furnace operation
• Supports automatic or manual reset depending on unit configuration
• OEM-style replacement for consistent safety control performance
• Designed for installation at the heat exchanger in residential gas furnace applications

Compatibility

Designed as an OEM-style replacement limit switch assembly for residential gas furnace heating systems.

Installation Notes

Installation should be performed by a licensed HVAC technician. Before servicing, shut off electrical power to the furnace at the disconnect or breaker and allow the heat exchanger to cool completely before handling the switch. Verify the replacement switch matches the original setpoint and reset configuration before reinstalling. Work should comply with applicable local mechanical and electrical codes.
