Description

International Comfort Products L150F-40 Limit Switch — SKU 1175306

The International Comfort Products (ICP) 1175306 is an OEM replacement L150F-40 Limit Switch engineered to provide dependable high-limit safety protection in ICP-brand furnaces and heating systems. As a critical safety component, this limit switch monitors heat exchanger temperatures and interrupts the burner circuit when temperatures exceed safe operating thresholds — helping prevent equipment damage, overheating, and potential hazards.

Product Overview

Designed as a direct OEM replacement, the 1175306 limit switch ensures a precise fit and reliable performance in compatible ICP furnace models. The “L150F-40” designation identifies this as a fixed high-limit control with a 150°F open setpoint and a 40°F differential, meaning the switch resets once temperatures return to a safe level. This type of automatic-reset limit switch is a standard safety device in residential and light commercial forced-air heating equipment.
