International Comfort Products 1320447 Rollout Switch 300°F Limit Safety Control

The International Comfort Products 1320447 is a rollout safety switch designed to protect gas furnaces from dangerous flame rollout conditions. This limit switch monitors flue temperatures and automatically shuts down the burner if temperatures exceed 300°F, preventing potential fire hazards and equipment damage.

Key Features:

• 300°F temperature limit setting for reliable safety protection
• 40°F differential for proper cycling and reset
• Single-pole, auto-reset design (SB configuration)
• Direct OEM replacement for International Comfort Products furnaces
• Monitors heat exchanger and flue outlet temperatures
• Prevents flame rollout caused by blocked vents or heat exchanger cracks

This rollout switch is a critical safety component that detects abnormal heat patterns in the furnace vestibule area. When excessive temperatures are detected, the switch opens the circuit to the gas valve, shutting down burner operation until the condition is corrected and the switch resets. Proper installation and regular inspection of rollout switches are essential for safe furnace operation.
