Description
Overview
The International Comfort Products 1177033 is a rollout limit switch designed to protect your furnace and home from the hazards of flame rollout. When burner flames escape the heat exchanger and roll out toward the furnace cabinet, this switch detects the abnormal heat and immediately interrupts the gas valve circuit, shutting down the burner to prevent damage or fire. The L350 designation indicates a trip temperature of 350°F, and the manual reset design ensures a qualified technician must inspect and address the root cause before the furnace is returned to service — preventing repeated unsafe operation.
Key Features
- OEM replacement part for compatible International Comfort Products (ICP) furnaces
- L350 trip temperature rating — opens circuit at 350°F to halt operation during flame rollout events
- Manual reset design requires deliberate technician intervention before restart, promoting safe service practices
- Interrupts the gas valve or control board circuit to shut down burner operation immediately upon activation
- Mounts directly in the burner compartment to monitor for abnormal flame rollout conditions
- Durable construction built to withstand the high-heat environment of a furnace burner area
Application
This rollout limit switch is an OEM-specified replacement component for select International Comfort Products gas furnaces. It is commonly used during routine maintenance, safety inspections, or when diagnosing a furnace lockout caused by a tripped rollout condition. Always investigate and correct the underlying cause of flame rollout — such as a cracked heat exchanger, blocked flue, or dirty burners — before resetting and returning the unit to service.
