Heil Quaker ICP 1184323 Rollout Switch

The Heil Quaker ICP 1184323 Rollout Switch is a critical safety component designed for immediate circuit interruption when burner temperatures exceed safe operating limits. Engineered as a manual reset rollout switch, this SPST (Single Pole Single Throw) device is factory-calibrated to trip at 285 degrees F, effectively cutting power to the gas valve or ignition control to prevent catastrophic heat damage or flame rollout into the cabinet. This genuine ICP replacement part ensures HVAC furnace safety by monitoring the combustion area for backdrafting or restricted flue conditions, common indicators of a compromised heat exchanger or blocked venting.

As a veteran technician knows, a tripped 1184323 flame rollout switch is a symptom, not just a failure. This OEM heater part is built for high-reliability performance in Arcoaire, Comfortmaker, Heil, and Tempstar systems. Its Normally Closed (NC) circuit opens on temperature rise, requiring a manual physical reset only after the underlying airflow or combustion issue has been diagnosed and resolved. When replacing an oxidized or weak switch, ensure the mounting position matches the factory configuration to maintain precise thermal sensing across the burner assembly.

Key Benefits

• High-Temperature Calibration: Pre-set to 285°F for accurate protection against furnace overheating.
• Precision SPST Logic: Simplified Single Pole Single Throw operation provides reliable circuit interruption.
• Manual Reset Feature: Prevents automatic cycling of a hazardous system, forcing a manual inspection of the heat exchanger and burner box.
• Cross-Brand Compatibility: Fits a wide range of International Comfort Products (ICP) equipment, including Heil Quaker, KeepRite, and Day & Night models.
• Safety Compliance: Designed to meet OEM specifications for flame rollout detection and fire prevention.

Common Questions

Why does my rollout switch keep tripping?
Frequent tripping usually indicates a restricted flue, blocked secondary heat exchanger, or improper gas pressure. Check the inducer motor and venting for obstructions before resetting the 285-degree rollout switch.

Can I bypass a manual reset switch to test the furnace?
Never bypass this safety device. If the ICP 1184323 has opened, it has detected a dangerous thermal condition. Bypassing it can lead to fire or carbon monoxide leaks.

Is the 1184323 compatible with other ICP brands?
Yes, this part is a standard safety component for multiple brands under the International Comfort Products umbrella, including Tempstar, Comfortmaker, and Arcoaire furnaces requiring a 285F M/R SPST limit.
