International Comfort Products 1177214 Rollout Switch

The International Comfort Products 1177214 Rollout Switch is a control component used in furnace systems to detect flame rollout conditions near the burner assembly. It operates as a temperature-sensitive limit switch that opens the electrical circuit when excessive heat is detected, shutting down the gas valve. It is installed inside gas furnaces and heating units particularly in commercial HVAC systems. It serves as a protective system integrated into the safety interlock to maintain controlled shutdown during combustion irregularities.
