This Limit Rollout Switch is a critical safety component designed for gas furnaces and commercial HVAC heating systems. Its primary function is to monitor for 'flame rollout,' a dangerous condition where flames escape the burner assembly and heat the surrounding components. When excessive temperatures are detected outside the combustion chamber, this thermal limit switch trips to cut power to the gas valve, preventing fire hazards and equipment damage. As a vital furnace safety sensor, it ensures that your heating system operates within safe thermal parameters. This manual-reset switch is an essential replacement part for maintaining the reliability and safety of residential and light commercial gas-fired appliances.
