Description
The York S1-02634027000 Flame Rollout Limit Control Switch is an efficient component used in gas-fired furnaces and unit heating systems to protect against unsafe flame conditions. It is positioned near the burner as a sensor where it monitors excessive heat or abnormal flame movement that could indicate a blocked heat exchanger, low venting in HVAC systems. When temperatures are detected, the switch opens the control circuit and shuts down the heating cycle to prevent fire. It provides an essential shutdown during ignition and operation of commercial heating systems.
