This Flame Rollout Switch is a vital safety component designed for gas-fired heating systems and furnaces. Functioning as a thermal safeguard, it is engineered to monitor the temperature near the burner assembly. If the system detects a 'rollout' condition—where flames escape the combustion chamber due to a blockage or heat exchanger failure—this switch triggers at a precise 240°F threshold. Upon reaching this temperature, the switch opens the electrical circuit to immediately shut down the gas valve, preventing fire hazards and further equipment damage. This high-quality replacement part is essential for maintaining the safe operation of residential and commercial HVAC units, ensuring your heating system complies with standard safety protocols.
