The 5/8" Flame Rollout Switch is a critical safety component designed for gas-fired heating systems such as furnaces, boilers, and water heaters. This thermal limit switch acts as a vital guardian for your HVAC equipment, specifically engineered to detect 'rollout' conditions where flames escape the combustion chamber due to blockages or heat exchanger issues. With a fixed trip temperature of 270°F, this sensor promptly interrupts the electrical circuit to shut down the burner if dangerous temperatures are detected. Featuring a manual reset design, this switch requires a physical inspection of the heating unit before operation can resume, ensuring that the underlying cause of the overheating is addressed. This durable disc-style sensor is a standard replacement part for maintaining the safe and efficient operation of residential and commercial heating appliances.
