Product Details

Description

This high-quality Flame Rollout Switch is a critical safety component designed for residential gas furnaces and HVAC heating systems. Engineered to monitor the temperature near the burner assembly, this thermal limit switch automatically interrupts the furnace's heating cycle if it detects excessive heat—specifically reaching an opening threshold of 350 degrees Fahrenheit. This prevents hazardous flame rollout conditions often caused by venting issues, blockages, or heat exchanger failures. Featuring a manual reset design, this safety sensor ensures that the heating system cannot restart until the underlying issue has been professionally inspected and the switch is physically reset. Ideal for furnace repair and routine HVAC maintenance, this durable switch is an essential replacement part to ensure the safe and reliable operation of your forced-air heating system.
