Carrier 320711-303 Limit Shield R-410A Durable material composition resists degradationThe Carrier 320711 303 Limit Shield is a critical OEM component designed to protect the high limit switch from direct flame impingement and excessive heat radiation within the furnace heat exchanger assembly. Engineered for precise fitment in Carrier, Bryant, and Payne gas furnaces, this shield ensures systemic integrity by preventing premature limit switch tripping or thermal fatigue. It serves as a thermal barrier, maintaining the necessary
