Beverage Air 504-672C-01 Refrigerator Defrost Heater 115V

The Beverage Air 504-672C-01 Refrigerator Defrost Heater is a component designed for compatible commercial equipment. It is placed near the evaporator coil where it operates during scheduled defrost cycles to melt accumulated frost and ice. Rated for 115V operation, it converts electrical power into heat to clear the evaporator surface and maintain unobstructed airflow. The heater supports the refrigeration system by reducing ice buildup that can interfere with normal cooling performance. It is commonly replaced during maintenance when heating output declines or the defrost cycle no longer removes frost effectively from the evaporator assembly.
