OEM part description
Genuine Sub-Zero evaporator coil for the lower refrigerator compartment of the 427R. This sealed-system component removes heat from the refrigerated drawer section as refrigerant circulates through the coil, allowing the lower compartment to maintain proper refrigerator temperatures.
Part details
The lower refrigerator compartment depends on its own evaporator to remove heat during refrigeration operation. A leaking, restricted, or damaged coil can result in poor cooling, unstable temperatures, excessive compressor run time, or loss of refrigerant from the refrigerator cooling circuit.
