OEM part description
This genuine Sub-Zero water service valve 7019463 is the electrically operated isolation valve mounted at the top of the refrigeration unit. It controls the incoming appliance water supply before water is routed to the downstream icemaker or dispenser water valves.
Part details
A failed isolation valve can interrupt water flow to downstream water components or contribute to a water leak if the valve no longer seals correctly. Symptoms can include no water reaching the icemaker or dispenser even when the downstream valve and household water supply are operating properly.
