Model overview
Viking currently lists VBCV53638 as a 36"W. 18"H. Built-In Custom Ventilator.

Viking places this model in the 5 Series collection.
When requesting service for VBCV53638, note whether the issue is constant or intermittent, what function still operates normally, and whether the condition followed cleaning, installation work, a power event, weather exposure, plumbing work, or another change relevant to this appliance.
