The K-STAR island range hood K-1013 electronic button may be
predisposed to damage from grease buildup due to the fact that it
shares the same space as the air drawn in and the button circuit panel
housing is not sealed. It may be possible to prevent this by removing
the button circuit panel from its housing, wrap the circuit panel
loosely with one layer of plastic food wrap such as Seran Wrap, place
back inside its housing and install. This solution is my own
invention, still experimental and may not yield results for many
years.
