What To Do
• Cover pan with a lid.
• Turn the downdraft fan OFF until the water begins to boil.
• Pan bottoms should be flat, fairly heavyweight and
the same diameter as the surface unit selected.
• Replace the fuse or reset the circuit breaker.
• Check to see the correct control is set for the surface
unit you are using.
• See the Cleaning the glass cooktop section.
• Be sure cookware bottoms and cookware are clean
before use. Use cookware with smooth bottoms. Tiny
scratches are not removable but will become less
visible in time as a result of cleaning.
• Marks from aluminum and copper pans as well as
mineral deposits from water or food can be removed
with the cleaning cream.
• This is normal. The surface may appear discolored
when it is hot. This is temporary and will disappear
as the glass cools.
• See the Cleaning the glass cooktop section.
• Use only flat cookware to minimize cycling.
• The glass cooktop surface may seem hotter than you
are used to. This is normal. Use pans which are
absolutely flat.
• When the knob is in the OFF position, it must be pushed
down before it can be turned. When the knob is in any
other position, it can be turned without being pushed in.
• Clean filter per instructions.
• Open a window slightly to provide fresh air source.
• Remove blockage from exterior wall cap.
• Check exterior wall cap damper door for free
movement or obstruction.
• Reduce number of elbows to simplify duct run.
