ELECTRONIC OVEN CONTROLS

HANDLING THE BOARDS
The Touch Control Board and the Display
Head are subject to failure if static electricity is
transferred to the components during han-
dling. When handling these parts, use a ground-
ing strap, if available. If not, touch any
grounded metal surface, (e.g. the appliance
chassis), prior to handling these components.
The replacement Touch Control Board and the
Display Head are packaged in antistatic bags.
When removing the boards from their bags,
handle them as follows:
CAUTION
Power to Oven must be truned OFF
before disconnecting or reconnecting
wire harnesses to relay board, control
panel or display board.
Touch Control Board
Handle the Touch Control Board only by the
edges of the glass and the plastic frame. DO
NOT TOUCH the connector pins, or the micro-
processor chips.
Display Head
Handle the Display Head only by the edges of
the plastic frame. DO NOT TOUCH the con-
nector pins, the microprocessor chip, or jumper
wires.
IMPORTANT NOTE: Repack the old boards in
the antistatic bags and original packaging before
returning them to a parts distributor.
