ELECTRONIC OVEN CONTROL TEST MODES
HANDLING THE BOARDS
The Touch Control Board and the Display Head
are subject to failure if static electricity is trans-
ferred to the components during handling. When
handling these parts, use a grounding 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:
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 microprocessor chips
(see Figure A).
Display Head
Handle the Display Head only by the edges of the
plastic frame. DO NOT TOUCH the connector
pins, the microprocessor chip, or jumper wires
(see Figure B).
IMPORTANT NOTE: Repack the old boards
in the antistatic bags before returning them
to a parts distributor.
