2.21 Control Board PC Chip Replacement
[See Section 1.5 for Part Number]
1)
Disconnect power at outlet. [Pull plug.]
2)
Use a medium Phillips screwdriver to remove the four
(two-left, two-right) front control panel mounting screws.
3)
Pull panel cover/bezel up then out. It can hang from the
power switch wires.
4)
Use your Phillips screwdriver to remove the four M5
screws that mount the control overlay Plexi-panel to the
standoff posts on its Main Control Board.
5)
Allow overlay panel to hang from ribbon connection.
IMPORTANT:
The ribbon harness is fragile. Use care
when handling.
6)
Locate main Process Controller (PC) Chip on control
board, just
left of LCD
display.
7)
Use a plastic chip replacement screwdriver or the blade
of a small pocket knife to gently pry the chip from the
multi-pin chip saddle. When loose, pull the chip straight
out. See Photo 6, on page 2.
Tip:
Open freezer door.
8)
Remove any protective packaging from the replacement
chip and position it with the small notch aligned with the
notch on the chip saddle. Gently align chip pins with
saddle terminal holes and use gentle pressure to insert
chip.
Tip:
Align left set of pins with the left saddle holes,
then the right set of pins with the right set of holes in the
saddle. Then carefully press the chip into place until it is
fully seated.
IMPORTANT:
If you feel resistance, do not
force in chip pins. They are fragile and will bend.
9)
Position touchpad panel over standoff mounting posts
and secure with four M5 screws removed earlier.
10) Position front cover/bezel over lane touch pad and align
with left and right side mounting holes.
11) Secure cover/bezel with the four screws removed earlier.
