NOTE : The following components and subassemblies
are to be found in the upper portion of the
steamer
2.1.20 Timer Assembly
P/N 100983
Timer Fastener Nut
P/N 101145
1. Remove knob from the timer. Under the knob is
a hexagonal nut which holds time mechanism to
the steamer’s front panel. Note that there is a
FLAT side on the time shaft and that this flat is
facing upward.
2. From the left side, unplug the five terminals/
wires (violet, gray, black, tan and white.) from the
time mechanism and unplug the two black timer
motor leads.
3. With a 26mm open ended wrench, remove the
hex nut holding the timer in place. The timer may
then be removed from the front panel.
4. Notice: Right below the timer shaft, the timer
has a small plastic anti-rotation tab molded into
its case. There is a corresponding hole punched
in the steamer’s sheet metal panel. This hole
may be seen only when the timer is removed.
To Install:
5. Fit the timer in place, ensuring that it is set so
that the anti-rotation tab on the timer fits into the
punched hole in the front panel, and that the flat
on the time shaft is again facing up. This means
that when the knob is installed, the pointer will be
exactly between the two indicators.
6. Once the timer is properly positioned, tighten the
hex nut so that it does not slip or rotate.
7. Plug the terminal wires in place (see Paragraph
2, above), and connect the two black wires from
the motor leads.
2.1.21 Control Board
P/N 119801
1. Turn off electrical power to the steamer.
2. Remove the protective control panel cover.
3. Unplug the connectors from the rear of the
board.
4. Unplug and remove connectors which are
jumper plugs and NOT connected to the wiring
harness. These will be required for the
installation of the new board.
5. The circuit board is held in position by five
plastic retainer clips.
6. To remove, squeeze the flared tabs on the clips
one by one to release the clips from the hole in
the circuit board. Be careful to hold the board so
that it does not drop. Do not squeeze the clips
too tight, since this could damage the clips.
To Install:
7. Position the board against the five clips and
press each corner in one by one until tabs on
each clip clear the holes in the circuit board.
8. Insert jacks in the same connector locations as
those from which removed. Press firmly to be
sure the jack is fully seated on the board.
9. Install the protective control panel cover.
2.1.22 Fan
P/N 106354
IMPORTANT : Make sure it has come to a complete
stop before working on the fan.
1. To remove the fan from either cavity, open the
door and remove the pan support wire rack in
front of the fan.
2. With a 3mm Allen wrench, loosen the set screw
holding the fan to the motor shaft.
3. Grasp the fan, and with a slight rocking motion
pull it off from the motor shaft.
To Install:
4. Note that the motor shaft has a flat surface.
Position the fan hub on the motor shaft so that
the 3mm Allen set screw is opposite the flat
portion of the motor shaft.
5. Slide the fan onto the motor shaft far enough so
that the motor shaft is at the end of the fan hub.
6. With a 3mm Allen wrench, tighten the set screw
onto the fan.
NOTICE : Advise customers to clean the fan blades
periodically of deposited food grade grease coming
from the foods being cooked. The deposit of such
grease over time could cause the fan to vibrate.
