COMPONENT REMOVAL
Control Board (Model 601F)
The control board is held in position by two sets of tabs
behind the left side of the control panel. The two for-
ward tabs position the LCD in the control panel window,
while the other two tabs secure the middle of the con-
trol board. The control board is then shielded by a con-
trol enclosure, and concealed by the light diffuser.
To access and remove the control board, the light dif-
fuser must first be removed. Now extract the screws
securing the control enclosure to the ceiling of the com-
partment. Then, lower the back of the enclosure while
pulling it toward the rear of the unit. Disconnect all
electrical leads attached to the control board, including
the membrane switch wire harness. Expand the two
tabs at the middle of the control board outward while
pulling the back of the board down slightly. Then,
expand the two forward tabs outward that hold the LCD
in position, and pull the control board down and toward
the rear of the unit. (See Figures 7-31 & 7-32)
Control Panel (Model 601F)
The control panel, which houses the membrane switch,
is secured to the ceiling of the compartment by two
rows of screws. The front row of screws are through
keyhole slots in the assembly. To access and remove
the control panel, the light diffuser and control enclo-
sure must be removed first.
NOTE: It is recommended, but not necessary, to
remove the control board in order to remove the control
panel. If leaving the control board secured to the con-
trol panel, all electrical leads attached to the control
board must be disconnected. (See Figure 7-32)
Now, extract the screws at the back of the control
panel. Then, loosen the screws in the keyhole slots
toward the front of the control panel. Push the panel
back, then lower the panel down and out. (See Figure
7-31)
