2. Lowering the front panel, a washer/nut assembly
can be located at each corner (front right & front
left, right behind the hinges the panel swings
on). These nut assembles need to be loosened
because they hold down the bottom plenum of
the control assemble. See photo. Nut/washer
placement is indicated by white X’s.
3. After the 2 nuts are loose in front and all eight
screws are removed from the back of the control
assembly, you can slide the control assembly
out of the back of the unit. (Notice the assembly
will only slide back for about an inch. Then it
will "get stuck". Do not continue to “tug” on
the assembly. The various wire harnesses will
stop the control assembly from being able to be
slide out completely. Jerking or tugging will
cause wires to be separated from connectors!)
