The PCB is held in place with six #6 Nylok nuts and plastic insulator washers. Use a
5/16" nut driver to remove the nuts. The PCB and washers are now free to slide off
the threaded studs.

Beneath the PCB are six plastic standoffs. If they are crushed, replace them before
reassembly.
•
To install the PCB, make certain that six plastic standoffs are present on the control
panel studs.
•
Slide the board onto the studs
•
Install six plastic washers onto the studs securing the circuit card.
