P.C. Board Removal

1. Disconnect oven power and remove grille, (see

"Grille" procedure).

2. Remove control panel, (see "Control Panel"

procedure).

3. Discharge high voltage capacitor, (see "High Voltage

Capacitor" procedure).

4. Disconnect ribbon connector by sliding top part of

connector upward. Once in released position remove
ribbon from connector by siding ribbon side-to-side.

NOTE:

Caution should be used when removing cable

from connector. Ribbon cable has two holes
which connector locks ribbon in place.

5. Disconnect and mark the wire connectors from p.c.

board.

6. Remove screws securing p.c. board to control panel

assembly.

7. Reassemble in reverse order.

NOTE:

Do not flex p.c. board.
