7.3 Replacing Component Box Components
1. Remove the control panel (see steps 1 and 2 of section 7.2 on preceding page).
2. Unplug the wiring harness from the 15-pin connector on the interface board and disconnect the
grounding wire from terminal adjacent to the 15-pin connector on the back of the controller.
Remove the control panel assembly by lifting it from the hinge slots in the control panel frame.
3. Disconnect the wiring from the component to be replaced, being sure to make a note of where
each wire was connected.
NOTE: If replacing the interface board, connectors J1 and J2 must also be disconnected from
the 12-pin connectors on the rear of the component box, directly behind the interface board.
4. Dismount the component to be replaced and install the new component, being sure that any
required spacers, insulation, washers, etc. are in place.
NOTE: If more room to work is required, the control panel frame and top cap assembly may be
removed by removing the hex head screws that secure it to the fryer cabinet (see illustration
below). If this option is chosen, all control panel assemblies must be removed per steps 1 and 2
above. The cover plate on the lower front of the component box may also be removed if desired.
Removing the component box itself from the fryer is not recommended due to the difficulty
involved in disconnecting and reconnecting the oil-return valve rods, which pass through
openings in the component box.
Remove these three
screws at each end.
Remove these two screws
from the center supports.

5. Reconnect the wiring disconnected in step 3, referring to your notes and the wiring diagrams on
the fryer door to ensure that the connections are properly made. Also, verify that no other wiring
was disconnected accidentally during the replacement process.
6. Reverse steps 1 and 2 to complete the replacement and return the fryer to service.
