E – Drain or return valve is not in desired state. The display will alternate between E and the corresponding vat
number. Ensure the actuator is plugged in and an error does not exist.
– Three horizontal lines indicate the AIF temperature sensor did not detect that the vat was full during
auto filtration.
n – Network Error - An “n” displays for 10 seconds if no communication is received from the cooking
computer within ten seconds after a power on or MIB reset.
P – Pan Switch – Filter pan is improperly seated. Filtration is suspended.
r – Reset Switch - Reset the vat closes all of the valves on the vat. If displayed for some time, there is probably
a problem with the board.
1 – 5 – Numbers which correspond to the vats with either an “L” indicating the left side of a split vat or “r”
indicating the right side of a split vat or a full vat. These numbers are displayed in manual mode.
1.11.6 Replacing the MIB Board
Disconnect the fryer from the electrical power supply. Remove the torx screws from the MIB cover, exposing
the MIB board (see Figure 11). Removing the screw at top center lets the MIB board hinge down. Carefully
remove the plugs on the rear of the board (see Figure 12). Replace with a new MIB board and reverse steps to
reassemble. Once replaced, CYCLE POWER TO ENTIRE FRYER SYSTEM. See next section to reset
control power. Check software version # and if necessary update the software. If a software update was
necessary, follow the instructions to update the software on in section 1.15 ensuring the MIB reset button is
pressed and held for five seconds at the end of the update to update the MIB.

1.11.7 Control Power Reset Switch
The control power reset switch is a momentary
rocker switch located behind the control box
(see Figures 13 and 14) above the JIB that
resets all power to all the computers and boards
in the fryer. It is necessary to reset all power
after replacing any computer or board. Press
and hold the switch for at least ten seconds
when resetting the control power to ensure
power has sufficiently drained from boards.
