1.11.7 Control Power Reset Switch
The control power reset switch is a momentary
rocker switch located behind the control box,
(see Figures 6 and 7) above the JIB, which
resets all power to all the controllers and
boards in the fryer. It is necessary to reset all
power after replacing any controller 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.
