A. Power cord is not plugged in or
circuit breaker is tripped.
A. Plug power cord in and verify
that circuit breaker is not
tripped.
B. Controller has failed.
B. If available, substitute a
controller known to be working
for the suspect controller. If the
substitute controller functions
correctly, order a new controller.
Controller won't
activate.
C. Power supply component or
interface board has failed.
C. If any of the components in the
power supply system (including
the transformer and interface
board) fail, power will not be
supplied to the controller and it
will not function. Determining
which component has failed is
beyond the scope of operator
troubleshooting. Call FASC.
A. Drain valve is open.
A. This fryer is equipped with a
drain safety switch that prevents
the heating element from being
energized if the drain valve is
not fully closed. Verify that the

Fryer does not heat.
C. One or more other components
have failed.
C. If the circuitry in the fryer
control system cannot determine
the frypot temperature, the
system will not allow the
element to be energized or will
de-energize the element if it is
already energized. If the
contactor, element, or associated
wiring fails, the element will not
energize. Determining which
specific component is
malfunctioning is beyond the
scope of operator
troubleshooting. Call FASC.
