previous page. D. One or more other components
have failed.
D. 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.
Fryer does not heat
after filtering. Drain valve is open.
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 drain
valve is fully closed.
Fryer heats until
high limit trips with
heat indicator ON.
Temperature probe or computer has
failed. Call FASC.
Fryer heats until
high limit trips
without heat
indicator ON.
Contactor or computer has failed Call FASC.
Fryer stops heating
with heat indicator
ON.
The high limit thermostat or
contactor has failed.
The fact that the heat indicator is
ON indicates that the computer is
functioning properly and is calling
for heat. The high limit thermostat
functions as a normally closed
switch. If the thermostat fails, the
"switch" opens and power to the
elements is shut off. If the
contactor fails to close, no power is
supplied to the elements.
Determining which component has
failed is beyond the scope of
operator troubleshooting.
Call FASC.
