Fryer repeatedly
cycles on and off when
first started.
Fryer is in melt-cycle mode.
This is normal for fryers equipped
with CM III.5 computers and Digital
Controllers. The default operational
mode for these controllers is for the
elements to cycle on and off until the
temperature in the frypot reaches
180°F (82°C). In CM III.5 computers,
CYCL will appear in the display
when in the melt-cycle mode Refer to
the separate Frymaster Fryer
Controllers User's Manual for the
procedure for canceling the melt-cycle
for the particular controller installed
on your fryer.
In fryers equipped with Solid State
(Analog) controllers, the melt-cycle is
controlled manually by means of the
rocker switch to the right of the
temperature control knob. If not using
solid shortening, press the rocker
switch to the OFF position to turn off
the melt-cycle.
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 controller has
failed.
Determining which specific
component is beyond the scope of
operator troubleshooting. Call FASC.
Fryer heats until high-
limit trips without
heat indicator ON.
Contactor or controller has failed.
Determining which specific
component is malfunctioning is
beyond the scope of operator
troubleshooting. 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 controller 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.
