Fryer repeatedly
cycles on and off
when first started.
Fryer is in melt-cycle mode
This is normal for fryers equipped
with
M2007 computers
. The
default operational mode for these
controllers is for the elements to
cycle on and off until the
temperature in the frypot reaches
180ºF (82ºC). In M2007
computers,
low temp
will
appear in the display when in the
melt-cycle mode. The melt-cycle
can be cancelled by pressing and
holding the #2 product button until
it chirps.
EXIT MLT
is displayed
with
YES NO
. Select
(1)
YES
to exit the melt cycle.
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 your FASC.
