Corrective Action
This display is normal when the
fryer is first turned on and may
appear for a short while if a large
batch of frozen product is added to
the frypot. If the display never
goes out, the fryer is not heating.
Look for a decimal in the LED
display between digits 1 and 2. If
the decimal is present, the
computer is calling for heat and is
functioning properly. See Fryer
Does Not Heat in Control and
Heating Problems (Section 6.2.1).
If the decimal is not present, the
computer is not calling for heat and
may be malfunctioning. If
available, substitute a controller
known to be working for the
suspect computer. If the fryer
functions correctly with the
substitute computer, order a
replacement computer from your
FASC.
This indicates a problem within the
temperature measuring circuitry
that is beyond the scope of
operator troubleshooting. Shut the
fryer down and call FASC.
The CM III computer may be
programmed for constant
temperature display or countdown
timer display. Refer to the separate
Frymaster Fryer Controllers
User's Manual for instructions on
toggling between these display
options.
This in an indication of a
malfunction in the temperature
measuring or control circuitry,
including a failure of the high-limit
thermostat. Determining the
specific problem is beyond the
scope of operator troubleshooting.
Shut the fryer down immediately
and call FASC.
