6.2.2 Error Messages and Display Problems
Problem Probable Causes Corrective Action
M2000 display is in
wrong temperature
scale (Fahrenheit or
Celsius).
Incorrect display option
programmed.
M2000 computers may be
programmed to display in either
Fahrenheit or Celsius. Refer to the
separate M2000 Computer Operation
Manual for instructions on changing
the display.
M2000 display
shows
HI.
Fryer is 15ºF (8ºC) above setpoint.
This display will appear only if the
fryer is in the non-dedicated mode
and the frypot temperature rises 15°
(8°C) or more above the
programmed setpoint. This indicates
a problem with the temperature
control circuitry. Turn the fryer off
and call FASC.
M2000 display
shows
HOT.
Frypot temperature is more than
410ºF (210ºC) or, in CE countries,
395ºF (202ºC).
This in an indication of a
malfunction in the temperature
control circuitry, including a failure
of the high-limit thermostat. Shut
the fryer down immediately and call
FASC.
M2000 display
shows
LOW TEMP.
Frypot temperature is between
180°F (82°C) and 315°F (157°C).
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. Shut the
fryer down and call FASC.
M2000 display
shows
PROBE
FAILURE.
Problem with the temperature
measuring circuitry including the
probe.
This indicates a problem within the
temperature measuring circuitry that
is beyond the scope of operator
troubleshooting. Shut the fryer
down and call FASC.
M2000 display
shows IGNITION
FAILURE.
Open drain valve, failed computer,
failed interface board, open high-
limit thermostat.
This indicates that the fryer is not
heating. It is displayed if the fryer
loses its ability to heat oil. It is also
displayed when the oil temperature is
above 450°F (232°C) and the high-
limit thermostat has opened, halting
the heating of the oil. Verify that the
drain valves are fully closed. If this
does not correct the problem, call
your FASC.
M2000 display
shows HI-LIMIT.
Computer in high-limit test mode.
This is displayed only during a test
of the high-limit circuit and indicates
that the high-limit has opened
properly.
