Problem Probable Causes Corrective Action
A. The high-limit thermostat has failed
and displays
, or the
contactor has failed.
A. 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.
Fryer stops heating
with heat indicator
ON.
B. Tilt switch is up or defective.
B. Make sure that the elements are
completely lowered.

circuitry.
Verify that the drain valve is fully
closed. The fryer will not function if
the drain valve is not fully closed. If
the drain valve is fully closed, the
problem is either the high-limit
thermostat or within the latching
circuitry and is beyond the scope of
operator troubleshooting. Call FASC.
Display shows .
Fryer is more than 21°F (12°C) above
setpoint.
This display is normal if the fryer
setpoint has been changed to a lower
temperature. The display should
revert to the normal four dashes when
the frypot temperature cools to the
setpoint. If the setpoint has not been
changed, this indicates a problem with
the temperature control circuitry.
Turn the fryer off and call FASC.
