Corrective Action
If available, substitute a controller
known to be working for the
suspect controller. If the substitute
controller functions correctly,
order a new controller from FASC.
If substitution of the controller
does not resolve the problem, the
most likely cause is a contactor
failed in the closed position. Call
FASC.
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.
Corrective Action
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 within the
latching circuitry and is beyond the
scope of operator trouble shooting.
Call FASC.
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.
