1.11 Troubleshooting
1.11.1 Control and Heating Problems
Problem
Probable Causes
Corrective Action
A.
Power cord is not plugged in or circuit
breaker is tripped.
A.
Plug power cord in and verify that
the circuit breaker is not tripped.
B.
Controller has failed.
B.
If available, substitute a controller
known to be working for the
suspect controller. If the substitute
controller functions correctly, order
a new controller from a FASC.
Controller won't
activate.
C.
Power supply component or
temperature control board has failed.
C.
If any of the components in the
power supply system (including the
transformer and temperature control
board) fail, power will not be
supplied to the controller and it will
not function.
Fryer does not heat.
A.
Controller has failed.
A.
If available, substitute a controller
known to be working for the
suspect controller. If the substitute
controller functions correctly, order
