Fault Code Table - TurboChef NGC (Tornado) Service Manual

10 FAULT CODES
   : Door Interlock Switches are in parallel. See
Figure 35, on the inside of page 49. The fault is
monitored during a Cook Cycle or Self-Test, when
the Microwave is on.
F5: Magnetron Over Temperature
Fault is displayed when the Thermostat on either
Magnetron is "Open".
The fault is cleared at the onset of a Cook Cycle if
the Thermostat is closed or when the Magnetron is
successfully tested in the Test Mode.
F6: EC (Electrical Compartment) Temperature High
Fault is displayed when the EC Thermocouple
exceeds 158 º F and is monitored once per minute.
The fault is cleared when the EC Thermocouples
temperature is below the indicated limit.

FAULT CODE TABLE

FAULT CODE AND DESCRIPTION
F1: Blower Running Status Bad
F2: Cook Temperature Low
F3: Magnetron Current Low
F4: Door Monitor Defective
F5: Magnetron Over Temperature
F6: EC Temperature High
F7: Thermocouple Open
F8: Heat Low
Fault Codes are listed in order of hierarchy. For example: If during cooking the oven experiences an F1
and F2 Fault, the oven will only report a F1 Fault since the software will halt all actions upon discovering
the F1 Fault. F7 and F8 Faults are displayed on the primary screen and are not displayed or counted in
the Fault Log.
   : All Fault Codes listed in Bold will terminate a Cook Cycle upon discovery. Any fault occurring
in a Cook Cycle will be logged in the Fault Code Counter.
F7: Thermocouple Open
Fault is displayed when the Control detects that
either the IR or CC Thermocouple is "Open".
999 º F indicates the CC Thermocouple is "Open".
1999 º F indicates the IR Thermocouple is "Open".
Fault is cleared when the control detects continuity
on the open Thermocouple Circuit.
F8: Heat Low
An Error Message (not a Fault Code) displayed
during Warm-up or Self-Test if the Cook Chamber
Temperature (TCC) fails to rise 14 º F within thirty
(30) seconds.
