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: E
C (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.
F7: Thermocouple Open
Fault is displayed when the Control detects that
either the IR or CC Thermocouple is “Open”.
o
999
º
F indicates the CC Thermocouple is “Open”.
o
1999
º
F indicates the IR Thermocouple is “Open”.
Fault is cleared when the control detects continuity
on the open Thermocouple Circuit.
F8: Heat Lo

An Error Message (not a Fault Code) displayed
during Warm-up or Self-Test if the Cook Chamber

. 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 F
aults ar

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.
