F5: Magnetron Over Temperature
Fault is displayed when either magnetron thermo-

The fault is cleared from the display at the onset of
a cook cycle if the thermostat is closed or when the

F6: EC (Electrical Compartment) Temperature High
Fault is displayed when the EC thermocouple
exceeds 158 º F (70 º C). It is monitored once per
minute.

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 report only the F1 fault because the software will halt all actions upon discov-
ering the F1 fault. F7 and F8 faults are displayed on the primary screen and are not displayed or counted
in the Fault Log.

Fault does not log in counter. Fault is displayed
when the control detects that either the IR or CC
thermocouple is "open."
999 º F/C indicates CC thermocouple is "open."
