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
discovering the F1 fault.
Fault codes F1 - F5 and F7 will terminate a cook cycle upon discovery.
F7: RTD Open
This fault is displayed when the control detects
that the RTD is “open.” The display will show a
reading of “999
º
F/C,” indicating the RTD is open.
The fault is cleared when the control detects
continuity.
F8: Heat Low
This fault displays during
WARMING UP or TEST
MODE
if the cook cavity temperature fails to rise at
least 14
º
F (7
º
C) within a given 30 seconds.
