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 when the oven is warming up or
during Test Mode if the cook cavity temperature
fails to rise at least 14
º
F (7
º
C) within a given 30
seconds.
F9: Cook Cavity Temperature High
This fault will signal that the catalyst has “flashed”
due to excessive grease. The fault occurs when the
RTD senses +650°F (343°C) for more than 40
seconds but less than 2 minutes. The fault will only
appear in the fault log and will not terminate a cook
cycle upon discovery.
F10: Communication Failure (Touch Enabled
Ovens Only)
This fault will signal that the UI control board
(Phoenix) is no longer able to communicate with
the I/O control board (SAGE). This fault will ter-
minate a cook cycle upon discovery.

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, F7, F10, AND F12 WILL TERMINATE A COOK CYCLE UPON DISCOVERY.
