Fault codes are listed in order of hierarchy. For example, if during cooking the oven experiences an F1
and F2 fault, the o
ven will report only the F1 fault because the software will halt all actions upon
disco
vering the F1 fault.
Fault codes F1 - F5 and F7 will terminate a cook cycle upon discovery.
F7: RTD Open
This fault is display
ed when the control detects
that the R
TD is “
open.” The display will show a
reading of “999
º
F/C,” indicating the RTD is open.
The fault is clear
ed when the contr
ol detects
continuity.
F8: Heat Low
This fault displays when the o
ven 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 ex
cessiv
e 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 cy
cle upon discovery.
