Introduction Fault Code Introduction:
The C3C oven has the ability to continually
monitor and log various fault conditions. Some
fault conditions will terminate cook cycles, while
others will not. Please refer to Table 4-1 for fault
codes:
The Codes are listed in order of hierarchy. 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.
In addition if a fault is detected the fault counter
will increment. If the fault is cleared the fault
counter will not de-increment.

To view the Fault Log, press the “4” and “6” keys
simultaneously in the Off State. The oven will
display all logged faults. See Figure 4-1.
Each Fault Register will log up 255 instances
before rolling back to zero. The Cook Count will
log up to 65,535 Cook Cycles. Note: In order
for the Control to log a Cook Cycle, the oven
must complete the 1
st
Event of any given recipe.
If a Recipe only has 1 Event, the oven must
complete the entire Cook Cycle in order to count
the Cook Cycle.
Note: To reset Fault Counter, Press the “0” key.
LOW MAG CURR (HV BREAKDOWN) or F3
MAG CURR – the magnetron transformer is
drawing less than 7 amps. The normal current
draw is approximately 9 amps. The current draw
is being monitored by the control board which
has a current transformer mounted on it. See
section 6
LOW COOK TEMP or F2 LOW TEMP– the
temperature set for the C3 SERIES is not being
maintained within 84
o
F (46
o
C) differential of the
Cook Chamber Setpoint. It is referenced by the
cook chamber type K thermocouple. Note: It
may also be controlled by the heat exchanger
thermocouple. See section 5
MAG OVER TMP or F5 MAG TEMP– the snap
disk on the magnetron has overheated and has
tripped. Reference Chpt. 9
BLOWER STATUS or F1 BLOWER – The
control board is not receiving the proper output
from the convection (blower) motor speed
control. Reference Chpt. 8
ELEC OVR TMP (EC TMP HIGH) or F6 EC
TEMP – The electronics compartment
thermocouple connected to the control board has
detected a temperature above 140ºF (60ºC).
Reference Chpt. 6
OVEN DOOR OPEN – (during cook cycle) the
cooking door has been opened during a cook
cycle and has not been closed properly.
DOOR MONITOR or F4 MONITOR: -- The
control board senses that the Cook Door
Monitor Switch is out-of-sequence with the
Primary and/or Secondary Door Switches.
Reference Chpt. 7
HX RISE LOW - HX (Heater) Temperature has
failed to rise 14ºF (~8ºC) F in 30 seconds.

no longer available or current. The following
