ens. By starting large loads with 5 to 8 minutes
of steam you help the oven recover and cut the
cooking time by more than 10%.
Bake bagels without boiling. By starting raw ba
gels with 1 to 2 minutes of steam you can
achieve a beautiful crust.
Cream caramel is great at 230_F to 250_F in the
Combi mode using 2 minutes of on demand
steam.
When cooking chicken wings, try setting the
oven in the Combi mode at 375_F and use 3
minutes of Steam On Demand. This method will
stop the tips from burning. Total cooking time is
approximately 12 minutes.
Pork ribs tend to pull off the bone better when
using 5 to 8 minutes of Steam On Demand. Try

BCX14G TROUBLESHOOTING GUIDE
6. Acv/Dcv. See the incoming power supply flow
chart (FIGURE 1).
In this troubleshooting guide, the schematic is
broken down into areas. This allows the oven to be
checked in sections.
NO OPERATION WITH THE MODE SWITCH
IN COOL DOWN
When troubleshooting, tilt the control panel down
for access to use your voltmeter. The main control
circuit voltage for all BX / BCX and CNVX model
ovens is 24DC volts.
Once the problem is
determined be sure to power the oven down before
disconnecting connections.
1. Verify that the control panel circuit breaker is in
the on position.
2. Check the outlet for proper power supply.
3. Remove the LH body side panel and inspect the
motor inverter control to see if it is powered up
with 115Acv and if there are any error codes
present if so, see the attached fault code list for
troubleshooting. The display will show 00 if
there are no fault codes present while the motor
is not running. If no codes are present continue
or if a code is present see the programming fault
code troubleshooting flow chart in section 4
(FIGURE 1) page 15.
4. Locate the logic board small vertical RH
connector J1 using your voltmeter checking for
24Dcv between (J1-4) to the mode switch
terminal # 4 voltage should be present, if not
investigate the mode switch.
Also check
between the J1 connector (J1-4) to the inverter
connector BK-12 wire at CM2 for 24Dcv, if no
voltage check the IFB relay board connector J3.
5. To bypass the mode switch and wire harness
use your voltmeter set to the 10amp red fuse
side with the black in COM then set your meter
to DC amps, now your meter is a fused jumper
wire. Now jump between the logic board J1
connector (J1-1) to the motor speed inverter
GY-19 low signal at terminal # 2 of the inverter.
This should activate the inverter power up. See
the cool down operation troubleshooting flow
chart (FIGURE 3).
NOTE: Always troubleshoot Combi ovens in the
following sequence: COOL DOWN, HOT AIR,
STEAM and then COMBI. Reference the text that
follows with the appropriate troubleshooting
schematic to help you troubleshoot each mode.
DC VOLTAGE TEST POINTS
1. At the DCV power supply should be (2)
+24Dcv and (2) -24Dcv_Rtn connections, when
115Acv is applied to the power supply there
will be a small green light on at the power
supply and it should always have 24Dcv
between the plus and minus points.
2. Locate the logic board small connector J1 using
your voltmeter checking for 24Dcv between
terminals (J1-1) 24Dcv Rtn to (J1-4) +24Dcv to
verify true 24Dcv input to enable the logic
board during the power up.
3. The J1 connector between (J1-1) -24Dcv Rtn
and (J1-4) +24dcv will be the best (Test points).
When troubleshooting any problems, if your
looking for a low signal test between (J1-4)
+24Dcv RD to the low input searching for, or if
your looking for a +24Dcv_H positive leg of
power check between (J1-1) -24Dcv_Rtn and
the high signal searching for. (See FIGURE 1)
4. Checking for 24Dcv at the IFB relay board J7
connector between (J7-1) to (J7-2).
5. NOTE: While troubleshooting the 24Dcv circuit
with the wire schematic you will see that most
all of the control switching is to a (Low)
24Dcv_Rtn. Also while reviewing the wire
schematic you will see the wires labeled as a
(High) or (Low) input such as (Oven_On_L) for
the low input and (Door_Closed_H) for a high
input/output.

DRAIN VALVE TROUBLESHOOTING AND
OPERATION
5.
1. The drain valve will always remain in the
closed position during all mode operations.
2. If the oven boiler is below 150 degrees and
after somewhere between 3-5 hours of non use
the logic board will activate the drain valve
motor to open and drain the boiler down then it
will close the drain valve motor and then refill
the boiler to the low level float switch.
3. When troubleshooting the drain valve motor
operation there is a small stem switch on the
right side of the IFB relay board. This can be
depressed to activate the drain valve motor,
while holding the switch (In) the drain valve
motor open fully to drain the boiler down and
when the switch is released the drain valve
motor will return to the normally closed

If no voltage is found during the first test at the
delime pump, go to the IFB relay board J8
connector and test between (J8-1) to (J8-2)
24Vdc should be present.
Continued testing, check for 24Vdc to the R-12
wire at the delime pump testing from the J8
IFB connector (J8-2) to the R-12 wire. If
voltage is good this would mean the red
+24Vdc is good now check between the V-13
wire at the delime pump to check the
24Vdc_Rtn_L input from the J8 connector test
between (J8-1) to V-13. If no voltage inspect
the IFB relay board for damage.
MOTOR SPEED INVERTER PRGRAMING
1. Every motor speed inverter has been
programmed from the factory however for
some reason if it lost it’s programming it can
be reprogrammed manually.
2. You will see on the inverter drive the green

Drain_Open_H
The drain valve in its normally
closed position should always
have 24Dcv_Rtn_L input along
with the +24Dcv_H out put
from the IFB J8 connector to
the motorized drain valve.
The drain valve opens when the
+24Dcv_H switches from J8-8
to J8-9 then it should switch
back to close.
BK-20
The drain valve will only open
when the logic board sends an
output signal to the IFB after
oven is cold and 4-5 hours of
non use, or when the flush
switch is activated at the IFB.
