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.
IN HOT AIR
1. Verify that the convection motor is running with
the door fully closed. If not see door switch
troubleshooting flow chart (FIGURE 7).
2. Verify that the thermostat has powered up,
counted down and displaying a set temperature
along with the heat indicator light activated.
3. Remove the LH body side panel and tilt the
control panel down for troubleshooting access.

4. Checking for logic board input/output LED
indicators, in the hot air mode the amber input
LED’s #6 and #9 need to be on along with the
green output LED #13. Verify LED’S with the
logic board LED designation flow chart
(FIGURE 11).
5. Also look for LED indicator inputs at the (IFB)
relay board, the CR3 relay LED (D31), CR2
relay LED (D21) and the CR1 relay LED (D11)
will all need to be on. If not check all
connectors and the 24Dcv inputs at the J7
connector per the wire schematic. Verify
LED’S with the IFB LED indicator designation
flow chart (FIGURE 12).
6. If all of the above are good continue testing
checking at the (T1) transformer for 24Acv
output if good check the IFB connector J4
between (J4-1) and (J4-2) 24Acv should be
present.
7. Check for burner pilots if none check between
the J4 connector (J4-2) to (J4-3) for 24Acv.
8. If pilots were on but no main burner check the
J4 connector between (J4-2) to (J4-4) for
24Acv. If not then check the (IFB J4) connector
for damage).
9. See the Hot air troubleshooting flow chart
(FIGURE 4).
6. CR7 relay LED (D71) should be on. If not
check IFB connector J7 between (J7-1) to (J72) for 24Dcv input see wire schematic. Verify
LED’S with the IFB LED indicator flow chart
(FIGURE 12).
7. If all of the above is good continue testing
8. Output if good check the IFB connector J6
between (J6-1) to (J6-2) 24Acv should be
present.
9. Check for the steam burner pilot if none check
the J6 connector between (J6-2 to (J6-3) for
24Acv.
10. If pilot was on but no main burner check the J6
connector between (J6-2) to (J6-4) for 24Acv.
If not then check the (IFB J6) connector for
possible damage correct as needed). See the
steam mode flow chart (FIGURE 5).

green output LED #13 and then #10 for 45
seconds intervals of steam while in Combi.
Verify LED’S with the LED designation flow
chart (FIGURE 11).
5. Look for LED indicator inputs at the (IFB) relay
board, looking for the CR3 relay LED (D31),
CR2 relay LED (D21), CR1 relay LED (D11)
will all need to be on and CR7 relay LED (D71)
will be on during a 45 second steam on time. If
not check all connectors and the 24Dcv input at
the J7 connector per the wire schematic
between (J7-1) to (J7-2). Verify the LED inputs
with the IFB LED indicator designation flow
chart (FIGURE 12).
IN STEAM
1. Verify that the convection motor is running
with the door closed. If not see door switch
along with the heat indicator light activated.
4. Check for logic board input/output LED

full. (If they do not open repair or replace floats
as needed.
4. See the float switch troubleshooting flow chart
(FIGURE 8).
NO FILLING OF THE STEAM BOILER
1. This oven comes equipped with the feature of
the convection motor reversal after every six
minutes of motor run time in all modes except
for the cool down mode.
2. When any mode but cool down is activated the
motor should start up counter clockwise.
3. Check for 24dcv at the TMR1 timer between
A1 to A2. When verified test between A1 to #
16 for 24dcv after six minutes 24dcv will
switch from terminal #16 to # 18. (If voltage
does not switch remove the wire from #18 and
retest the timer for switching.
4. What ever the out come the motor speed
inverter is looking for a 24Dcv_Rtn_L input
from the timer to either terminal #5 or #6 at the
motor speed inverter to reverse directions.
5. See the motor reverse troubleshooting flow
chart (FIGURE 9).
CONVECTION
MOTOR
REVERSE DIRECTIONS.
1. Verify the water pressure and flow of the water
pressure through the pressure regulator.
2. Verify that the control panel circuit breaker is in
the on position.
3. Check for 24Dcv at the power supply with the
mode switch in the off position, green light ON.
4. Shut the water supply off, then at the IFB board
locate the flush switch in the center RH of the
relay board and press and hold it for 45 seconds
while checking for water flowing out the drain.
5. After doing so disconnect the float wires (mark
as needed) check for continuity, both floats are
normally closed and open when are floats full.
6. If floats are closed re-connect the float wires
and turn the water supply back on. At this point
with the mode switch still in the off position the
logic board LED indicators amber input # 8 and
green output # 15 should be on activating the
fill solenoids.
7. No water filling yet check the IFB fill enable
CR8 relay LED (D81), if not on check the relay
board J8 connector at (J8-1) to (J8-2) for 24dcv.

DOOR SWITCH TROUBLESHOOTING
1. The door switch is a proximity switch that is
activated by the metal of door when it is closed
therefor-proper adjustment is needed.
2. The door switch is located at the lower left
corner with the door open the switch will be
protruding out ½ inch, inspect the switch for
any damage and for proper adjustment.
3. There are three wires from the door switch that
go directly to the IFB connector J5.
4. Check for 24Vdc active at the IFB relay board
at the connector J5 from (J5-3) to (J5-4).
5. If the door switch has 24Vdc going to it when
the door is closed the back of the door switch
will light up to indicate the door switch has
OVER FILLING OF THE STEAM BOILER
1. Turn off the control panel circuit breaker to see
if the water over filling continues in the oven.
2. If water stopped when power was off, turn the
circuit breaker back on and check for the fill
light on the control panel and look at the logic
board for LED indicators. If LED’s amber
input # 8 and green out put # 15 are on this

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
position. (Caution of a hot boiler).
4. See Troubleshooting (FIGURE 10).
several seconds 24Vdc should be applied
directly the delime pump.
Verify when you activate the steam on demand
button, at the logic board LED indicators
amber input #4 and green output #12 light up.
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
(Run) and red (Stop/Reset) buttons, below
those two buttons there is a door that will open
up to gain access to the programming keys
need to reprogram the inverter drive.
3. Behind the access door the programming keys
are (FUNC.), (#1⇑
⇑ ), (#2 ⇓) and (STR).
4. To program the inverter drive back to the
factory settings (See the attached programming
flow chart (Figure 3).
5. See Inverter fault code & stored fault codes
flow chart section 4 (FIGURE 1) page 15.
NO STEAM ON DEMAND
1. While depress the steam on demand button
verify at the logic board LED indicators amber
input # 4 and green output # 12.
2. No LED input check for a 24dcv-Rtn_L input
to the logic board at the J3 connector at (J3-7)
of the logic board. If there is no input
24Dcv_Rtn_L signal go to the steam on
demand switch SW10 and check for a
24Dcv_Rtn_L signal at BK-7 of the switch to
Logic Board J1 connector (J1-4).

+24Dcv should always be
applied to the float wires R-15
that activates the fill solenoid’s
relay at the IFB which applies a
24Dcv_Rtn_L to complete the
power circuit for the water fill
solenoid’s till the float opens.

Drain_Closed_H
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.
