BCX14E TROUBLESHOOTING GUIDE

In this troubleshooting guide, the schematic is
broken down into areas. This allows the oven to be
checked in sections.

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.

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
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.

to (J1-4) +24Dcv to

6. Acv/Dcv. See the incoming power supply flow
chart (FIGURE 1).

NO OPERATION WITH THE MODE SWITCH
IN COOL DOWN

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 section 4
(FIGURE 1) page 9-1.

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).

NO OPERATION WITH THE MODE SWITCH
IN HOT AIR

1. Verify that the convection motor is running with
the door fully closed. If not see door switch

6. If all of the above are good continue testing
checking at the lower of the two Dcv 24V
power supplies for a lighted small green light
along with checking for 24Dcv output.

7. Next go directly the (K1) hot air contactor and
measure the coil voltage between A1 & A2 for
24dcv volts, if not check A1 at the coil to the J1
connector at the logic board J1-1 for 24dcv and
if okay check A2 coil to logic board J1-4 for
24dcv.

8. In either case no voltage go the IFB relay board
and check for 24dcv at J4 connector between
J4-1 and J4-2 for 24dcv from the power supply,
good check from J4-6 to logic board J1-1 for
24dcv output to the contactor coil.

3. Remove the LH body side panel and tilt the
control panel down for troubleshooting access.

4. Check for logic board input/output LED
indicators, in the steam mode the amber input
LED’s # 3 and # 6 need to be on along with the
green output LED # 10. Verify LED’S with the
LED designation flow chart (FIGURE 11).

5. Look for LED indicator inputs present at the
IFB relay board, looking for the CR3 relay
LED (D31), CR2 relay LED (D21) and the

6. CR7 relay LED (D71) should be on. If not

check IFB connector J7 between (J7-1) to (J7-

2) 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
checking at the lower of the two power
supplies for a lighted small green light along
with checking for 24dcv output.

9. Next go directly the (K2) steam contactor and
measure the coil voltage between A1 & A2 for
24dcv volts, if not check A1 at the coil to the J1
connector at the logic board J1-1 for 24dcv and
if okay check A2 coil to logic board J1-4 for
24dcv.

10. In either case no voltage go the IFB relay board
and check for 24dcv at J6 connector between
J6-1 and J6-2 for 24dcv from the power supply,
good check from J6-5 to logic board J1-1 for
24dcv output to the contactor coil.

NO OPERATION WITH THE MODE
SWITCH IN COMBI

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 is 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 Combi mode the amber input
LED’s #2 and #6 need to be on along with the
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 #50277
between (J7-1) to (J7-2). Verify the LED inputs
with the IFB LED indicator designation flow
chart (FIGURE 12).

8. If all of the above is good continue testing
checking at the lower of the two power supplies
for a lighted small green light along with
checking for 24dcv output.

9. Next go directly the (K1) hot air contactor and
measure the coil voltage between A1 & A2 for
24dcv volts, if not check A1 at the coil to the J1
connector at the logic board J1-1 for 24dcv and
if okay check A2 coil to logic board J1-4 for
24dcv.

10. Hot air contactor will mostly control the Combi
mode along with the logic board switching
from hot air contactor to steam contactor for on
and off for about 45 seconds as long as the
boiler has come above the preheat temp of 180°
already.

11. In either case no voltage go the IFB relay board
and check for 24dcv at J4 connector between
J4-1 and J4-2 for 24dcv from the power supply,
good check from J4-6 to logic board J1-1 for
24dcv output to the contactor coil.

NO FILLING OF THE STEAM BOILER

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 flow 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.

8. See the float switch troubleshooting flow chart
(FIGURE 8).

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
would indicate the (LLC) low level cut float is
in the closed position and will not open. Repair
or replace floats switch as needed.

3. Check both float switches for normally closed
when empty and open when steam generator is
full. (If they do not open repair or replace floats
as needed.

4. See the float switch troubleshooting flow chart
(FIGURE 8).

CONVECTION MOTOR WILL NOT
REVERSE DIRECTIONS.

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).

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

B l o d g e t t O v e n

Page 21

BCX14E

BCX14E TROUBLESHOOTING GUIDE

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
been activated and the blower motor should
began running.

6. At this point check for +24Vdc_H output from
the IFB connector J5 from (J5-2) to (J5-5). If
the voltage is present and the door switch is
closed now look for an LED indicator at the
IFB relay board CR2 relay (D21). See door
switch troubleshooting flow chart (FIGURE 7).

DRAIN VALVE TROUBLESHOOTING AND
OPERATION

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).

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).

NO DELIME PUMP OPERATION

1. The delime pump can be tested with the oven
placed in the cool down, when you press and
hold the steam on demand button for a few
several seconds 24Vdc should be applied
directly the delime pump.

2. Verify when you activate the steam on demand
button, at the logic board LED indicators
amber input #4 and green output #12 light up.

3. 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.

4. Continued testing, check for 24Vdc to the R-12
wire at the delime pump testing from the J8

5. 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).

Relay Board

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

BK-20

to J8-9 then it should switch
back to close.

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.

Lit Sheet Combi LED (BP# 53024) Light Replacement

1. Remove the light/bracket assembly by removing two nuts as shown in Fig. 1

2. Remove light from bracket

3. Place the new LED light (BP 53024) in existing bracke

t and install on existing studs.

Secure with the two nuts that were removed in step 1.

4. Wire up the new LED light. The LED light is polarity dependent and therefore it must be
wired properly according to the following direction. :

A. If the pair of wires going to the light has a red wire, plug the red wire on the tab #1

(numbering located on side of LED light) which is also marked with a red line. Then
plug the remaining wire on the negative tab # 6.

B. If the pair of wires going to the light has a black wire, plug the black wire on the

negative tab # 6 (numbering located on side of LED light). Then plug the remaining
wire on the positive tab # 1, which is the tab marked with a red line.

Remove two nuts to remove

light/bracket assembly

Note: If not wired properly the LED light will not illuminate

BCX14E Element Drip Deflector Kit: 53550

This kit will create a barrier between the boiler elements and the electrical components in the chance
that an element gasket fails.

Kit Includes:

1. Disconnect power to the oven.

2. Remove the Left Side panel. If a Manual Control oven, remove the two nuts used to hold the

thermal snap disc. See Figure 1. (MenuSelect Control ovens do not use the snap disc.)

3. If a Manual Control oven, remove the thermal snap disc from the boiler. Discard the small

bracket. The new drip pan will retain the snap disc.

4. Replace the machine screws that hold the boiler down with the low-profile machine screws

provided. Use the nuts that were on the original machine screws to bolt the boiler down (Figure

2).

Figure 5

Figure 6

Figure 7

5. Attach the Drip Deflector box to the boiler using the flanged head nuts supplied. If a Manual

Control oven, reattach the thermal snap disc under the Drip Deflector. Tighten the Drip
Deflector to the boiler assuring the gasket creates a seal between the boiler and Drip Deflector.

6. Attach the silicone tubing supplied to the bottom side of the Drip Deflector. See Figure 4.

7. Route the tubing towards the back of the oven as shown in Figure 5.

L-949

Rev: A

8. Attach tubing to side using the cushion clamps provided.

9. Remove back panel piece that holds cooling fan. You may have to disconnect the deliming tube

connection and fan terminals.

10. Remove the black plug above the incoming power line on the exterior of oven. Replace with the

liquid tight connector provided in kit.

11. Lubricate the silicone tubing (with pipe) on the exterior. This will make it simpler to slide tubing

into liquid tight connector. Ensure that the silicone tubing is flush with end of connector. Once
installed tighten the connector.

12. Reattach back panel piece.

13. Reattach Left side body panel.

14. Connect power to oven.
