BCX14G 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 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).
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 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.
