BC14E TROUBLESHOOTING GUIDE
In the following troubleshooting guide, the sche-
maticisbrokendownintoareas.Thisallowsthe
oven to be checked in sections.
When troubleshooting, slide the control panel out
and use your volt meter. The main control circuit
voltage for all Synergy ovens is 230 volts. Once the
problem is determined, it is often easier to remove
the slide out from the oven completely to change
components. To remove the slide out, disconnect
the hot air thermostat probe, ground w ire, and
large brown plug in connector.
NOTE: Always troubleshoot a Synergy oven in the
following sequence: COOL DOWN, HOT
AIR, STEAM, and then COMBI. Reference
the text that follows with the appropriate
sch e mat ic to help trouble sh o ot ea c h mode.
NO OPERATION WITH THE MODE SWITCH IN
COOL DOWN
1. V eri fy the deliming switch is in the on position.
2. Verify the water to the oven is turned on.
3. Verify power is being supplied at the outlet.
4. Check t he fuses in the panel underneath the
control panel. See FIGURE 1, location (A).
5. Single phase ovens --- R em o ve t h e fr o nt d ri p
pan and check the 60 amp fuses located under
theoven.SeeFIGURE1,location(A).
6. Check the noise filter input and output. See
FIGURE 1, location (A).
7. Check the P13 snap disk. See FIGURE 1, loca-
tion (B).
8. Check the mode switch. See FIGURE 1.
9. Check t he fan speed switch. See FIGURE 1,
location (G).
10. If the motor works in high speed and not low ,
check the solid state speed control . See
FIGURE 1, location (I).
11. Check the motor. See FIGURE 1, location (J).
NO OPERATION WITH THE MODE SWITCH IN
HOT AIR
1. Check power at terminal 12 on the mode
switch. See FIGURE 1, location (H). If there is
no power, continue. If the power is 208V, pro-
ceed to STEP 8. See FIGURE 2, location (B).
2. Check the F3 oven high limit. See FIGURE 1,
location (B).
3. Check the mode switch. See FIGURE 1.
4. Check the S2 door switch. See FIGURE 1,
location (D).
5. Check relay R5. See FIGURE 1, location (E).
6. Check t imer S5. Turn timer to ten minutes and
continue. See FIGURE 1, location (E).
7. Check the mode switch. See FIGURE 1, loca -
tion (H).
8. Check R202 relay. See FIGURE 2, location (B).
9. If the hot air light is not lit on P5, check the P5
temp controller for voltage. See FIGURE 2
location (B).
10. Check that relay R205 contacts 9 a nd 1 a re
closed. See FIGURE 2, location (C).
11. Check R201 relay contacts. See FIGURE 2,
location (E).
12. Check solid state contactor K2-A, is the red
LED on? See FIGURE 2, location (F).
13. Check R200 relay, coil and contacts. See
FIGURE 2, location (D).
14. Check solid state contactor K2-B, is red LED
on? See FIGURE 2, location (F).
NO OPERATION WITH THE MODE SWITCH IN
STEAM
1. Check power at terminal 6 on the mode switch.
SeeFIGURE1,location(H).Ifthereisnopow-
er, return to NO OPERATION WITH THE MODE
SWITCH IN HOT AIR.Yourproblemismostlike-
ly a ba d mode switch position. I f p ower is 230V
proceed.
2. If the steam lo go by the mode switch is ill umi-
nated, jump to STEP 9.
3. If the LOW WATER light in the lower right hand
corner of the control panel stays on, jump to
NO FILLING OF STEAM GENERATOR.
4. Check that R202 relay contacts close. See
FIGURE 3, location (B).
5. If the hot air light is not lit (H5) on P5, check P5
temp controller for voltage. See FIGURE 3,
location (B).
