COMPONENT IDENTIFICATION
The following is a key for the abbreviations of com-
ponents on the schematic. Additional information
is provided as to the function of the component to
assist you in troubleshooting.
NOTE: Refer to the figures on pages 6 ---5 and
6 ---6 for component locations.
1. CF1 --- Electrical compartment cooling fan.
2. CH-136 – optional COOK & HOLD control for
oven operation. Controller has two LCD dis-
plays and soft -key push button control
3. CW --- s t a n d s f o r C O L D W AT E R o n l y.
4. (ELECTRIC OVENS) -- Elements (Hot Air) ---
quantity (10), 1.5KW elements located in the
cook Compartment.
5. (ELECTRIC OVENS) -- Elements (Steam) ---
quantity (6), 3. 0KW elements located in the
steam generator. Elements are in an assembly
with 2 elements per assembly.
6. Flush/Fill (solenoid) --- ( no designation)indi-
cates non-restricted solenoid used for fast fill-
ing and flushing of the steam generator.
7. (GAS OVENS) -- F1 & F2 – 12. 5 amp control
fuses
8. (ELECTRIC OVENS) -- F1 & F2 –5ampslow
blow control fuses
9. F3 --- Cooking Compartment High Limit Ther-
mostat. Capillary type thermostat with the
sensing bulb located in the cooking compart-
ment. Opens at 662_F or 350_Cdisablingthe
control circuit.
10. (ELECTRIC OVENS) -- F3-5A –(5ampfuse
on secondary of step down transformer of
480v electric Synergy ovens
11. (ELECTRIC OVENS) -- F3-60A, F4-60A,
F5-60A, & F6-60A – 60amp fusing for the Hot
Air & Steam elements in a BC14E Synergy
Electric single-phase oven
12. F6 – Boiler High Limit thermostat. Capillary,
manual reset, steam generator high limit.
Opens at 257_F or 125_C.
13. F9 – 350ma meat probe fuse
14. (GAS OVENS) -- Hot Air IGN1, IGN2 –HotAir
Ignition Control Modual. Sequence of opera-
tion: Input 24Vac to THS2 & GND. SPARK out-
puts to pilot a ssembly and sparks. PV1 out-
puts to pilot valve & opens valve. SPARK
output continues until flame sense is proved
(.15 microamps is lockout / minimum you
should see is .2 ). Lock out of modual is after
50 seconds if flame sense has not been
proved. Once SENSE4 has proved, MV3 out-
puts. MV3 is connected to IGN2 modual, termi-
nal THS2. Ignition sequence continues for 2nd
modual. MV3 supplies power to main valve on
the combination valve. Burners light.
15. Hot Water Fill (sol enoid) –(no designation)
The solenoid used for slow filling (fill line is re-
stricted) the steam generator with water by the
HLC reed float assembly.
16. H2 – Low Water light. Low water light on the
low er right hand corner of the control panel. It
is only on when the Low Level Control (LLC)
float s witch is closed (steam generator is fast
filling).
17. H4 – Power “On” light. indicates the oven has
been turn on in the “STEAM”, HOTAIR”, or
“COMBI” mode.
18. H5 – duty light for temperature control board.
19. H6 – Steam Duty light. When lit, indicates pow-
er is being supplied to the steam ignition cir-
cuit.
20. HLC – High L evel Control . Fl oat switch (reed
switch) in the float assembly which does the nor-
mal operatio n water fi ll to the steam generator
(this is the shorter float in the float assembly)
21. (ELECTRIC OVENS) -- K2 (A & B Primary) –
Solid State Hot Air Relays (SSRs). (2) 45 amp
solid state relays for hot air. K2A is deactivated
in Combi mode if Steam circuit is calling for
heat.
22. (ELECTRIC OVENS) -- K3 (A & B Primary) –
Solid State Steam Relays (SSRs) (2) 45 amp
solid state relays for steam. K2A is deactivated
in Combi mode if the thermostat is calling for
heat.
23. LLC – Low Level Control. Float switch (reed
switch) in the float assembly w hich fast fills the
steam generator (this is the longer float in the
float assembly).
