Repair manual
COMPONENT IDENTIFICATION
6 --- 2
24. M – Convection motor. 1/2 hp , 208V / 115V
convection motor. Has a n internal self-reset-
ting thermal overload at 250_F.
25. Meat Probe (no designation)–“J”typether-
mocouple meat probe which plugs into front of
the oven.
26. Meat Probe Controller (optional) – shuts off
the oven and sounds the buzzer when set tem-
perature has been reached.
27. (ELECTRIC OVENS) -- Noise Filter –noisefil-
ter in control circuit.
28. Pump --- pump used for removing water from
the steam generator when deliming and when
self-flushing.
29. (GAS OVENS) --PV,PV1,PV2–pilotvalves.
PV is the pilot valve on the main combination
valv e used for steam. PV1 is the single coil pil o t
valve used for hot air. PV2 is the pilot valve on the
main combination gas valve used for hot air.
30. P4 – Quench snap-disk. Snap -disk located
neartherearofthedrainpipetosupplypower
to the quench solenoid. Closes at 167_For
75_C. Opens at 140_For60_C.
31. P5 – Temperature Control Board. Power in is
on terminals C & L1. Terminals COM & NO
close until desired set temperature is reached
in all modes of operation.
32. P11 – Flush Disable snap -disk. Snap-disk lo-
cated on the steam generator used to energize
the T4 Flush Solid State Timer. Closes at 160_F
or 71_C. Opens at 180_For82_C.
33. (ELECTRIC OVENS) -- P12 – Cold Plate Water
Flow Snap Disk snap disk located on the Solid
State Relay Cold Plate assembly, opens at
95_For35_C.Closes at 122_For50_C. Pro-
vides normal cooling of cold plate assembly.
34. (ELECTRIC OVENS) -- P13 –ColdPlateNO
water Fail-safe Snap Disk snap disk located on
the Solid State Relay Cold Plate assembly,
opens a t 176_For80_C and shuts down the
oven / closes at 149_For65_C.
35. (GAS OVENS) -- Quench --- C o l d w a t e r d r a i n
quench solenoid. Coil resistance is approxi-
mately 1830 ohms.
36. (ELECTRIC OVENS) -- Quench --- C o l d w a t e r
drain quench solenoid. Coil resistance is
approximately 1830 ohms. Water supply also
for the SSR cold plate assembly.
37. Resister (designated as “5.6Ka”) -- Resister in
series with the buzzer to drop voltage to the
buzzer to allow for long periods of operation.
38. R5 – Meat probe relay
D
Coil is terminals 1 & 5. Coil is energized by
the meat probe control terminal 6.
D
Coil energized. Terminals 4 to 3 close, en-
ergizing the buzzer.
D
Coil not energized. Terminals 4 to 2 closed,
power to timer, S5, terminal 4.
39. (ELECTRIC OVENS) -- R200 –HotAirRelay
coil is terminals 13 & 14 / coil is energiized
when oven is in “Hot Air” or “Combi” and P5
thermostat is calling for heat. Terminals 10 to
6 close, energizing K2-B.
40. (ELECTRIC OVENS) --- R201 – Load Splitting
Relay
D
Coil is terminals 13 &14. Coil is energized
by R204 terminal 1 w hen s teamgenerator
is full
D
Coil energized. Terminals 9 to 5 close,
power is supplied t o F6, then the s team
contactors. Terminals 10 to 2 open, no
power to K2-A Hot Air contactor.
D
coil not energized. Terminals 9 to 5 are
open, no power to F6 (no power to steam
contactors). Terminals 10 to 2 are closed,
supplies power to K2-A Hot Air contactor.
41. (GAS OVENS) -- R202 – On demand steam
relay
D
Coil is terminals 13 & 14. Coil is energized
by One shot Steam timer, T3 terminal 2.
D
Coil energized terminals 9 to 5 close. This
by-passes the temperature thermostat
and provides power to F6 Boiler High Limit
thermostat.
D
Coil not energized terminals 9 to 1 closed,
normal operation, provides power to F6
Boiler High limit thermostat.
