ELECTRIC COMBI OVEN - ELECTRICAL OPERATION
Contactor for steam generator heating elements; (7HTR) on 20 level half
and (8HTR) on 20 level full only.
Contactor for convection heating elements; (1HTR) on 6 level; (1HTR)
inner on 10 level; (1HTR) Inner top and (5HTR) inner bottom on 20 level.
Contactor for convection heating elements; (3HTR) outer on 10 level;
(3HTR) outer top and (6HTR) outer bottom on 20 level.
Single convection heating elements on 6 level; Inner on 10 level and 20
level (top).
Steam generator heating elements on 6, 10 and 20 level.
Outer convection heating elements on 10 level and 20 level (top).
Steam generator heating elements on 10 and 20 level.
Inner convection heating elements on 20 level (bottom).
Outer convection heating elements on 20 level (bottom).
Steam generator heating elements on 20 level 1/2 size.

Controls power to door motor(s).
Controls power to cavity vent motor.
Controls power to component cooling fan(s) and supplies power to one
side of K4, K5, and K6, K7, K8, K9 and K10 through the thermal fuses
and high limit thermostats.
Controls power to water injection solenoid valve (humidifier) and door
light when K3 is ON.
Controls power to water fill solenoid valve (when K3 is ON) and drain
pump motor (when K3 is OFF).
Controls power to contactor KM1. This relay is energized along with K7
for full power full speed operation, and is also energized in half power
speed half mode. When half power half speed mode is selected, relay K6
is energized.
Controls power to contactor KM2. This relay is energized along with K6
for full power full speed operation. When half power half speed mode is
selected, relay K7 is not energized. On 20 level models only, controls
power to contactor KM3 for steam generator heating elements, and
powers 2SOL drain cool down solenoid.
Controls power to KM3 for steam generator heating elements, and
powers 2SOL drain cool down solenoid valve on 6 & 10 levels. On 20
level models only, controls power to contactor KM5.
Controls power to KM6 for convection heating elements; (1HTR) single
on 6 level ;(1HTR) inner on 10 level; (1HTR) inner top and (5HTR) inner
bottom on 20 level.
Controls power to KM7 for convection heating elements ; (3HTR) outer
on 10 level; (3HTR) outer top and (6HTR) outer bottom on 20 level.
