THEORY OF OPERATION
ELECTRONIC OPERATION
The components that control the electronic op-
eration of this range include the following:
Thermostat & Selector Switch Assembly
Electronic Control
(Secondary Board)
Main Electronic
Control
The two thermostat & selector switch assem-
blies are mounted on the front manifold panel,
and function the same as a touch pad on a
microwave oven.
Each oven has its own components, with the
exception of the main electronic control. The
main electronic control is used to synchronize
the two secondary boards for the displayed
“Time of Day.” It also monitors the secondary
boards to prevent two self-clean functions from
occurring at the same time. In addition, it pre-
vents a self-clean and cooking function from
occurring at the same time.
The main control is supplied with 24 VAC from
the control board power transformer. It com-
municates between the secondary oven elec-
tronic controls with 5 volt pulses from the main
control’s P9-1 yellow wire, and uses the P9-3
orange wire as a ground reference. If the main
control malfunctions, an
F04
error code will be
indicated in the clock displays. Refer to the
Tech Sheet that is supplied with the unit for
additional information.
As you turn a selector switch to a particular
setting, (i.e. Bake, Broil, Clean, etc.), individual
relays on the oven’s electronic control close,
and the appropriate circuits are completed.
