When the unit is plugged in and line voltage is
applied to the electronic oven control, the
following keyboard actions are used to set the
oven CLEAN function:
• The CLEAN function is selected.
• The desired cleaning time is selected.
When the preceding events occur, the BAKE
relay energizes, and its contacts close. This
provides an electrical circuit through the BAKE
ignitor and the BAKE valve to the neutral side
of the line.

Because the oven reaches extremely hot tem-
peratures, the oven door is latched during the
CLEAN cycle, and remains latched until the
oven has cooled to a safe temperature.
The door latching operation occurs when the
LATCH SOLENOID relay closes, and electri-
cal current flows through the LATCH SOLE-
NOID.
After the CLEAN cycle has been completed,
the door latch will release when the oven
temperature drops below 400˚F.
