The lock switch circuit signals the control if the
lock motor is in the unlocked or locked position or
somewhere in between. There are 2 lock
switches mounted to and operated by the lock
motor.
The lock switch circuit is from the ERC, through
one of the lock switches (switch 2 for unlocked or
switch 1 for locked) back to the ERC. If neither
switch is closed, and the oven temperature is
below 600°F (315°C) the ERC will energize the
lock motor circuit until the correct switch closes to
complete the circuit. (If circuit to the correct
switch is open, lock motor will run continuously
with the oven below 600°F (315°C).
Clean Cycle and Lock Sequence:
1. Program the Clean Cycle:
•
Press SELF-CLEAN pad. 4 hours (4:00)‚
appears on the time display. (Cleaning
time can be changed from the 4-hour
starting point by pressing the SELF-
CLEAN pad a second time.)
•
After START has been pressed, the word
ON illuminates in red to indicate the cycle
has begun.
2. Locking the Door:
•
After programming the clean cycle and
pressing START pad, the control
energizes the lock relay. Voltage (120
VAC) is applied to the lock motor circuit.
Oven door must be closed before lock
motor can run. LOCK DOOR will flash
and control will beep until the door is
closed.
•
The lock motor begins to revolve and turns
a cam mounted to the motor shaft.
•
The words LOCKED DOOR will flash on
and off on the display while the lock motor
is in motion.
•
As the cam revolves about
1
/
2
revolution
(approximately 12 seconds), it has moved
the lock hook into a corresponding slot in
the oven door which secures the door.
•
The movement of the cam has also
closed lock switch 1 which signals the
control that the door is locked. The control
then removes power from the lock motor
circuit by de-energizing the lock relay.
•
The lock motor stops and lock switch 1 is
held closed by the cam through the clean
cycle.
•
The words LOCKED DOOR stop flashing
and remains illuminated in the display.
•
The word ON illuminates in the display.
3. During the Clean Cycle:
•
The broil relay closes (audible click) and
the broil burner begins to heat. The broil
burner only will operate during the first 30
minutes of the clean cycle followed by the
bake burner only during the remaining
time.
•
As the clean cycle progresses and the
temperature of the oven control area rises,
the cooling fan is activated.
•
A normally closed thermal switch is
mounted on a bracket in front of the
cooling fan. This switch is in the lock
switch circuit and will open the lock switch
circuit in the event of an over-temperature
condition in the control area (caused by a
stalled fan, fan switch failure, or similar
condition).
•
An -F2- (over-temperature) failure code
will appear on the control if this switch
opens while the oven is above 600°F
(315°C). With the oven between 400°F to
600°F (204°C to 315°C), the clean cycle
will be cancelled by the opening of the
switch and the control will revert back to
the time-of-day mode.
•
Below 400°F (204°C) the lock motor will
revolve continuously and the words
LOCKED DOOR will flash on the control
until the circuit is reestablished.
•
The oven will cycle to maintain an average
clean temperature of 830°F (433°C).
