C. Load Control A.D.P.S.T.
This Cycling Switch varies, according to its setting,
the percent on-time of the output as shown below:
the buzzer. The buzzer will continue to sound until the
knob is manually turned to "Hold" position where all
contacts are opened, (timer motor and buzzer turned
off).

INFINITE LOAD CONTROL SWITCH
The Load Control, as shown schematically, is con-
nected in series with the thermostat, thus providing a
variable rate of temperature rise to reach the ther-
mostat setting, as well as maintaining the temperature
at the final set temperature. Therefore, with the load
control set at Lo, it will take much longer to reach a
desired temperature than with a setting of Hi. The
cooking chart shows the necessary dial setting for
different food products.
To replace this switch remove the knob and the lock
nut. To reinstall, make sure the dimples on the face of
the switch fall in the slot of the switch panel in order to
prevent it from rotating.
D. Timer
(one or five-hour models).
The normally open and common contacts of the
electric timer are connected together, energizing the
timer motor when the knob is set to the desired posi-
tion. Once the timer completes its set interval (at the
zero mark) the common terminal disconnects from
timer motor (shuts the motor off) and connects with
To replace, remove the knob and the lock-nut—
reinstall same as item C.
2. BLOWER MOTOR
The blower motor has internal thermal protection, and
its sealed bearings do not require any lubrication. The
mounting of the blower assembly allows servicing from
inside the oven as follows:
Remove the fan cover.
Loosen the set screw on the centrifugal fan with
allen wrench.
Pull the centrifugal fan forward off of the motor
shaft with a wheel puller.
Remove the four nuts holding the motor mounting
plate. Pull the motor assembly forward and rest it on
the cavity bottom.
Remove the junction box cover and supply leads.
Rest the motor on its back. Remove four flat head
screws, lockwashers, nuts and spacers used to
fasten the motor mounting plate to the motor.
CAUTION:
The motor is suitable for connection to two
different voltage supplies. Check the connection
instruction inside the motor junction box cover to
assure the proper connection for the available voltage
supply.
The direction of rotation is clockwise as viewed from
inside the oven. The 1-phase motors are internally
designed for C.W. rotation. On 3-phase motors, inter-
change any two supply leads to convert C.C.W. to
C.W. rotation.
