C. Load control. A.D.P.S.T. cycling Switch varies,
according to its setting, the percent on-time of the
output as shown below:
INFINITE LOAD CONTROL SWITCH
The Load Control, as shown schematically, is
connected in series with the thermostat, thus
providing variable rate of temperature rise to reach
the thermostat setting, as well as maintaining at the
final set temperature. Therefore, with 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, 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 position. Once
the timer completes its set interval (at zero mark) the
common terminal disconnects from timer motor
(shuts the motor off) and connects with 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).

BLOWER MOTOR
The Blower Motor has internal thermal protection, and
its sealed bearings do not require any lubrication. The

Pull airotor forward off of the Motor Shaft with wheel
puller.
Remove the (4) nuts holding the motor mounting
plate.
Pull the motor assembly forward and rest on cavity
bottom.
Remove the junction box cover and supply leads.
Rest the motor on its back. Remove the (4) flat head
screws, flex lock nuts and spacers used to fasten
the Motor Mounting Plate to the Motor (Note:
Spacers are counter bored to receive head of flat
head bolt. Be sure counter bored end of the
spacers face front of the replacing motor).
Caution: The motor is suitable for connection to two
different voltage supplies. Check the connection in-
struction inside the Motor Junction Box Cover to assure
proper connection for the available voltage supply.
