Motor Care
The motor on your convection oven is maintenance free
since it is constructed with self-lubricating sealed ball
bearings. It is designed to provide durable service when
treated with ordinary care. We have a few suggestions
to follow on the care of your motor. When the motor is
operating, it cools itself internally by air entering at the rear
of the motor case, provided proper clearance has been
allowed.
Since the blower wheel is in the oven cavity it is at the same
temperature as the oven. If the motor is stopped while the
oven is hot, the heat from the blower wheel is conducted
down the shaft and into the armature of the motor. This
action could shorten the life of the motor.
We recommend, at the end of the bake or roasting period,
when the oven will be idle for any period of time, or before
shutting down completely, that the doors be left open
slightly. On the 45 series controllers press the COOL DOWN
key on the control panel. The fan will continue to run until
the oven cools down to 150°F (66°C).
At the end of the day, press the ON/OFF key, for the 45 series
controllers to activate the Auto Cool Down feature. The fan
will run on high until the oven cavity drops below 150°F
(66°C). When the oven temperature drops below 150°F (66°C)
the oven turns off . This feature protects the oven motor
from pre-mature failure. On the 20 series controllers, push
the rocker switch to COOL position. Once cool set the rocker
switch to OFF.
NOTE: Optional cool-down will be achieved with the door
open slightly.
