Convection Fan Motor
(
Continued)
Low speed reverse operation
As describe on page 51, the convection fan motor is a reversible fan motor. During normal operation, the motor
will run in one direction for a period of time based on the cook cycle. Then, the K5 relay will disengage for 10
seconds, allowing the fan motor to slow down and stop. The K6 relay will activate and reverse the direction, and
then the K5 Power relay will engage, staring the motor turning in the opposite direction. This procedure
continues throughout the cook cycle.
FIG A
shows the Convection Power relay (K5)
and the Convection directional relay (K6)
activated. In the wiring configuration shown
here, the fan will run at LOW speed and in a
clockwise rotation.
FIG B
shows the current flow for LOW speed
reverse. L1 Power flows through the N.O. contact
in the K5 relay (energized) to the common
terminal on the K6. The N.O. contact on K6 is
wired directly to the convection motor (Gray wire).
In reverse operation, the K6 relay is energized.
The N.O. contact of the K6 is internally connected
to the Common terminal of the K7.
L1 power flows through K6 to the K7 relay. The K7
is not energized in LOW speed so the power flows
Into the LOW speed capacitor (Green wire). It then
exits the LOW speed capacitor and then into the
HIGH speed Capacitor (orange wire).The power
then enters the HIGH speed capacitor. We now
have two capacitors in a SERIES circuit. Both
capacitors have a rating of 1.5 ufd giving a
total of 3.0 ufd for LOW speed reverse operation.

CAUTION
The convection circuit utilizes capacitors
in its operation which can store a charge
for long periods of time. Be sure to
discharge the capacitors before servicing
the convection components.
