Motor in spin cycle
Current flows from L1 through contact T1 to T2 of the timer to the lid lock. When the lid is closed, the lid lock
arm closes a set of contacts inside the lid lock applying power through the lid lock bimetal element. As current
flows through the bimetal element in the lid lock, it forces the locking arm to engage the lid strike. This provides
power to terminal T17 of the timer. Terminal T17 is closed to terminal T14 of the timer. T14 is closed to terminal T12
of the timer that supplies power to terminal M2 of the drive motor. M2 is connected in the motor to the run
centrifugal switch. When the motor is not running, the output terminal of the run centrifugal switch is connected to
one end of the high speed run winding and to terminal M6 of the motor. The other end of the high speed run winding
is connected internally in the motor through the thermal fuse to terminal M3 of the motor. Terminal M3 is connected
to neutral allowing current flow through the high speed run winding. Terminal M6 of the motor is connected to
terminals T7 and T4 of the timer. During spin, T7 is closed to terminal T5 of the timer, which is connected to
terminal M1 of the motor. Terminal M1 is connected to one end of the start winding. The other end of the start
winding is connected to motor terminal M5 through the start winding centrifugal switch. Terminal M5 of the motor
is connected to one end of the start capacitor. The other end of the start capacitor is connected to terminal T8 of
the timer. T8 is closed to terminal T9 of the timer which is connected to terminal M7 of the motor. Terminal M7 of
the motor is connected through the motor thermal fuse to terminal M3 of the motor that is connected to neutral.
Current now flows through the start winding, the start capacitor (that changes the phase of the current) to neutral
and the motor starts to turn.
Note:
The drive motor always starts at high speed then changes to the speed switch setting.
