Operational Control Sequence - Fisher & Paykel DE7027J1US Service Manual

Operational Control Sequence

1.1.1 Motor Operation
The motor runs on the 120V circuit of the dryer. Power is supplied into the RL2 relay.
Power is then fed through both the start and run windings on the motor. The centrifugal switch then disengages
the start winding once the motor has started.
In the motors neutral circuit there is an internal overload. The neutral circuit then runs through the door switch
and to the mains terminal block.
If reverse drum is selected, the motor terminals 3, 7, 8 and 9 are switched by the RL5 relay in order to change
the drum direction. The sequence is defined by 4 minutes in CCW, 40 seconds in CW direction and a pause of 5
seconds every direction change.
