Thermoactuator And Shake Out Circuit - Dexter Laundry T300 Parts & Service Manual

Notes
Unlock Thermoactuator and Shake Out Circuit
70 seconds before the end of the cycle the main control PCB signals the relay PCB to remove 120VAC
from the orange/blue wire at the P-17 connector on the lock thermoactuator. This allows the lock thermo-
actuator time to cool and retract by the end of the cycle. To insure that the lock thermoactuator has re-
tracted by the end of the cycle, 1 minute prior the end of the cycle, the unlock thermoactuator is powered
with 120VAC through the orange/red wire from the P-17 connector of relay PCB. The unlock thermoactua-
tor moves the complete bracket assembly away from the white door lock actuator allowing it to drop at
the end of the cycle, unlocking the door. The basket will come to a stop from spin speed with the assis-
tance of dynamic braking resistors wired to the variable frequency drive. (See wiring diagrams for quanti-
ties and resistor ohm values). The washer will then tumble for 45 seconds to let the clothes shake loose
from the basket and then stop.
End of Cycle and Door Open Circuit
Once the machine stopped, 3 things occur:
1. The enunciator will signal for 3 seconds letting the user know that it is the end of the cycle.
2. The Display of the Washer will scroll "CYCLE DONE THANK YOU".
3. The main control PCB signals the relay PCB to remove power from the white/red wire at P-17 which
allows the door lock solenoid to unlock. When the loading door is opened, the S1,S2,S3,S5 switches are
opened. The machine is now ready to accept coins again.
