3a) The L.E.D.’s illuminating on the PLC (Programmable Logic Controller) indicate that the wiring to the PLC is correct.

Check that the respective outputs of the PLC are also illuminating when the FORWARD and REVERSE buttons are being pressed.

PLC OUT PIN 1 = DRUM REVERSE PLC OUT PIN 2 = DRUM FORWARD

If output indicators are functional, however the tumbler (basket) doesn’t respond: Check wiring on the MAIN ENCLOSURE PANEL (Refer to the ADS-464 MAIN PANEL WIRING DIAGRAM)

3b) L.E.D.s (light emitting diodes) are not illuminating correctly on the PLC (Programmable Logic Controller) indicate that the signal(s) to the PLC inputs are missing.

Check FUSE 2 on the main electrical panel

Check wiring back to the tumbler (basket) junction box

Check wiring back to the rear controls

Refer to the blueprints:

Main electrical panel diagram

Tumbler junction box wiring diagram

Rear panel controls wiring diagram

Retest

e. PROBABLE CAUSES;

1)Rear panel disconnect plug

2)Defective switch

3)Wiring back to main electrical enclosure f. POSSIBLE SOLUTIONS;

1)If the “O UNLOAD 1” switch doesn’t respond when selected:

Verify that the rear panel controls disconnect plug is indeed connected. This disconnect plug allows for the removal of the rear control panel for dryer servicing

2)Defective “O UNLOAD 1” Selector Switch
