-Refer to blueprints:

-Main electrical panel diagram

-Tumbler junction box wiring diagram

-Rear panel controls wiring diagram

-Re-test

0 UNLOAD 1 Selection

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

-Shut power off at the main breaker and remove the rear panel and check switches using an OHM meter; replace if defective.

3.Wiring back to the main electrical enclosure

-With the control voltage “ON” Front Panel “GREEN” Button

-Select “1” on the “O UNLOAD” switch located on the rear control panel. Does PLC (Programmable Logic Controller) IN PIN 19 = UNLOAD, REAR PANEL light?

-If “YES,” refer to section 3a

-If “NO”, refer to section 3b

3a) The L.E.D. (light emitting diode) “ON” on the PLC (Programmable Logic Controller) indicates are also illuminating when the O UNLOAD 1 selector switch is on “1.”

PLC OUT PIN 7 = UNLOAD DOOR (OPEN)

PLC OUT PIN 10 = FRONT UP

-If output indicators are functional, however the UNLOAD DOORS of FRONT UP commands are not executed correctly:
