5b) Input 19 L.E.D. (light emitting diode) is not illuminating correctly on the PLC (Programmable Logic Controller) indicates that the signal to the PLC input is missing or the PLC is defective.

Check FUSE 2 on the main electrical panel

Check wiring back to the tumbler junction box

Check wiring back to the rear controls

Check PLC (Programmable Logic Controller) Refer to wiring diagrams:

Main Electrical Panel Diagram

Tumbler Junction Box Wiring Diagram

Rear Panel Controls Wiring Diagram

Retest; verify that the signal is operational

5.”DOOR OPEN” Problem

A “DOOR OPEN” message is generated by either the heater, load , or unload doors. The following in- formation will address the load and unload doors signals, since they are associated with the tumbler junction box.

a)PROBABLE CAUSES;

1a) Wiring back to the PLC (Programmable Logic Controller).

DS1-B = LOAD DOOR SWITCH DS2-B = UNLOAD DOOR SWITCH

b)POSSIBLE SOLUTIONS;

1b) For quick check of LOAD and UNLOAD signals on the PLC (Programmable Logic Controller) perform the following:

Remove factory air from the dryer

With the Control Voltage “ON,” open the LOAD doors and locate the LOAD door switch actuator.

Cycle the switch by hand and have someone watch PLC input indicator #6. It should go “ON” when the switch is down.

Open the UNLOAD doors and locate the UNLOAD doors switch actuator.

Cycle the switch by hand and have someone watch PLC input indicator #7. It should go “ON” when the switch is down. Do the associated L.E.D.’s (light emitting diodes) come “ON” when the switch is down?
