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:
60
