6. Lint Screen Mechanism Problem “SCREEN FAULT”
A “SCREEN FAULT” message is generated by the incorrect state of the lint screen mechanism sensor
switch. The following information will address the correct signal, since it is associated with the Base Electrical
Junction Box.
a) PROBABLE CAUSES;
1a) The Lint Screen must be cleaned every five (5) drying cycles.
2a) Wiring back to the PLC (Programmable Logic Controller) 0, 8.
b) PROBABLE SOLUTIONS;
1b) The software has incorporated in it a clean lint screen verification, if the lint screen is not cleaned at
the end of five (5) drying cycles. The dryer will not allow another drying cycle until the lint screen
is cleaned.
2b) A defective lint drawer proximity switch.
• Have someone verify that PLC (Programmable Logic Controller) input L.E.D. (light emitting
diode) #8 lights, when the lint drawer is in and off when the drawer is out.
• Does L.E.D. (light emitting diode) #8 come “ON” when the lint drawer is out?
• If yes, wiring is OK
• If no, check associated:
• Proximity Switches and Wiring
• Check wiring back to the Base Junction Box.
• Check PLC (Programmable Logic Controller).
• Refer to Wiring Diagrams:
• Main Electrical Panel Diagram
• Base Electrical Junction Box Wiring Diagram.
• Retest; verify that the signal is operational.
