a. PROBABLE CAUSES
1)The lint screen must be cleaned every five (5) drying cycles
2)Wiring back to the PLC (Programmable Logic Controller), 0, 8
3)Clogged lint screen or lint bag
4)Air pressure setting
5)Air pressure switch - PS3 or wiring back to the PLC (Programmable Logic Controller) b. PROBABLE SOLUTIONS;
1)Perform preventive maintenance and screen cleaning procedures.
2)Set correct pressure settings.
3)For a quick check of the AIR PRESSURE SWITCH WIRING, perform the following:
•Run a drying cycle
•Does the pressure switch’s indicator come “ON”?
•If “YES,” switch and its adjustment are okay
•If “NO,” check switch and its adjustment
•Verify that PLC (Programmable Logic Controller) input L.E.D. #5 comes “ON”
•Does L.E.D. #5 come “ON” when the switch is active?
•If “YES,” wiring is okay
•If “NO,” check:
•Switch, its setting and wiring
•Check wiring back to the base electrical junction box
•Check PLC (Programmable Logic Controller)
•Refer to the blueprints: Main Electrical Panel Diagram, Base Junction Box Wiring Diagram
•Retest; verify that the signal is operational
