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
