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. (light emitting diode) #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
