b. Programmable Logic Controller (PLC) Replacement

1) Discontinue electrical power to the dryer.

2) Mark and identify the wires that will be removed for proper reinstallation.

3) To remove the PLC from the mounting rail, using a screwdriver, very carefully pull out the mounting clip on the bottom of the PLC and lift the unit out of the rail.

4) To replace the PLC, push in the top of the PLC into the rail and then snap in the bottom of the unit.

5) Replace the wires removed in Step #2.

6) Reestablish electrical power to the dryer.

c. Phase 7 Microprocessor Controller (Computer) Display Board Replacement

1) Discontinue electrical power to the dryer.

2)Carefully unplug JPD3 connector, the JPD4 connector, and the keyboard (touch pad) ribbon cable.

3)Disconnect the common connector power cable (JPD6).

4)Loosen and remove the two (2) screws securing the Phase 7 microprocessor controller (computer) display board and then remove the computer from the door.

5)To install new Phase 7 microprocessor controller (computer) display board, reverse Step #4 thru Step #1.

d. Phase 7 Microprocessor Controller (Computer) Input/Output (I/O) Board Replacement

1)Discontinue electrical power to the dryer.

2)Carefully unplug the connectors from JPM9, JPM7, JPM11, JPM8, JPM10, JPM1, JPM2, JPM3, and JPM4. Stamped on the microprocessor controller (computer) input/output (I/O) board.

3)Remove the five (5) Phillips head screws securing the I/O board to the control panel.

4)Carefully remove the I/O board from the two (2) stand offs.

NOTE: FOR REPLACEMENT OF THE NEW I/O BOARD, IT IS IMPORTANT TO HANDLE WITH CARE TO AVOID ANYELECTRICAL SHOCKS. DAMAGE MAY OCCUR. PROPER STATIC PRECAUTIONS SHOULD BE TAKEN.
