6. Access the machine control electronics

without disconnecting any wiring to the

control board. See Accessing &

Removing the Electronic Assemblies,

page 11.

7. With an ohmmeter, check for continuity

between the L1 terminal of the plug

(found in step 5) and P9-2 (black wire) on

the machine control board. See figure 15,

page 11.

➔

If there is continuity, go to step 8.

➔

If there is no continuity, check that

wires to the terminal block are

mechanically secure. If so, replace the

main wire harness and test the dryer.

8. Check for continuity between the neutral

(N) terminal of the plug and P8-3 (white

wire) on the machine control board.

➔

If there is continuity, go to step 9.

➔

If there is no continuity and the

mechanical connections of the wire are

secure, replace the main wire harness.

9. Visually check that the P5 connector is

inserted all the way into the machine

control electronics.

10. Visually check that the user interface

assembly is properly inserted into the

front console.

11. If both visual checks pass, replace the

user interface assembly.

12. Plug in dryer or reconnect power.

13. Perform the Console Buttons and

Indicators Diagnostic test, page 1, to

verify repair.

14. If indicators still do not light, the

machine control electronics has failed:

➔ Unplug dryer or disconnect power.

➔

Replace the machine control

electronics.

➔

Plug in dryer or reconnect power.

➔

Perform the Console Buttons and

Indicators Diagnostic test, page 1 to

verify repair.

TEST #2 Machine Control

Power Check

This test is used to determine if power is

present at the machine control electronics.

NOTE: The drum light is controlled by the

machine control on all models.

1. Plug in dryer or reconnect power.

2. Open the door.

➔

If the drum light illuminates, then

power is present at the machine

control. Go to TEST #6, page 10.

➔

If the drum light fails to illuminate,

do not assume the machine control

electronics needs replacement.

Several conditions may cause the

drum light not to illuminate, including

a bad bulb. If the drum light does not

illuminate, go to TEST #1.

TROUBLESHOOTING TESTS

NOTE: These checks are done with the dryer

unplugged or disconnected from power.

TEST #1 Supply Connections

This test should only be done after

confirming proper voltage at the outlet.

1. Unplug dryer or disconnect power.

2. Remove the cover plate from the back of

the dryer. See figure 3.

3. Make sure the power cord is securely

fastened to the terminal block.

Figure 3. Remove the cover plate.

4. With an ohmmeter, check for continuity

between the neutral (N) terminal of the

plug and the center contact on the

terminal block. See figure 4.

➔

If there is no continuity, replace the

power cord and test the dryer.

➔

If there is continuity, go to step 5.

5. In a similar way, check which terminal of

the plug is connected to the left-most

contact on the terminal block and make a

note of it. This will be L1 (black wire) in

the wiring diagram. See figure 4 and the

appropriate wiring diagram, page 4.

➔

When this is found, go to step 6.

➔

If neither of the plug terminals have

continuity with the left-most contact of

the terminal block, replace the power

cord and test the dryer.
