3.
Make sure the power cord is securely fastened to the terminal
block.
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.
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 16, page 12.
➔
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.

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.
