TROUBLESHOOTING TESTS

NOTE: These checks are done with the dryer
unplugged or disconnected from power.
TEST #1 Supply Connections
This test assumes that proper voltage is present
at the outlet, and visual inspection indicates
that the power cord is securely fastened to the
terminal block (electric dryer) or wire harness
connection (gas dryer).
Figure 3. Remove the cover plate.
ELECTRIC DRYER
1. Unplug dryer or disconnect power.
2. Remove the cover plate from the top right
corner of the back of the dryer. See Figure 3.
3. 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 4.
4. 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.

• When this is found, go to step 5.
• 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.
5. Access the machine control electronics
without disconnecting any wiring to the
control board. See figure 16.
6. With an ohmmeter, check for continuity
between the L1 terminal of the plug (found
in step 4) and P9-2 (black wire) on the
machine control board. See Figure 17.
• If there is continuity, go to step 7.
• 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.
7. 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 8.
• If there is no continuity and the mechan-
ical connections of the wire are secure,
replace the main wire harness.
8. Visually check that the P5 connector is
inserted all the way into the machine
control electronics.
9. Visually check that the console electronics
and housing assembly is properly inserted
into the front console.
10. If both visual checks pass, replace
the console electronics and housing
assembly.
11. Plug in dryer or reconnect power.
12. Perform the Console Buttons and Indicators
Diagnostic test to verify repair.
13. 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 to verify repair.
