WARNING
Electrical Shock Hazard
D
isconnect power before
servicing.
R
eplace all parts and
panels before operating.
Failure to do so can
result in death or
e
lectrical shock.
IMPORTANT
Electrostatic Discharge Sensitive
Electronics (ESD)
ESD problems are present everywhere. ESD
may damage or weaken the machine control
electronics. The new control assembly may
appear to work well after repair is finished,
but failure may occur at a later date due to
ESD stress.
Use an anti-static wrist strap. Connect
wrist strap to green ground connection
point or unpainted metal in the appliance
-OR- Touch your finger repeatedly to a
green ground connection point or
unpainted metal in the appliance.
Before removing the part from its package,
touch the anti-static bag to a green ground
connection point or unpainted metal in the
appliance.
Avoid touching electronic parts or terminal
contacts; handle machine control
electronics by edges only.
When repackaging failed machine control
electronics in anti-static bag, observe
above instructions.
DIAGNOSTIC GUIDE
Before servicing, check the following:
Make sure there is power at the wall outlet.
Has a household fuse blown or circuit breaker
tripped? Was a regular fuse used? Use a
time-delay fuse.
Is dryer vent properly installed and clear of lint
or obstructions?
All tests/checks should be made with a VOM
(volt-ohm-milliammeter) or DVM (digitalvoltmeter) having a sensitivity of 20,000 Ω
per volt DC or greater.
Check all connections before replacing
components. Look for broken or loose wires,
failed terminals, or wires not pressed into
connectors far enough.
A potential cause of a control not functioning
is corrosion on connections. Observe
connections and check for continuity with
an ohmmeter.
Connectors: Look at top of connector. Check
for broken or loose wires. Check for wires not
pressed into connector far enough to engage
metal barbs.
Resistance checks must be made with dryer
unplugged or power disconnected.
DIAGNOSTIC TESTS
These tests allow service personnel to test and
verify all inputs to the machine control electronics.
Y
ou may want to do a quick and overall checkup
o
f the dryer with these tests before going to

TROUBLESHOOTING TESTS
NOTE: These checks are done with the dryer
u
nplugged or disconnected from power.
TEST #1 S
upply Connections
This test assumes that proper voltage is present at
the outlet, and visual inspection indicates that the
p
ower cord is securely fastened to the terminal
block (electric dryer) or wire harness connection
(gas dryer).
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 Accessing & Removing the Electronic
Assemblies, page 9.
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, page 10.
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.
I
f there is continuity, go to step 8.
If there is no continuity and the mechanical
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 steps under DIAGNOSTIC: Console
Buttons and Indicators, page 1, to verify
repair.
13. If indicators still do not light, perform
TEST #2, page 5.
GAS 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. Check that the power cord is firmly connected
to the dryer’s wire harness. See figure 5.
4. Access the machine control electronics without
disconnecting any wiring to the control board.
See figure 16, page 9.
5. With an ohmmeter, check for continuity
between the neutral (N) terminal of the plug
and P8-3 (white wire) on the machine control
board. The left-hand side of figure 6 shows the
position of the neutral terminal (N) on the
power cord plug. Also see figure 17, page 10.
