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).
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.
If 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.
If there is continuity, go to step 6.
Problem
Possible Cause / Test
NOTE:
Possible Cause/Tests MUST be performed
in the sequence shown for each problem.
Won’t power up.
(No response when buttons are pressed.)
1. Supply connections. See TEST #1, at right.
2. Check harness connections.
3. Console electronics and housing assembly.
See TEST #6, page 8.
Won’t start cycle when Start button is pressed.
1. If number display flashes, check to be sure the
door is completely shut, and press and hold
down Start for about 1 second.
2. See TEST #3, page 5.
3. See TEST #7, page 9.
Won’t shut off when expected.
1. Check Pause/Cancel button.
2. Console electronics and housing assembly.
See TEST #6, page 8.
3. Moisture sensor. See TEST #5, page 8.
Control won’t accept selections.
Console electronics and housing assembly. See
TEST #6, page 8.
Won’t heat.
1. Heater. See TEST #4, page 6.
2. Check harness connections.
3. See DIAGNOSTIC: Displaying Line Voltage,
page 2.
4. Check installation.
Heats in air cycle.
Heater. See TEST #4, page 6.
Shuts off before clothes are dry.
1. Check the dryness setting for auto cycles.
2. Check for full lint screen.
3. See DIAGNOSTIC: Displaying Inlet Air Flow,
page 2.
4. Check for clogged vent.
5. Moisture sensor. See TEST #5, page 8.
6. Dryness level adjust. See TEST #5a, page 8.
Pushing Power button causes dryer to beep,
but no indicators light.
1. Check console electronics harness connections
to the machine control.
2. Replace machine control electronics. See
Accessing & Removing the Electronic
Assemblies, page 9.
