COMPONENT TESTS
Supply Connections Test
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.
1.
Unplug dryer or disconnect power.
2.
Remove the cover plate from the back of
the dryer.
3.
With an ohmmeter, check for continuity
between the neutral (N) terminal of the
plug and the center contact on the
terminal block. See illustration below.
➔
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 illustration
above.

Plug-to-terminal connections for electric

➔
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 electronic control without
disconnecting any wiring to it.
6.
With an ohmmeter, check for continuity
between the L1 terminal of the plug
(found in step 4) and BK (black wire)
terminal on the timer.
➔
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 or
repair the main wire harness and test
the dryer.
7.
Check for continuity between the neutral
(N) terminal of the plug and P2-1 (white
wire) on the electronic control.
➔
If there is continuity, go to the Timer
Test.
➔
If there is no continuity and the
mechanical connections of the wire
are secure, replace or repair the main
wire harness.
Timer Test
Perform the diagnostic test on page 1 to
determine that the timer motor advances
(should run continuously). If the timer does
not advance or fails the diagnostic test:
1.
Unplug dryer or disconnect power.
2.
Remove the wires from timer terminals.
3.
Check the timer motor resistance and
timer switching. The resistance (BU to
PT-1) should be 3 k
Ω
(
±
2). Use the timer
encoding table below for switching
conductivity, and refer to timer illustration
on page 2.
Reference contact continuity to timer - BK.

Motor Test
1.
Unplug dryer or disconnect power.
2.
Open the dryer door.
3.
Measure resistance between the motor
relay common (COM) terminal and the
P2-6 terminal on the electronic control.
1 to 6
Ω
should be measured.
➔
If resistance measurements are
outside 1 to 6
Ω
, perform the Thermal
Fuse Test and Door Switch Test,
page 5; and check harness continuity.
If they test good, replace the motor.
