6-4
Timer Test
Perform the diagnostic test on pages 6-1 &
6-2 to determine that the timer motor advanc-
es (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 kΩ (±2). Use the timer
encoding table below for switching con-
ductivity, and refer to timer illustration on
page 7-2 or 7-5.
Reference contact continuity to timer - BK.
Timer Encoding Table
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, page 6-6, and Door Switch Test,
page 6-5; and check harness continuity.
If they test good, replace the motor.
4. Measure resistance between the mo-
tor relay common (COM) terminal and
ground. A high resistance (open) should
be measured.
If it does not, perform the Thermal Fuse
Test and Door Switch Test and check
harness continuity. If they test good,
replace the motor.

Supply Connections Test—Gas
1. Unplug dryer or disconnect power.
2. Remove the cover plate from the back of
the dryer and check that the power cord
is firmly connected to the dryer’s wire
harness.
3. Access the electronic control without
disconnecting any wiring to the control
board.
4. With an ohmmeter, check for continuity
between the neutral (N) terminal of the
plug and P1-2 (white wire) on the elec-
tronic control board. The left side of the il-
lustration below shows the position of the
neutral terminal (N) on the power cord
plug.
If there is continuity, go to step 5.
If there is no continuity, disconnect the
white wire of the harness from the pow-
er cord. Test the continuity of the power
cord neutral wire. If an open circuit is
found, replace the power cord. Other-
wise, replace the main wire harness.
5. With an ohmmeter, check the continuity
between the L1 terminal of the plug and
BK (black wire) on the timer.
If there is continuity, go to the Timer
Test.
If there is no continuity, disconnect the
black wire of the harness from the pow-
er cord. Test the continuity of the power
cord L1 wire as illustrated in step 4. If an
open circuit is found, replace the power
cord. Otherwise, replace the main har-
ness.
