TEST #3c Gas Valve
1. Unplug dryer or disconnect power.
2. Access the gas valve by first removing
the toe panel. See Removing the Toe
Panel, page 6-30.
3. Use an ohmmeter to determine if a gas
valve coil has failed. Remove harness
plugs. Measure resistance across ter-
minals. Readings should match those
shown in the chart. If not, replace coil.
Terminals Resistance
1 to 2 1365 ± 25
1 to 3 560 ± 25
4 to 5 1220 ± 50
IMPORTANT: Be sure all harness
wires are looped back through the
strain relief after checking or
replacing coils.
TEST #4 Moisture Sensor
NOTE: This test is started with the machine
completely assembled.
This test is performed when an automatic cy-
cle stops too soon, or runs much longer than
expected.
NOTE: Dryer will shut down automatically af-
ter 2-1/2 hours.
The following items are part of this system:
• Metal sensor strips
• Machine control electronics
1. Enter the Diagnostic Test #1 mode. See
procedure on page 6-18.

2. If a continual beep tone is heard as soon
as the diagnostic mode is started, a short
circuit exists in the moisture sensor sys-
tem.
• If this doesn't happen, go to step 3.
• Otherwise, go to step 4.
NOTE: Over drying may be caused by a
short circuit in the sensor system.
3. Locate the two metal sensor strips on the
inside right wall of the door well. Bridge
these strips with a wet cloth or finger.
• If a continual beep tone is heard, the
sensor passes the test. Go to step 4.
• If a continual beep tone is not heard,
go to step 6.
4. Unplug dryer or disconnect power.
5. Access the machine control electronics.
Remove the connector P3 from the circuit
board. Measure the resistance across
terminals 9 and 10.
• If the ohmmeter does not indicate (in-
finity) open circuit, go to step 7.
• Otherwise, measure the resistance
across pins 9 and 10 of connector P3
on the machine control board. If a re-
sistance less than 1 MΩ is measured
(with analog or digital ohmmeter), in-
spect the control board for any debris
bridging these pins. If no debris, re-
place the machine control electronics.
