Dryer does not heat:
1. Unplug dryer or disconnect power.
2. Remove the toe panel to access the ther-
mal components. See Removing the Toe
Panel, page 6-30. Locate the compo-
nents using Figure 6.

3. Perform TEST #3b. If the exhaust high
limit manual reset is OK, go to step 4.
4. Locate the high limit thermostat. See Fig-
ure 6. Measure the continuity through it
by connecting the meter probes on the
black wires.
• If there is an open circuit, replace the
high limit thermostat.
• Otherwise, go to step 5.
5. Perform TEST #3c. If this is OK, replace
the machine control electronics.
Heat will not shut off:
1. Unplug dryer or disconnect power.
2. Access the machine control electronics.
See Accessing & Removing the Electron-
ic Assemblies, page 6-28. Measure the
resistance between P3-15 (red wire) and
P3-16 (black wire).
3. Set the multi-meter to the diode check
setting.
4. Touch the red lead of the meter to the
black wire of the temperature sensor and
the black lead of the meter to the white
wire of the sensor. The meter should read
open (infinite).
5. Next, reverse the leads so the black me-
ter lead contacts the black wire and the
red meter lead contacts the white wire.
You should read approximately 1.8 on
the meter.
6. With the meter still connected, grasp the
probe tightly in your hand and the meter
reading should slowly decrease as your
hands warm the probe.
If any of these tests fail, replace the tempera-
ture sensor.
