3. If after 60 seconds, F-22 or F-23 flashes
in the display and the dryer shuts off, the
thermistor or wire harness is either open
or shorted.
• Unplug dryer or disconnect power.
• Check wire connections at the machine
control electronics and thermistor. See
Accessing & Removing the Electronic
Assemblies, and for thermistor loca-
tion see Figure 10.
• If wire connections are OK, check ex-
haust thermistor resistance per step 5.
4. If F-22 or F-23 does not flash in the dis-
play, the connections to the thermistor
are good. Therefore, check the exhaust
temperature value at any or all of the
temperature levels in question, using the
Timed Dry cycle, and the following pro-
cess:
Hold a glass bulb thermometer capable of
reading from 90° to 180°F (32° to 82°C)
in the center of the exhaust outlet. The
correct exhaust temperatures are as fol-
lows:

bulb thermometer in the exhaust outlet can
be 30°F (17°C) higher.

5. If the exhaust temperature is not within
specified limits, or you have come here
from step 3, remove the P14 connector,
then measure the resistance between
P14-3 (red-white wire) and P14-6 (red-
white wire) at the connector. See Figure
16, for connector location; and Accessing
& Removing the Electronic Assemblies.
• If the resistance is OK, check P14-3
and P14-6 to machine ground.
• If resistance is greater than 0 (zero),
replace wiring harness.
NOTE: All thermistor resistance mea-
surements must be made while dryer is
disconnected from power.
The following table gives temperatures
and ranges for the associated thermistor
resistance values.

• If the thermistor resistance does not
agree with table, replace the exhaust
thermistor.
• If the thermistor resistance checks
agree with the measurements in the
table, replace the machine control
electronics.
TEST #4b Thermal Fuse
The thermal fuse is wired in series with the
dryer drive motor.
1. Unplug dryer or disconnect power.
2. Access the thermal fuse by first removing
the back panel. See Removing the Back
Panel, and for thermal fuse location see
Figure 10.
3. Using an ohmmeter, check the continuity
across the thermal fuse.
• If the ohmmeter indicates an open cir-
cuit, replace the failed thermal fuse.
