Before servicing, check the following:
■
Makesure there is poweratthe wall outlet.
■
Has a household fuse blown or circuit breaker
■
tripped? Wasa regularfuse used? Use a timedelay fuse.
■
Is dryer vent properly installedand clear of lint
■
or other obstructions?
■
All tests/checks should be madewith
a VOM(volt-ohm-milliammeter) or DVM
(digital-voltmeter) having a sensitivity
of 20,000 Ω per volt DC or greater.
■
Check all connections before replacing
components.Look forbrokenorloose wires,
failed terminals,orwires notpressed into

TEST #3a Exhaust Thermistor
The machine control electronics monitors
the exhaust temperature using the exhaust
thermistor,and cycles the heaterrelay on
and off to maintain the desired temperature.
Begin with an empty dryer and a clean
lint screen.
1. Plug in dryer or reconnect power.
2. Start the Timed Dry cycle.
3. If after60 seconds, f3 e1 or f3 e2 flashes
in the display (on models withsevensegment
display) or the WET indicator flashes F3E1 or
F3E2(on models without seven segment display)
and the dryer shuts off, the thermistor or wire
harness is eitheropen or shorted.
Unplugdryeror disconnect power.
Check wire connections at the machine control
electronics andthermistor.SeeAccessing &
Removing theElectronicAssemblies,page 23,and
forthermistor location,see figure 10,page 18.
If wire connections aregood,remove the two
wires fromthethermistorand replacethe thermistor.
Reassembleall parts and panels.
Plug in dryer or reconnect power.
4. If f3 e1 or f3 e2 does not flashin the display
(on modelswith seven segment display) or the
WET indicator does not flash F3E1 or F3E2 (on
models without seven segment display),the
connections to the thermistor are good.Therefore,
check the exhaust temperature value at any or
all of the temperature levels in question, using
theTimed Dry cycle,and the following process:
Holda 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
temperaturesare as follows:
EXHAUST TEMPERATURES

(Kenmore) 105°±5° (41°±3°) temperature
* The measured overshoot using the glassbulb
thermometer in the exhaust outlet can be 30°F
(17°C) higher.
5. If the exhaust temperatureis not within
specified limits,unplug dryer or disconnect
power. Remove the P14 connector, then measure
the resistancebetween P14-3 (red-white wire)
and P14-6 (red-white wire) at the connector. See
figure 13,page 24 for connector location; and
