If E1 or E2 does not flash in the display, the
connections to the thermistor are good.
Therefore, check the thermistor’s resis-
tance value at any or all of the temperature
levels in question, using the Timed Dry
Cycle, and the following process:
Hold a glass bulb thermometer capable of
reading from 32
⋅
to 82

C (90

the center of the exhaust outlet. The fol-
lowing table shows the correct exhaust
temperatures.
TEST #3b: THERMAL FUSE TEST
1.
Unplug dryer or disconnect power.
2.
Access the thermal fuse by first removing
the toe panel.
• Gas Dryers Only: The thermal fuse is
wired in series with the dryer gas valve.
If the thermal fuse is open, replace it.
• Electric Dryers Only: The thermal fuse
is wired in series with the dryer drive
motor. If the thermal fuse is open, re-
place it.
TEST #3c: GAS VALVE TEST
(GAS DRYERS ONLY)
1.
Unplug dryer or disconnect power.
2.
Access the gas valve by first removing the
toe panel.
3.
Use an ohmmeter to determine if a gas
valve coil has failed. Remove harness
plugs. Measure resistance across termi-
nals. Readings should match those shown
in the chart below. If the readings are not
as listed, replace the gas valve coil.
IMPORTANT: Be sure all harness wires are
looped back through the strain relief after
checking or replacing coils.
5.
If the exhaust temperature is not within
specified limits, use the following table,
and check the resistance of the thermistor.
NOTE: All thermistor resistance measure-
ments must be made while dryer is un-
plugged or disconnected from power.
The table shown above gives the resis-
tance values that should be observed for
the various temperature settings. If needed,
use table at the top of the right column to
find the temperatures and their associated
resistance values.
• If the thermistor resistance checks
within normal limits, replace the elec-
tronic control board.
