7. Measure the resistance across each
of the outermost contacts and the
center terminal (ground connection).
If a resistance less than infinity is
measured, replace the sensor harness.
8. If moisture sensor diagnostic test passes, check
the thermistor: Perform TEST #4a, pages 16–17.
If the problem persists after replacing the
moisture sensor and thermistor, replace the
machine control electronics.
TEST #5a Adjusting
Customer-Focused Drying Modes
NOTE: If the customer is complaining about the
clothes being damp and the moisture sensor
passes TEST #5, step 3, the total dry time can be
lengthened by changing from a "CF1" (standard
auto cycle) to a "CF2" (15% more drying time) or
"CF3" (30% more drying time) auto cycle.
1. In Standby mode (dryer plugged in but not
powered up), press and hold the Dryness Level
(Sensor Cycles Dryness on Maytag models)
button for 5 seconds. The dryer will beep and
the current drying mode will be seen on the
display. The factory default value is "CF1".
2. To select a different drying mode, press the
Dryness Level or Sensor Cycles Dryness button
again. The dryer display will flash and show cf2,
cf3, or cf1.
3. With the display flashing the selected auto
cycle mode, press the Start (Start/Pause on
Maytag models) button to save the drying mode
and exit diagnostics (the Start [Start/Pause on
Maytag models] button in this mode does not
start a drying cycle). The result will be stored in
EEPROM of the control board, and will be retained
after a power loss.
4. Press the Pause/Cancel (Whirlpool models),
Start/Pause (Maytag models), or Stop (Amana
models) button at any time to cancel changes
and exit from this mode.
