dryer gives d68 code

Matthew,E68 Key (button) StruckFault
One of the keys (buttons) is stuck closed (active).
Enter function test mode and perform key (button) test to determine which
button is at fault. Carefully free the and perform the test again. If button is free but the key struck code still exists, replace electronic control.

READING ERROR CODES
1. Rotate cycle selector knob to the 3 O’clock position.
2. Press and hold the Select and Pause Cancel buttons simultaneously for six seconds.
3. Immediately after, press and hold the START and Pause Cancel buttons simultaneously for 4 seconds.
4. Rotate the cycle selector knob to the 2 O’clock position. The four indicator lights of Drying, Cool Down, Wrinkle Rid
(Press Saver), and Clean Lint Filter will flash the number of times for the first digit of the code and the START indicator
light will flash the number of times for the second digit. Take separate counts of each indicator light, then repeat to
confirm in order to be accurate in identifying the proper error code. The code is obtained by counting the number of times
the lights flash. Example E24: The four indicator lights would flash twice indicating the 2 and the START indicator light
will flash four times indicating the 4. The four indicator lights and the START indicator light start flashing at the same
time. The control will pause for 2 seconds, then repeat the code.
NOTE: A letter appearing in the code stands for a number higher than nine. A = 10 B = 11 C = 12 D = 13 E = 14 F = 15
Example Code E4A: the first digit would be 4 and the second digit would be 10. The four indicator lights would blink four
times and the START indicator light would blink ten times. Troubleshoot the problem by using the chart below.
To move on to the next code, press the OPTIONS button.
To clear code, press the Select button. Code will be cleared when mode is exited.
To exit this mode, simultaneously press and hold the Select and Pause Cancel buttons for six seconds.
Error Code Label Description Solution
E10 General EEPROM
Fault
Problem with communication
between EEPROM and the
microprocessor.
Clear code, exit mode and start dryer. If problem persists, replace electronic
control.
E11 Checksum Error Problem with communications or
memory did not check, one has
become corrupted.
Clear code, exit mode and start dryer. If problem persists, replace electronic
control.
E12 Non fatal R/W
error
Problem reading or writing to the
memory or input/output.
Clear code, exit mode and start dryer. If problem persists, replace electronic
control.
E24 Control NTC Short
Circuit
Control thermistor or its wiring is
shorted.
Remove wires from control thermistor. Measure resistance of thermistor. If
reading is not 50 K (± 10%), replace thermistor. If reading is within 50 K (±
10%), check wiring between thermistor and electronic control. If good,
replace electronic control.
E25 Control NTC Open
Circuit
Control thermistor or its wiring is
open.
Remove wires from control thermistor. Measure resistance of thermistor. If
reading is not 50 K (± 10%), replace thermistor. If reading is within 50 K (±
10%), check wiring between thermistor and electronic control. If good,
replace electronic control.
E4A Program Timeout
Fault
The drying time has exceeded
program time for that cycle.
Press Pause Cancel and SELECT buttons for 6 seconds to exit test modes.
Position cycle selector to NORMAL, temperature selector to HIGH HEAT
and touch START. Check for anything that would extend dry times such as:
no heat, restricted vent, blower fan blade broken or loose, dryer installed in
closet with solid door, or bad connection in moisture sensor bar circuit or
dirty bars. If dryer operates normally but code returns, replace electronic
control.
E5B Heater Fault (no
heating)
Temperature reading of control
thermistor has not changed in a
certain amount of time.
Position cycle selector to NORMAL, temperature selector to HIGH HEAT
and touch START. Measure voltage across terminals on relay RL2 (heater
E68 Key (button) Struck
Fault
One of the keys (buttons) is stuck
closed (active).
Enter function test mode and perform key (button) test to determine which
button is at fault. Carefully free the and perform the test again. If button is
free but the key struck code still exists, replace electronic control.
E8C Too many trips in a
period of time.
The safety (high limit) thermostat
has tripped too many times within
a certain period of program time.
Check for blocked lint filter, blocked exhaust, air leaks around air duct,
broken blower fan blades, worn or loose drum seals, dryer installed in closet
with solid doors or door seal not correctly seated.
EAF Watch Dog Reset Microcontroller has been reset by
internal Watchdog timer.
Clear code, exit mode and start dryer. If problem persists, replace electronic
control. Pub# 31-16529 P/N134859700
FUNCTION TEST SEQUENCE
1. Position the cycle selector knob to the 12 O’clock position.
2. Press and hold the Select and Pause Cancel buttons simultaneously for six seconds.
3. Immediately after, press and hold the START and Pause Cancel buttons simultaneously for 4 seconds.
The control will enter test mode, the buzzer will sound 3 times and all LED’S will rapidly flash.
After entering the test mode, the program knob can now be rotated to select the following tests:
Rotate the program knob clockwise from the start position:
1 turn: Drive motor runs; heat source is on. Drying LED is lit. Control thermistor reading is displayed.**
2 turns: Drive motor runs; heat source is off. Cool Down LED is lit.
3 turns: Drive motor runs; heat source is off. Drying and Cool Down LED’s are lit and the MORE DRY LED should be
ON. Opening the door (press in on door switch plunger) and placing a finger on the both moisture sense bars
at the same time will make the DAMP LED come on.
4 turns: Drive motor runs; heat source is off.
Key test:
a. When the TEMP button is pressed, all the TEMP LED’s should light. If the Temp selector rotary
knob is rotated, there should be a key beep with each setting.
b. When the DRYNESS button is pressed, all the dryness level LED’s should light.
c. When the OPTION or Select button is pressed, all the Option LED’s should light.
d. When the START button is pressed, all the cycle status LED’s should light.
e. When the Pause Cancel button is pressed, all the Cycle status LED’s should light.
5 turns: Drive motor runs; heat source is off. Cool Down LED is lit.
6 turns: Drive motor runs; heat source is on. Drying LED is lit.

The dryness LED’S are used to determine the control thermistor temperature reading. The number of flash
