GE Harmony Dryer dries fine one time won't quit sensing the next

It will run perfectly one time, dries on selected cycle, gets to the end, senses, cool down, perfect. The next time it runs forever, won't quit sensing and never dries. The vent is clear and it seems to be getting warm. We had the thermistor replaced a few months ago. The problem seems to come and go almost every other use.

Any help would be appriated!!!

The thermostatic fuse is getting hot during the run cycle and then staying open until the dryer cools down completely.

You may fix just by cleaning out the entire dryer. Remove the top cover and vacuum out thoroughly. Replace a torn lint screen and make sure your exhaust conduit is not leaking lint everywhere.

If you can't fix by cleaning, you will have to replace the thermostat which is a $5 part byt a $100 repair.

Dryer is only 4 years old, was drying perfect one load, then the next its not drying. Takes 3-4 times to get load completely dry.


ELECTRIC Dryer no heat or little heat, or shuts down to fast:

Check your venting and lint basket. Check blower for lint build up and blower wheel obstruction., test by trying to turn the wheel manually by hand (should be easy) May have to remove cabinet or front/back plate to get to it)

Next check the heating element itself with a meter for continuity OHMS CLOSED CIRCUIT. If not its defective.

Check dryer Terminal block prongs both outside prongs should give combined 220, and 110 each if u check 1 outside & 1 center (ground) prong. Also check house electrical outlet for full voltage. 220 because if u only get half or 110 volts you will be able to run the machine which uses only 110 to run motor but not the heater which uses a full 220,

Check the thermal cut off, the cycling and the hi limit thermostats.
For continuity or OHMS. If no ohms or resistance they need replacement.

Lastly check your moister sensor. ( located inside the dryer door usually) Especially if machine seems to shut down early and clothes are still wet.
Test with a meter at room temperature and it should show continuity.
A failed moisture sensor will affect the dryer run time in the automatic moisture sensing cycle but it will not affect the heating of the dryer or the timed cycle.

This machine was spinning with an uneven load and stopped working so I emptied the machine and took it apart. I found the shock absorber on the tub needed to be put back together so I fixed that problem...


The error E68 means the ccu has sensed a stuck button on the console. MANY times this is a false error and means that either the ccu or interface must be replaced, but SOMETIMES, there really is a stuck button. TRy to run a diagnostic using the instructions I have provided below, let me know if you need any help with it.
1. Press and hold Select and Cancel buttons simultaneously for 6 seconds to reset the control. The buzzer will sound
1 time and "rES" will be shown briefly in the display.
2. Immediately after, rotate cycle selector knob 5 turns counter-clockwise to the second position from the bottom.
Press and hold the Options and Cancel buttons simultaneously for 2 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 cycle selector knob can now be rotated to select the following tests:
Rotate the cycle selector knob clockwise from the starting position:
0 turns: All LED's will flash.
1 turn: Drive motor runs; heat source is on. Drying LED is lit. "H" and the control thermistor reading will toggle
back and forth in the display.
2 turns: Drive motor runs; heat source is off. Cool Down LED is lit and "AF" (Air Fluff) is displayed.
3 turns: Drive motor runs; heat source is off. Drying and Cool Down LED's are lit and numbers appear in the
display showing moisture sensor readings. 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 numbers decrease. In controls that
do not have a digit display, 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 Temperature key is pressed, all the temperature LED's should light.
b. When the Dryness key is pressed, all the dryness level LED's should light.
c. When the Options or Select key is pressed, all the Option LED's should light.
d. When the Start/Pause key is pressed, all the cycle status LED's should light.
e. When the Cancel key is pressed, all the cycle status LED's should light.
5 turns: Drive motor runs; heat source is off. Cool Down LED is lit. Control thermistor reading is displayed.
6 turns: Drive motor runs; heat source is on. Drying LED is lit. Control thermistor reading is displayed.
7-11 turns: All LED's will flash
To EXIT test mode, press and hold the Select and Cancel buttons simultaneously for 6 seconds or disconnect power
from dryer. Dryer will be reset for regular operation.
If you cant even enter this mode at all, your interface will have to be replaced. There is no way to determine whether its the intrface OR ccu, but in my experience, it's usualy the interface that ends up needing replacement. Here is the part to order.

Kenmore dryer 110.86864100 - Where is the moisture sensor?


Ain't no moisture sensor. This is is not an electronic sensing machine. It uses another method to determine dryness. An orange wire connects to the base of the heating element. The timer motor is driven by power from it in auto dry. The timer motor is VERY slow. Slower than most dryer timer motors.As the clothes get dryer the heat is not needed so the element is turned off by the control thermostat which is mounted next to the skinny white fuse on the blower housing. This allows for the turtle like motor on the timer to advance. Once the clothes get to the point of dryness the heater stays off way longer and the timer motor advances on over to the cool down and carry on over to the end of cycle. So the clothes won't always be dry due to factors like lint buildup in the blower housing, venting to outside and so forth. having said that my mom bought a brand new Kenmore dryer and I set it on 55 minutes timed drying. At the end of that them clothes is still damp. I then set it to auto dry high heat and that usually gets em dry. I think the main probo with this dryer is the thermostat ain't set as high as older models to keep the heat at a moderate temp so that the limits won't blow on models in apts and such. Just a theory.

Dryer gets hot and turns off


Hello there:
A lot of the times the problem lies with in the Cycling thermostat that is going out Although this isn't a common problem, one of the thermostats that controls the temperature in your dryer may break and cause the dryer to heat poorly.and can make the dryer stop working after it is working for a given amount of time If so, you need to replace it.
Next is the The thermostat is usually a small, round, black device mounted to an oblong steel plate. The plate is mounted to the internal ductwork with two screws.
It overheats and shuts down due to a bad thermostate Usually when an electric dryer overheats it's because of a defective cycling thermostat or a clogged vent system. Clean any lint from the internal and external ductwork, and/or replace the cycling thermostat (read about cycling thermostats in "Drying is too slow," above). It seems to run forever If your dryer seems to run forever, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system. Normally, this is what happens during an automatic cycle: The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees. When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.) The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again. This cycle continues until the clothes are dry. But...if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.

AD is auto dry you may need to clean the sensor or you may have a fauilty one ...Auto Dry Loads dried using the Towels, Heavy Duty, Normal, Perm Press, and Delicates cycles will dry automatically at the selected temperature to the desired dryness level. The dryer uses sensing bars to sense the moisture level of the load as it tumbles through heated air. Auto Dry cycles save time and energy and protect fabrics. The estimated drying time will be displayed for about 5 minutes, then the outside of the display will light up in a circular track to indicate the drying time is automatically being determined by the sensors. When the load has reached the selected dryness level, it will continue to tumble, unheated, during a Cool Down period. This helps reduce wrinkling and makes items easier to handle during unloading. The estimated Cool Down time will be displayed. Drying time varies depending on size and dampness of load and fabric type. If the load is too small or almost dry, the sensing bars may not detect enough moisture to continue the cycle and the cycle may end after a few minutes. Select a Timed Dry setting to dry such loads. Room temperature and humidity, type of installation and electrical voltage or gas pressure can also affect drying time. For cycle selection turn the knob on the front of the dryer control panel. The light will illuminate next to the cycle selected. The following is a brief description for what cycles should be chosen for certain items and materials to be dried.
