Works on all cycles except that on the Automatic dry Miser setting the dryer stops mid cycle. All other cycles work fine and run through the complete cycle.

the way this works is you set the timer to say more dry,you start it and the heat comes on,when the dryer reaches temp the heat shuts down and the timer starts to advance,it will move a little until the heat comes on and it stops advancing,dryer heats up and it does this until the clothes are dry,when on timed dry there's a clock motor on the timer and the timer uses the clock motor to count down.this is the difference,now does the timer advance at all,if not you could have a bad timer or the heater element is touching metal and grounding,you can start the dryer on air fluff and see if it gets hot, also try running it on timed dry and see if it advances to off or does it stop at a certain point and doesn't go to off,or if you have a volt meter,pull off the vent line,remove the back panel,remove the wires going to the heating element,set the meter to say 20k ohms,touch the leads together and you should see anything but 1,now touch one lead to one side of the element and the other lead to the metal case that covers the element,if you get any reading other than 1 the element is grounding to the metal case,check both sides like this,also while you have the back open,did you remove the metal duct that the lint filter slides down into,if not do it but you said you changed a gasket there so i'm sure you did this,if you look to the right of the duct you'll see the thermal fuse and the cycling thermostat remove them and check them out,if you had that much lint in there they probably are covered with lint also,the cycling thermostat tells the dryer when to cycle when it gets hot and cool.if the heater isn't grounded most likely you have a bad timer,you can run it on timed dry and see if it gets stuck on a certain spot and doesn't fully advance to offhope this helps you out

If you are saying the timer does not advance then it is probably a bad timer. However you may have another problem if it is just the automatic dry cycle that doesn't work. Most timers have a time cycle with minutes. If that works but the other auto cycles do not work, then one of the temperature sensors is not working. If the time cycle doesn't advance at all then the drive motor on the timer is bad. Complete timer needs replaced.

Hello,
What the automatic dry miser is, is a sensor that measure how dry the clothes are and will adjust the time its going to take to dry the clothes throughout the entire cycle. If at the beginning it estimate it will take 40 minutes to sry a load but they are dry in only 25 minutes the dryer knows the clothes are dry and cuts the dryer off. Saving 15 minutes of unneeded gas and electric that it would run and waste power and gas since the clothes were dry already.

Hey Bio, Its either the timer or the moisture sensor.

Either the control board or the humidity sensor is bad.

You can make adjustments to your Automatic Cycles by adjusting the Factory Dryness Level:
Changing the Automatic Cycle settings to increase or decrease drying time:
If all your loads on all Automatic Cycles are consistently less dry or more dry than you would like, you may change the default settings to increase or decrease the default dryness
level.

Your automatic drying settings can be adjusted to adapt to different installations, environmental conditions, or personal preference. This change is retained and will affect all of your
Automatic Cycles, not just the current cycle/load. There are 5 drying settings, which are displayed using the time display:
0 Much wetter clothes, 30% less drying time.
1 Slightly wetter clothes, 15% less drying time.
2 Factory preset dryness level.
3 Slightly drier clothes, 15% more drying time.
4 Much drier clothes, 30% more drying time.
TO CHANGE THE DRYING SETTINGS: NOTE: The settings cannot be changed while the dryer is running or paused. The dryer must be in standby mode (power is off) to adjust the default settings.

1. Before starting a cycle, touch and hold DRYNESS for 6 seconds.
2. Touch DRYNESS to select the dryness level shown in the time display: 0, 1, 2, 3, or 4.
3. Touch START/PAUSE to save the new dryness level setting.

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.

the limit switches are known to go bad on dryers

check the vent probly cloged or vent hose kinked, or heater is broken.

After 25 years,your automatic sensor may be bad. RepairClinic.com might have one. Clean everything inside while you're there.
