My dryer will not dry clothes in one cycle!

Those sensor bars can become faulty and that is probably the problem. Try cleaning them off with a clean rag. Good Luck!

Dryer has a moisture sensor that detects the clothes are dry so it shuts off earlier. If the clothes are still damp then the dryer vent may be plugged and causing the unit to run hot or not able to fully evacuate the air from the machine. Clean the vent and make sure it's completely free and try again. If it short cycles again and clothes still damp you may have a sensor controller issue.

Dear Barry,
Try 2 things.
One, be certain the clothes are very dry coming out of the washing machine.
If the washer leaves the clothes wet ( like the belt might be slipping), it can take the dryer forever to finish drying the clothes.
You can tell by hand-wringing them.
You should not be able to get any water out of them by hand-wringing after they have spun dry in the washer.
Two, try running a load with the vent hose unhooked off the back of the dryer.
If this fixes the problem, you are having a "clogged vent" issue somehow.
Be blessed.

Instructions

1. Dryer Does Not Run
   • 1 Close the door firmly. The dryer will not operate if the door is not completely closed.
     
   • 2 Press the "Start" button firmly or push the knob in to start the dryer.
     
   • 3 Turn the dial past the "Off" position and away from "Wrinkle Prevent." The dryer will not start in the "Off" or "Wrinkle Prevent" position.
     
   Long Drying Times
   • 4 Remove the lint screen. Clean it and replace it.
     
   • 5 Check the temperature of the room. The dryer will not operate properly in temperatures below 45 degrees Fahrenheit.
     
   • 6 Inspect the area around the dryer. It requires at least 1-inch clearance on the front and sides of the dryer. A 5-inch clearance is needed on the back of the dryer. Move the dryer, if needed.
     
   • 7 Separate large loads and do not use an air dry cycle.
     
   Lint, Stains and Wrinkles
   • 8 Clean the lint screen before drying each load of clothes to prevent lint buildup on clothing.
     
   • 9 Add fabric softener sheets before starting a drying cycle. If the sheets are added after the load has partially dried, they can leave stains on the clothing.
     
   • 10 Dry small loads and remove clothing as soon as the drying cycle completes to prevent wrinkling.
     
   Dryer is Noisy
   • 11 Check the inside of the dryer for loose change, buttons or other items. Empty the pockets on clothing before drying.
     
   • 12 Separate items that are knotted together and restart the load. Knotted or balled up clothing will bounce and make the dryer vibrate.
     
   • 13 Level the dryer. Turn the leveling legs on the front of the dryer clockwise or counter-clockwise until the dryer is level. Turning the legs clockwise will lower the dryer. Turning the legs counter-clockwise will raise the dryer.
     

This problem may be the result of a dirty lent filter which if clogged will short cycle the dryer and the clothes will still be damp when done. Also a dirty exhaust pipe (usally 4") will prevent the clothes from drying correctly. Make sure that the air is leaving the machine. To do this you have to go outside when the machine is running.

sounds like an air flow problem meaning the dryer is not exhausting the hot air. Best way to check is to disconnect exhaust tubing from dryer and run a cycle. If the clothes dry normally the vent to the outside is plugged. Hope this helps

I am having the same problem on a WD9900A. The wash cycle works great. Spins fast and clothes are completely rung out. Dryer cycle heats up well. Fluffs and heats cloths. At some point during dry cycle water is injected on clothes and they end up sopping wet; much wetter than after wash. Filter is clear. Outlet pipe clear and functions well. Possible problem with dryer timer? Or washer timing kicking back on?

Sounds like your problem could be the thermostats or the heating element, they will normally cause the dryer to take a long time to dry the clothes

if the clothes are warm after the cycle then you need to make sure the vent to the outside of the house is not plugged if they are not warm then it is in the heating circuit of the dryer wether it be the element or a fuse will have to be tested. to dry clothes it takes heat and air flow if you dont have one of the two they will not dry correctly

Replace the timer.
