Kenmore He5 Dryer

The load is dry, yet the dryer keeps running and running. Before that unnecessary heat damages your clothing and drives up your utility bill, you may need to replace the timer or the electronic control board that isn't ending the cycle. If your dryer uses a mechanical timer and doesn't stop when the dial reaches the off position, then a failed contact in the timer is likely causing the dryer to continue running and you'll need to replace the timer. If your dryer uses an electronic control, a stuck motor relay on the electronic control board can cause the dryer to run constantly with the dryer door closed. If the dryer stops only when you open the door, you'll likely need to replace the electronic control board.
If the dryer won't turn off when you open the dryer door, the dryer door switch likely failed. Replace the door switch if it doesn't accurately detect the door being open or closed.
These tips can help you figure out what's wrong when your Kenmore or Kenmore Elite dryer spins when off. You can also use this repair help to fix your Whirlpool, Frigidaire, Samsung or LG dryer that runs when the control is in the off position.

Does it drip just when the unit is operating or do you find water in the machine when it is not running? Try shutting the water off to the dryer and see if the dripping stops. If it does the water inlet valve needs to be replaced.

CHECKS UR THERMOSTATS AND UR VENT LINE FOR CLOGGING. MY GUESS UR CYCLING THERMOSTAT OR THERMISTOR

If you hear a humming/clicking sound from motor area you more than likely have a bad motor.
Try this test out to see if u have weak windings or relay on motor.
Open the dryer door and turn by hand the drum while machine is on ON position. And you or someone else presses the door engagement switch in. If it starts up then u have bad windings OTHER WISE CHECK FOR A LOOSE WORN BELT

change the gas coils on the gas valve by removing the 2 screws holding the bracket for the coils,remove the wire harnesses to each coil,dont worry one coil has 2 wires the other has 3 so quite hard to reverse

Unplug it and check the connection inside where the cord attaches to the machine. I have seen these come loose.

Try putting less of a load in dryer. The weight of the clothes riding against the door, may be the reason why it pops open.

I had this same problem with my Kenmore dryer. If I left it plugged in and door shut it would eventually turn over and start up again. But now my timer is working properly but my dryer won't heat up and dry the clothes. I need help....

Chances are the little plastic latch keep is broken. Look at the door and locate a peice that will press into the front area where the clothes go in.
Once you see it, check the keeper and see if it is broken. The door should not just pop open.

check to see if you have bent door hinges first, do this by opening the door all the way down and see if it is level with the floor. if it goes past level then the hinges are bent.
guess someone may have fell on the door or used it as a step.
if so, then you can take a hand towel and roll it up, then put it at the bottom of the door and close the door gently to "bend" the hinges back into place. this will aloow the door to stay closed and should also take care of the "burn" marks on your clothes.
i would guess the unit was overheating from the door not closing right allowing air to enter around the door. that will cause the unit to overheat and leave marks on your clothes.
