SOURCE: Auto Dry not advancing

It sounds like a timer problem since it happens during timed also. Some dryers don't have an actual moisture sensor for auto dry. They work by knowing that as long as the clothes are wet the temp won't go past a certain point. As the clothes dry it trips a thermostat that lets the timer advance. Until this is fixed DON"T trust the timer to shut off the dryer. Sometimes it won't or could leave the dryer running for hours. This has nothing whatsoever to do with fuses. There are no fuses in a dryer. Just high limit thermostats and other devices that will shut off the heat but usually not the motor.

try replacing the door strikes and catches part # 279570...possible door hinge issue but less likely

SOURCE: during the drying cycle, the dryer door opens

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.

Try this. Set the timer. Open the door, press and hold the light switch. Rotate the drum by hand then while still holding the light switch turn on the dryer. If it starts then clos the door while removing your finger quickly. If this problem persists it could be the starter on your motor.

HI. The timer will be the culprit here. The timer motor is damaged, and the cogs seem to be worn, as well. I recommend replacing this failed timer mechanism. Once replaced, the unit will operate correctly.
