Several years ago the sensor dry function stopped working in the dryer, but we were out of warranty so we just switched to the timed dry function instead. Now, the timed dry function does not work either. When we turn the unit on and select a timed dry (20, 30, 40, 50, or 60) it *usually* starts right away (though increasingly it will just "click" and go immediately into the wrinkle care mode) and then seconds later stops drying and goes into what looks like the "wrinkle care" mode. The unit stays powered on and the LED display is circling, similar to when it is in the wrinkle care cycle. After a minute or two, it will cycle back on (actively drying the clothes), only to stop again after a few seconds. Each time it cycles off (stops drying) we hear a clicking sound.

I've tried unplugging the unit to get it to reboot, but that does not work.

What do I need to do to attempt a repair?

Thanks in advance for any insight or advice!

These driers will do that when the lint builds up like concrete on the inside of the air ducts. Halfway doing it will not work. You need to totally tear it down and scrape out and wash all of the parts except the motor, which you vacuum out. You can go to YouTube to see videos on how to take it apart, but do a very good job or it will fail again quickly. I would get a new belt and change it while you have it apart and get some white lithium grease and grease any bearings you find. You need to clean out a drier every two years, at least, according to the manual. You just unplug the wires from the sensors and remove ductwork that they are attached on and clean the entire thing with soap and water. Make sure you go all through the dryer and get all parts like the blower fan and housing, vacuum out motor well and clean exhaust. Mark all wires you unplug so you know where they go. This is an easier job than you would think. My sister does hers at least once a year since she has five children and the dryer gets a lot of use. This is an easier job than you would think.
