Maytag Neptune dryer, model mde6700ayw, cycle selector knob will not change cycles. It gets stuck on a random cycle even when I power off, power on. Tried to put in service mode but as the cycle selector knob won't turn, I cannot get an error code. I can physically turn the knob, it's the cycle that won't respond to the turn. Then randomly, it will start working again.

Unplug the unit and take off the cover where the cord goes in. You may have one burnt wire under that cover.

It sounds like the element shorted out and caused more damage to the unit. Remove and check the heating elment, thermal fuse (located near element), and timer. The timer will be hard to test if you don't have a meter. I would suggest that you check the element first. This is probably your main problem.

After trying the Fixya posted and LG service recommendation of pressing the pause/play button for 5-8 seconds and unplugging the machine for one minute before plugging back in (which didn't work) we unplugged it for over an hour and the computer reboot/reset itself.

sounds like a stuck or shorted membrane switch.
which would require replacing the console. if you can access the tech guide in the control panel you can do a membrane switch test and other diagnostics.

Yes, you can have a few different issues going on with your dryer and it may be hard to pin down. 1. You may have a intermittent door switch. I've seen this many times. 2. You may also have a motor that is tripping it's overload. 3. You also may have a timer issue. This may be difficult to fix on your own so you may want to call a pro. If it was me, I'd check the door switch or replace it. If it's not that, you may want to consider a new dryer due to the high repair cost. Hope this helps,
