Kenmore Dryer Auto Cycle

Hi,

I have a Kenmore dryer and here are the symptoms.

Timed Cycle advances and heats as normal, and shuts itself off.

Air Dry Cycle advances and heats as normal, and shuts itself off.

Auto Cycle will not advance and has minimal heat addition…

Can anyone help me with what is wrong causing the auto cycle to not operate properly, but the other cycles are appearing to work just fine??

Thanks for the help!
