I have an Amana dryer that is not shutting off when using the electronic dry cycle. It works fine when using the timer, though. Any thoughts on this?
Here are your parts

Here is a tech sheet

Here is a manual

Could be a number of things but at the the top of the list would be a dirty moisture sensor Item 18 in Section 4. Clean them with either water or isopropyl alcohol or electronics contact cleaner. Be sure they are dry betore testing. Also if using a solvent leave the door open for sometime as you want to let the vapors clear.
FYI
When there is moisture between the parallel metal strips, it provides a current path for low voltage. The board then senses this and does not advance the timer. When there is no moisture then no current and the timer advances. Anything that provides a current path between the strips will make the unit think the clothes are still wet and will continue to try and dry them.
ok, I tried testing the sensor by putting a piece of metal across the sensor and I started the automatic normal cycle, it sounded the beeper 3 times to indicate self-test which is normal, then removed the metal piece after a few minutes, and it worked fine. This has been an intermittent problem, though, when doing the laundry, sometimes it works fine and sometimes it never shuts off.
Intermittent problem is a synonym for tech’s nightmare as every time you try to repair it the unit will run OK.
Here is a bulletin on the moisture control board that may apply

Often an intermittent problem is a bad solder joint or connection but in this case that should stop the dryer before the clothes are dry not keep it running.
I would check the connections from the moisture sensor to the board to ensure there is no dust etc. between them.
Check the solder side of the moisture control board for bad solder joints.
Often a cold solder joint will be a duller gray color.
It may have pin holes in it.
When gently wiggling the componen you can see it’s leg move on the solder side of the board.t
After that I would replace the moisture sensor board but this is just a guess and I hate doing Plug & Chug repairs.
Keep plugging in new parts till the unit chugs along on it’s merry way.
