When running the dryer on the dryer sensor mode - normal, heavy duty, delicate - the dryer timer will run for a few minutes, example 53 mins, and then will operate normally for the first three minutes and then jump to 1 minute remaining and then do the normal cool down and shut off.

I can run it on the, Manual side, and it operates and drys just fine.

I am hoping to find out what the part or parts I need to replace.

Thanks so much for any assistance!
