Product review (5 stars): Fixed issue immediately!
I had already gone through every mechanical/electrical part on my Roper RED4440VQ1 dryer.  Dryer would dry on the timed High Heat setting but still have to run it a few times.  Other settings would turn the drum but not dry in high or low heat at all.  The only part I had not tested was the timer.  I ordered a part at local appliance parts store and was guaranteed to have by Friday after 1 PM.  You guessed it, it did not arrive.  Ordered on Amazon and had it delivered on Saturday for less than the full cost of the part w/o taxes at the appliance parts store.  5 minutes to replace and back in business.  Probably order a few more in the future to have as backups.  This part saved me from buying a new one.  These parts apparently go bad frequently and this dryer was just three years old and in great shape.
