Product review (4 stars): Fixing Dryers and Saving Souls/First Borns
I had the evil maniacal blinking lights issue as well.  My supplier wanted to charge an arm, a leg and my first born for the replacement part.  Checked here and found it at a much cheaper rate where I still get to keep my soul.  Replaced it myself (it's really not that difficult)...

My dryer has a new lease on life. It works like new (except for the coin stuck in the drum).  I only gave it four stars because WHY ARE DRYER CONTROL BOARDS SO FREAKING EXPENSIVE?!?! I swear if the part breaks again, I'm going to hack an raspberry pi to run my dryer. $35 vs. $150ish.
