Product review (5 stars): PCB.... pretty certain it's bad.
It's a PCB assembly that's ensconced in some sort of plastic resin. If you need this part, well, here it is. If your GE Harmony dryer stopped working, screen doesn't turn on, etc you most likely need this part. Make sure though that you've checked the switches and thermal fuses since they're significantly cheaper to replace than this part.... if they are the culprit, you've just wasted quite a bit of money for a part you didn't need.
