The instructions aren't for sh*t. I can't believe a Home Depot sells
amateurs a 220 V recepticle with practically no instructions. So anyway,
I've got the dryer working by switching the white wire from ground to
neutral, the red and black are hooked to what I would call "hot" as they
both produce juice on my tester. So if it works, and it was only three wire
before (17 years), should I be concerned?
