This is a good thing... I have to admit....when I started testing my "Tanks" it was tedious to say the least. Yes, all the material on the schematic checked out, all the wiring/routing/connections were spot on....but until ya flip the switch and things happen like they should you never know..... I wired up a draft fan, room fan and an auger motor to the control and ran it through its paces for weeks before I was happy that the design was ready for prime time. Still, there are components in the box that I have no control over as far as design and production goes. The company that made the parts caters to industrial customers and they have a very good reputation for quality. Yet I still felt uneasy about handing over my warm house to "Strangers" ya know. But on the other side of the coin was the price of "Factory type" replacements from a few aftermarket manufactures (My stoves are 92 model year) and Whitfield is long gone.. The replacements all use the last factory specs to reproduce the boards. You are lucky to have new parts available from a reputable manuf.
And you are lucky that you have the knowledge and ability to make a new board to your liking. Kudo's!
I was a master mechanic for Oldsmobile then a firefighter/mechanic until 1984. I took a job with a large manufacturing company running their vehicle shop then moved into their power plant for ten years until my medical issues. Throughout my careers I became confident that there is nothing I can't do...with the exception of making my own circuit boards! By the way, I can confidently say that the stove is fixed. Been working perfectly. *phew!*
Glad the stove is off the sick list. You can buy "Kits" to etch your own PC boards. I have messed with that stuff a bit. I decided to go HARD WIRE old school.
