Ran the Aprilaire test procedure and found out I had a bad relay. Bought a new board.I also bought a new relay to fix the old board as a spare. At first I thought the water solenoid was bad since I was not getting any water. So I replaced that with no luck. Come to find out there is an orifice in the water line after the solenoid that was clogged. I had hard water and recently added a water softener to the whole house. So the orifice should remain clean.

I will come back here for any future parts
We had our 2014 Aprilair 800 smart Humidifier stopped humidifying, caused by the water never shutting off (Fill valve). I am a knowledable DYIer and went through the various troubleshooting processes that determine that the control card was at fault. We bought the card from Supplyhouse.com, received it right away. I carefully unplugged each connection on the old card one at a time and connected it to the new card and buttoned up the box. My wife and I could tell right away that it was working properly by the sounds it was making. We were relieved as everything is back to working again
