Any hvac techs out there? Just replaced a control board and it's not working. Main fan doesnt come on. I've probably screwed something up but I cant find it. It's a york unit, single stage using a universal board white Rodgers 50m56u-843.
Fan relay comes on when I jumper thermostat connections. Heat goes through the motion but gas never opens.
Gonna drop 30 degrees overnight and I've been at this 5 hours. Shouldve been an hour tops
