No Power at the Control Board York Furnace
p3urd14n09501-Original Control Board White Rogers 50A50-241 , I replaced this board with an ICM2808-However I did not install it right, and it shorted against the meatal frame. Blew fuses.
The problem I am having is No power on the Control board- No blinking LED light. I checked the incoming wire and it is hot-so there is power to the Board.
I reinstalled the old board, WR50A50, still no power to the board, no blinking red light.
Could this be the Door Switch-

Thanks for the tip, both of you- I will check out the Transformer this morning. I did install a Fuse Link to prevent damage when I installed the new Transformer, some time in the past. But I will check it. It is also helpful that you send info to me, like the Entire Board runs on 24v, wish me luck ,its cold in Michigan.

Do I check the Xformer at the 120 connection, and then the other upper side for 24v

Why did you replace the control board in the first place? And why did you try to do it without turning off the power?
