MY york furnace wint do anything. YOu can switch the fan to auto and it won't even come on. It has power to the thermostat. If you hold that ignitor button in for a while it will light up and kick on but when you let go it just shuts off. Is there a blower reset button or a reset button for the furnace somewhere. I have troed everything with this thing. Changed the heat sensor , thermostat, don't know what is wrong with it.

I would start with double checking the thermostat wiring to ensure you have the wires hooked up properly. If that is not the case Then the board is not getting power or sending out a signal to the loads. I would also look for a fuse on your control board.
