Am Standard Freedom 80 Furnace Fan Motor
 
The other night, the circulating fan was humming, trying to start.I have replaced the fan motor on the squirrel cage and the capacitor. Now, when I have a call for AC, the only fan that turns on is the inducer fan. I'm beginning to think that we had a surge that may have fried the board.

Any ideas?

ensure it is wired properly... check for voltage at the cooling blower tap on the control board with a call for cooling from the stat.
