The odds are the hi speed fan wire is off the Roof AC control board if the hum is the compressor and not the fan motor. Open the roof AC filter cover and you will see the tstat wires to the control board, just look and see if one spade terminal is not connected. Doug
Bingo Doug! Took off the filter cover wiggled the high fan wire and boom, fan came on. Didn't spend enough time to see if it's the crimp on the spade connector or the connector itself. That'll have to wait till the weekend.
Thanks all for your advice.
