TRANE Central Air unit not working

we turned on our central air and a few hours later, it went off...the thermostat (TRANE) was blank.
Checked the ciruit breaker and it was fine. Any suggestions? PS---The Bypass Humidifier would not stop running about 1 month ago, so I unplugged it from the furnace. Could THAT have anything to do with this? Any help would be appreciated. NJ will be hitting almost 100 today

check low voltage fuse in furnace or air handler on the control board.

open the indoor unit and look for a control board and on the board should be an automotive style 5 or 3 amp fuse

FOUND THE FUSE, but...

How can I tell if the fuse is blown? It seems fine...the Z shaped wire is in tact. Your responses are so very much appreciated! A bit steamy here and don't have $200 to have someone come out to fix this thing. I feel a little more in control with your advice. thank you.

you can check resistance through it. Or go buy some from the auto parts store (inexpensive). To go much further you will need to have and know how to use a multimeter.
