Hey there. I am new, so don't be too hard on me. My ac went out recently. The display on thermostat is still on, but that is because the batteries are brand new. I checked the circuit breaker and that seems fine. The power switch on the furnace is on as well. So, after reading a bit online, I took the cover off the thermostat to see of the wires had any power. I touched the red to the yellow and the ac turned on. SO, I figured it was a bad thermostat. I replaced the thermostat and still nothing. So, I tested the wires again, but now the ac wont start at all when I touch the red to the yellow. I don't know the issue is but I worry that I shorted something out. At least I feel the thermostat was actually bad; however, I think I caused a bigger problem. Any help is appreciated.

Chances are if you shorted some wires, that the fuse on the furnace control panel is blown.
Take a look at the board, they generally use automotive type fuses. You should be able to visually see if it's blown.
