Help Troubleshoot ac wont turn on

I was doing some siding on my house, so I pulled the box off going to compressor. Put it back on and went in house to turn on ac, honeywell thermostat is blank. I measured 220v at the box going to compressor. The only other thing I touched was the refrigeration tubes that run along side of house up to attic, I pulled the shroud off that goes into soffit. Any ideas? Thanks in advance.

There should be a thermostat wire going to the condenser as well. Its possible the wires got snagged and shorted and blew a fuse in the air handler or furnace, or a bad transformer if it wasn't fused.
If there's a circuit board in the indoor unit, look for a spade fuse (a car fuse) in the board. But find and repair the short first.0 -
If the stat is dead, that sums it up. Batteries?It’s possible you grounded the 24v and blew the tranny or fuse on the indoor system (furnace/air handler)
kinda depends of what caused the stat to bite dust0 -
I went up to the airhandler and took the cover off, couldn't find ny fuse. I started poking around by the circuit board and the thermostat come on. Not sure what happened or how there was a problem at the air handler , but it works now.
Thanks for the replies.
