It was time for my monthly 2 hour generator run so I pulled the fuse labeled "furnace" and turn the break off for the AC unit then back on.
There was no other fuse labeled anything heater related
Didn't think the furnace fuse had anything to do with it but now the AC unit is working. Must have been turning the breaker on and off.
thanks for the suggestion!
