Most likely low pressure lockout due to extreme cold. Happened to me many
Times. Even technician said people would put paper clip across reset pins on control board in winter. Take the cover off the outdoor unit and should see control board that should tell you what the two lights blinking mean. If resetting a few times doesn’t help then you may need to have it checked out. I had to reset my outdoor unit almost daily in the really cold winter couple years ago.
