Paul Brayson grabbed a hat-trick as Northwich surprised Morecambe.
He opened the scoring after 19 minutes when he rounded goalkeeper Ryan Robinson to slot home.
Brayson doubled Northwich's lead four minutes before the break as Morecambe failed to clear a corner and the loose ball was fired home.
He then curled home his third after 67 minutes, and there was no consolation in Danny Carlton's late strike for Morecambe from Michael Twiss' pass.
