Matthew Barnes-Homer's late header earned Luton a replay against Blue Square Bet North Corby Town.
The home side took a shock lead early in the first half when Ben Mackey headed in Danny Pitham's cross.
The Hatters dominated the game throughout with Claude Gnakpa hitting the woodwork and Fred Murray firing narrowly over the bar.
Barnes-Homer grabbed a deserved equaliser with seven minutes remaining, rising highest to nod into the net.
Corby Town manager Graham Drury told BBC Radio Northampton: "They put us under a lot of pressure. We defended well for the majority of the game but I still believe that if we can use the ball well we've got a real chance in the replay.
"You give Ben Mackey the service and he'll score. I'm proud of the boys but disappointed not be secure in the next round.
"The Luton players haven't got to go and lay bricks, they haven't got to wheel bins or wire plugs. I wouldn't have taken 1-1 before the match as it's going to be harder now."
Luton Town manager Richard Money told BBC Three Counties Radio: "Job done in the end, we're still in the hat.
"I can't tell you how poor the pitch was and in the end I thought we got just rewards for our brave endeavours.
"We virtually played with two at the back for 80 minutes and it was a tough afternoon."
