Smoke issue

I have a large stove, unknown brand, and it smokes badly when I open the door. My old stove didn’t do this so I blame the stove, not the chimney. There are no other vents to let air get in except the front door. I found the Tjernland AD-1 auto draft fan that might be a solution but reviews are mixed. Are there any other products or solutions you can recommend to fix this? Thanks
