I just refinished my hardwood floor in my kitchen. I rented a sander at Home Depot and sanded it twice and then put on 2 coats of stain and then 3 coats of oil base sealer. In between coats of sealer I sanded the floor with a brown paper bag (the guy at Home Depot told me to do that). I let the last coat of sealer dry for 4 days and on the forth day I moved my fridge back into the kitchen. I put towels under the wheels of the fridge to try and cut down on any scratches. Well I think the towels made it worse because the wheels dug into the floor and left these gouges in the floor that are about a 1/4" wide by 4 feet long. I tryed to re-stain the gouges but it just doesn't seem to be working. Does anyone have any idea on how to fix this?

It will need to be re-sanded. The weight of the refer crushed the wood floor fibers. In the future, use a dolly and roll it over plywood or masonite. There is no other repair that will restore crushed wood fiber.
