Followed instructions on your video. Did run into a problem when the string came off the new tube.
Pulled it back out through the dispenser end. I then took the old tube, cut the broken nozzle of the end. Restrung the old tube and fed it through the bottom of the door. Luckily, it did come up to the dispenser. I then wrapped more string around the new tube making sure it was taped even more securely and fed it back down through the dispenser. All went well.
I wish that I could have purchased the tube assembly I needed rather than having to purchase a package with two, one being useless to me. It just seems a waste.
I would not have attempted this without the great video instructions shown. Thank you.
Just an FYI, I am a 62 year old female. Have done nothing like this before.
