Hello! Thanks so much for reaching out to us. I'll do my best to answer your question.
The trickiest part about replacing your Andersen screen door wheel assembly is removing the broken roller. These are removed and installed through a hole in the bottom of the screen door frame. To remove the old roller, you must try to squeeze the clips on both sides of the roller and pull the wheel assembly out of the door frame. Sometimes the clips break, which allow you to easily pull the old roller out.
To install the new roller, you need to work it into the door frame while rotating it to allow the adjusting bar to fit into place. The diagram below should hopefully clarify what I mean. The new roller will snap in when pushed all the way into the door frame. After the new roller is snapped into place, use a screw driver to adjust the wheel height via the adjusting bar.
To adjust the 84-070 screen door roller, you'll want to turn the long spindle that comes out of a hole on the side of the patio screen door.
If you turn that spindle and finds that it's not adjusting, then it may be stripped. Replacing the entire roller assembly is your only option in that scenario.
Yes, I think I agree with your assessment. In your case, replacing the entire roller assembly seems to be the most viable option.
That's great to hear! I'm glad everything worked out for you.
Please feel free to reach out if you ever needed anything else. We're always here to help.
I used a small flat head screwdriver to push the tabs in and then gently pried them out on both sides and then was able to work the old wheel assembly out. Mine lasted about 16 years and now the wheels have all broken and the adjustment is not able to be made without removing them. I am trying to find a store in my area to buy new ones from the only one I found in Saginaw
