DIY steps
- Before starting, close the garage door, disconnect power to the opener, and wear gloves and safety glasses. Never loosen the bottom bracket or any cable hardware, because it carries lift-cable tension.
- For an upper or middle roller only, use the manufacturer-approved procedure with the door secured and the tension system untouched. If the damaged roller is in the bottom bracket or the procedure is unclear, stop and hire a garage-door technician.
- Carefully pull the old roller out of the bracket and discard it. Take the new nylon roller and insert it into the bracket, ensuring it's properly seated and aligned.
- Reattach the roller bracket to the door track using the screws you removed earlier. Make sure they're securely tightened to prevent the bracket from coming loose over time.
- Test the garage door by opening and closing it several times to ensure the new roller is properly seated and functioning smoothly.
- Clean up any debris or tools and dispose of the old roller responsibly.
