    Well, without further ado, here are the different things you must do if you want your opener chain problem solved.

    1. Identifying the Problem

    The first thing you need to do to solve any problem is to identify exactly what the problem is, and the same thing should be done in order to fix your broken garage door chain.

    Check and see if your chains are repairable or if it needs to be replaced with a new garage door opener chain.

    Identifying the problem will also help you decide whether you can handle the problem and proceed with fixing it or if you should call your local garage door repair company to help you out.

    Depending on what the previously assessed problem is, proceed to fixing or providing a solution for it.

    With your garage door opener chains, there are only two things about it that will affect your door’s performance, either your chains are broken or just showing signs of damages that can be repaired.

    If it is broken, then there is no other way but to have it replaced with a new one.

    You can purchase a replacement garage door opener chain from your local hardware, your opener’s supplier, or by consulting with your local garage door repair company.

    If the chains are only showing signs of damage that can easily be repaired like rust or corrosion, then proceed with dealing with it accordingly.

    Rust can easily be removed by applying lubrication on it to loosen the rust that has formed on the chain’s surface.

    If the corrosion seems to be worse than initially thought, you may try submerging it in lubrication for a few hours in order to loosen the rust then wiping off the loosened rust with a soft fiber cloth.

    3. The carriage of your garage door opener should be clean

    Once you are done dealing with the chain, proceed with cleaning the other components which might have some rust rubbed off on them.

    One of these components is the carriage of your garage door opener.

    This part has the most contact with your rusty garage door opener chain.

    In order to prevent it from rubbing some rust again on to your previously cleaned garage door opener chain, make sure you clean this component as well by applying lubrication on to it and rubbing off any rust residue on its surface.

    4. Reattach your garage door opener chain to your garage door opener

    Once everything is cleaned and rust-free, it is now time to reattach and reassemble the previously removed components or parts.

    Put everything back in place as it should.

    5. Checking your garage door’s functionality

    Lastly, once all is done and returned to how it should be, it is now time to have your overhead garage door tested.

    Check and see how your door is working after having fixed the problem and if the problem is indeed repaired.

    If your garage door functions well and fine, then this means that you have successfully completed the job at hand.


    Without your garage door opener chain, your garage door opener will lose the ability to open your garage doors for you.

    And this is why your garage door opener chain is a very important component of your garage door used in lifting it open and close.

    As long as you follow these procedures properly, you will be able to deal with your faulty garage door opener chain.
