How to Replace Extension Springs on Your One-Piece Garage Door?

Understanding the Basics of Extension Springs

Replacing extension springs on your one-piece garage door is somewhat different than replacing torsion springs. While there is a bit less danger involved, it is still important to treat the task with respect. Retail hardware stores like Lowe’s and Home Depot typically carry these extension springs, but their availability may vary based on your location. For instance, one-piece garage doors are less common in regions that experience heavy snowfall, as they can be challenging to operate under such conditions.

Identifying the Right Extension Springs

The most common extension springs for a one-piece garage door are manufactured by Holmes Co. You can identify them by the orange tag that has the spring size stamped on it. The typical size is 728C, where ‘7’ indicates the coil wire size and ’28’ signifies the length of the spring. An average wood one-piece garage door, such as a two-car garage door, will often have four of these springs—two on each side.

Preparations Before Spring Replacement

If you decide to change the springs yourself, there are some crucial steps to follow. First, ensure that the garage door is completely open and supported with a 2×4 to hold it in place during the spring replacement process. If you notice that a hinge is detached from the wall, avoid operating the door as it can lead to serious injury.

Seeking Guidance and Education

There is plenty of valuable information on YouTube regarding the replacement of garage door springs, whether they are torsion springs or extension springs. If you are new to this type of work, educating yourself about the process can be beneficial. Remember, safety is a priority when dealing with garage door springs.

Ensuring Proper Matching of Springs

When replacing the springs, it’s vital to match the new springs with your old ones precisely. Mismatched springs can lead to issues with the garage door’s opening and closing mechanism. If you find this task overwhelming, consider hiring a professional garage door company for the replacement of extension springs.

Cost Considerations for Spring Replacement

The cost for changing extension springs on a one-piece door is usually not prohibitive. It may be wise to inquire about the cost to replace all of the springs, especially if one has already broken, as others may follow suit relatively soon. It’s important to weigh your options wisely before deciding.

Safety First: Ensure Help is Available

Finally, always prioritize safety when working with garage door springs. Try to recruit a friend or family member to assist you with the project. Having an extra set of hands can make the process smoother and safer. By treating the springs with respect and taking necessary precautions, you can effectively replace your extension springs.

Frequently Asked Questions

We receive many calls involving the safety eyes preventing the garage door from closing due to the safety eyes malfunctioning or simply being out of alignment. If your garage door opens fine, but will not close using the wall console, then this could be a safety eye issue. If the opener light flashes and/or the motor makes a clicking sound, this is a warning that you have a safety eye issue. You can begin by looking at the safety eyes themselves. You should see a steady light on both of the safety eyes. If one of the lights is flashing then you may just need to simply align the eyes properly. This is done by physically moving/adjusting the safety eyes until you have both safety eyes with a solid light showing.

If both safety eyes are showing a solid light, then you may have malfunctioning safety eyes.

A simple test is to press and hold the wall console to close the door. If the garage door closes while holding the wall console button, then you probably have a safety eye issue.
