Garage door spring broken!

Question

does anyone know how difficult it is to change a garage door spring and how do you do it?please help!

Answer 1

Changing the spring isn't that difficult.  You'll have to do a little disassembly to remove and replace the spring.  Once it's back together you'll have to "load" the spring before tightening the bolts that secure it.  Loading the spring is what what helps lift and lower the door.  Loading the spring is simply rotating it around the bar it's on until it is tight.  Be careful as you do this because having it slip and unload on you could hurt. I had to help my dad change countless springs until he replaced the old door with a lightweight fiberglass one.  

Answer 2

Get it done . They are dangerous if you do not know what you are doing

Answer 3

Marcy is talking about a spiral-spring that winds on a rod above the door.

If you have a door with a spring on either side it is best to replace both of them as the other one is worn and its' pull will be different than the new one.

Door springs are rated in pounds of pull.  Some springs have the ends color-coded to help tell.   To replace them, they MUST be relaxed, or in their smallest state.   You will want to replace the steel cabling as well.  This can be daunting, as the cables needs to be adjusted just right or the door will bind when opening or closing.

And this can NOT be over-come with a door opener.  If a door binds when opening and closing by hand, it will kick-back with an opener.

A garage door installer will open the door, by lifting on the side with no spring.  Once up- they will clamp it in place to keep it from coming down.  Undo the cables and springs, reinstall new springs, cables and safety cables.  Then balance and adjust.  They will also check for any worn rollers or other parts.

If you think you can handle it, be careful.  It's not rocket science but there is alot of pent-up energy in the springs and people have gotten hurt by them.
