Garage door cables lift the door and counter balance the springs. In an extension spring system, they run on pulleys and in a torsion spring system they roll into a drum at the top of the door. There are many reasons garage door cables break but a here a few common ones.
1. Cables are rubbing against the track or other garage door hardware.
2. Moisture caused the cable to rust. Usually, moisture occurs at the bottom where water from rain or snow seeps in the garage. However, if you leave the door open during these weather events, the cable can rust anywhere.
3. The pulley could be splitting somewhere and causing the cable to fray. Invest in cast iron pulleys which are resistant to splitting.
CAUTION: Garage doors are a very big moving object and their parts balance each other out so that minimal work is required while moving. When one of the garage door parts break, it changes the system. If you try to lift the garage door while the parts are broken, you could be causing injury to yourself or damaging the other garage doors parts.

I find it alarming that leaving your garage door system exposed to moisture could end up causing rust to its components, such as its cables. My uncle is thinking of having a garage installed on his home so that he can store his new sports car with ease. I'll be sure to share this with him so that he'd reach out to a garage door expert when this happens.
Thanks for helping me understand that moisture can able cause rusting which would affect the cable's integrity. I guess that is the reason why I need a garage door repair now after living on this property for almost a decade now. It's because the location we are in can be quite humid most of the time due to the changing weather almost every week.

My garage door cable broke, and I'm not sure what to do about it. It makes sense that replacing the cable might not fix the underlying issue. It would be smart for me to get a professional to help me out with figuring out what the main problem is.

Thanks so much for explaining why a garage door cable might break. My brother's cable broke a few hours ago and we can't figure out why. We'll have to look into calling a professional to come down to assess the damage to everything and hopefully fix it all soon.

It really helped when you talked about how the pulleys and torsion springs would run the extension system in the drum at the top of the door. I guess it will depend on the type of material you have if you already need a garage door spring repair this time. I should talk to a professional because we have been having issues in that aspect of our home after living here for a decade.

Thank you for mentioning that the cable might corrode anywhere if the door is left open during certain weather occurrences. My sister's garage door has rusted due to rain and moisture. I'll contact the garage door repair business and advise her not to open the door during inclement weather.
