well...dunno the technical stuff about the garage door...but we just had both the torsion springs and a new garage door opener installed...
a year or so ago,the rollers on the door worn down...which put some pressure on the springs..got that fixed by installing new rollers.
like 2 months ago..one of the springs(theres two..one on each side..well at least for our door) snapped...got someone to install new set of springs. apparently the springs do rust or if there is a "weakness" in the springs..or too much load on the springs..they do snap...i guess ours were the result of all that.
a few weeks to a month after...garage opener broke...guess too much load from the broken springs(lol...or trying to open and close the door thinking that we just pressed it wrong when it broke)...then again... the machine is old..so it was slowly breaking anyways...got a new one installed.
so..to answer ur question...if u have springs that aren't "suitable"..it might affect your garage opener...but since it's not that old..dun think the spring will be inadaquate...unless the installer of the springs wasn't doing it properly and so on.
another thing could be the garage opener is just "doing business"...like trying to get you to install/buy things for something that isn't important.
if the springs installer did scam you..shame of him/her..cuz it could hurt someone if not installed properly. ask the garage opener installer what they mean by 20lb force and how to remedy it ...cuz it could mean "tightening" the springs or do they mean actually putting new ones in. hope stuff turns out..g'luck
