Front derailer stopped retracting onto small ring
So, less than a year old shimano 105. It just got super sticky retracting or springing back into small ring position. I can move it by hand with cable connected and disconnected. But it won't spring back on its own. Cable just goes slack.
I'm 48 and I've never had a front derailer get sticky like this. I keep things clean and lubed. Can't see anything broken.
Not a huge deal, a new one isn't too much $$. But I can't stop thinking about what is wrong. Anyone else ever get this type of situation?

Dowse it in lube while moving it around by hand. It ought to free up eventually. If it doesn't, then you might have had bad enough luck to get one with a bad spring, spring stop, or pivot.

Thanks
Thanks for replies,
Drenched in lube, very clean and spring seems anchored. It'll move by hand but very difficult. It's such a simple mechanism. Nothing looks broken but maybe a pivot pin snapped and I can't see it?? Going on vacation next week so I'll probably throw a new one on today if local shop has one. Thanks again!

Free at last
Took it off bike and just worked it by hand and kept soaking it with silicon spray lube. Back and forth, back and forth until it sprung back. Must have just been stuck. Moisture? Grit? IDK looked fine and clean Strange.
