Moen Shower Valve is stiff.

[Barry J]

I had my Moen shower valve replaced less than a year ago.
The plumber had set my temp setting a little too low.
A couple of weeks ago I adjusted the plastic settings to be a little hotter.
Now I am noticing the handle does not turn as "freely" as it should.
Especially towards the hotter side. It does not bind up yet, but want to fix it before it starts.
Did I go too tight on the center screw, or something else need adjusting?
Any suggestions?
Thanks
Barry

The "tension" is internal and nothing you can do will make it more or less tight. The only way you can change it is to replace the core unit.
