Moen Shower Knob : Screw Won't Come out
Jeffy3
on the water and turn left and right for temperature control. I
believe the knob is broken as it turns completely around but doesn't
change the temperature. When I pop off the cover I get the screw to
turn and turn but it never completely comes out. Any thoughts?

Sounds like it might be possible that the shaft is spinning.
Sometimes you can slide the cover under the knob back and see the
shaft. You may be able to drill the screw head off. Otherwise you
might have to carefully break the knob so that you can remove it from
the shaft. Moen has a lifetime warranty on most of their stuff. But
it will be a lot easier if you can fix it without simply replacing the
whole thing. Unless you can get at it from behind.

What makes you think that? :-)

Anyway, as Jamesgangnc mentioned, it might be possible that the shaft is
spinning.
Another possibility is that the screw is stripped to death or broken off.
Gunk may be keeping it from falling out easily. Try a magnetic screwdriver,
telescoping magnet, small needlenose pliers small pickup tool to grab the
head.

Thanks for the answers. If the shaft is spinning is that another
problem to be worried about? Does the fact that I can change the
temperature of the water by turning the screw help with diagnosing the
problem, or is that to be expected? If I break off the old knob,
won't I still be unable to get a new one on without getting that screw
out?

Yes, that does change the diagnosis. It sounds like turning the screw
is operating the valve as designed. The problem is likely that the
plastic ribs or flat spot inside the knob is stripped out causing the
knob to simply spin on the shaft. You need to get the plastic knob
off and without seeing it it is difficult to advise you. I think that
if you can get the knob off then you should be able to grip the metal
shaft with some pliers and then loosen the screw.
I don't know how you can get the knob off except to break it. A very
small chisel applied to the knob plastic around the screw head
perhaps? Or a cutting bit in a dremel? Just some thoughts.

My thoughts also. Use Dremel or a hacksaw blade. .Cut into knob a ways and
then stick a screwdriver into slot and twist to crack knob and remove. WW

Thanks so much. When I get home I will try this! BTW, it's the
teardrop shaped knob.

Pull out on the knob as hard as you can without breaking it while
turning the screw out.
If it comes apart and a new screw works you are OK, if not you need to
replace the shaft.

I would not expect that to work. The shaft is spinning inside the
knob. There is a remote chance that pushing the knob sideways while
turning the screw would work.
Moen will send a free knob if you can figure out the model number and
tell them you are the original owner.

Try pushing in hard on the knob. If the knob will push back on the
spline, you may be able to hold the knob inward (holding the shaft
spline) and gently back the screw all the way out. Only then pull the
knob off.

Guess I got that backwards. I thought the shaft only turned as far as
it normally would from hot to cold and then stop... then the threads
were stripped and wouldn't come out with forward pressure on it.

The OP might be able to grab the shaft behind the knob with a small vice
grip or other type of small pliers, and remove the screw.

I have exactly this same problem, but I don't see a successful resolution to
this problem but many ideas to get the wheels in my mind turning.. . One
thing I did try was pulling hard on the handle while turning the screw only to
realize I didn't turn the water off first. Will be drying off tonight and
trying again.

This is an old post, but I have an answer for those who come after me. It
really helped me to find the problem wasn't just me. Okay, so basically the
screw is screwed into something that turns behind it. When you think you are
turning the screw, if it's corroded, chances are you aren't - you actually are
turning the thing behind it. It's a no-win situation. That screw is never
going to come off. Here's what I ended up doing. Some variation of this is
probably what you need, depending on the tools you have on hand. I took a
Dremel tool and sliced the head of the screw off. Then, I slid the plastic
faucet handle off. Now you can actually see the problem. You can also slide
the other parts behind that easily slide off for better access. You see a
piston like thing. I have a small vise that latches on to a table. I took it
off our workbench (it's relatively small) and clamped that thing on to the
screw really tight. Then, I took pliers or a wrench and held the piston thing
firm so that it didn't twist and unwound the screw with the vise. Plenty of
trial and error and cussing, but this method without the error and the cussing
worked like a charm, albeit it was never what Moen would recommend. Good luck!

Curious if you needed to replace the cartridge as well as the knob? I had a
similar issue but am hesitate to slab a new knob on if it wasn't the core of
the issue.

I have a pull out Meon shower devise. I took off the middle insert but
can’t get the screw to turn. The reason I’m wanted to get it off is to
clean the knob. It has black stuff inside the knob and I want to clean it.
Any ideas???
USAcourts.com
been on there for along time. It’s just like a knob in the bathroom when it
breaks. You pop off the middle and unscrew it and replace it.
