Moen provides a lifetime warranty and doesn't require a receipt. Just call them and explain the problem and they'll send a replacement cartridge which should solve your problem. Cartridge replacement is pretty straightforward so it should be no problem to do it yourself. The one you have probably has a bad washer.

those are just trim kit numbers those do not show the valve.

No...the (cotter pin) is a retaining piece for the cartridge. If you remove it the cartridge can blow out under pressure.

remove the knob and you will see a serrated valve with a + and - and an arrow or respectively hot and cold and an arrow. Slide the valve off and reinsert it back on with the arrow pointing towards the + or respectively hot side.

check ur anti-scold setting when shipped from factory unit is set cold install instructions always advise about adjusting to suit your comfort--remove handle and using the blue & red adjustment tabs set the heat to your desired comfort

If you remove the handle and the fasia plate you'll see the valve in the center (make sure to turn off the supply valves first. These are located at 3:00 and 9:00 beside the valve. Then the whole assembly unscrews from the center with a large adjustable wrench or a pair of channelock pliers.

It's possible the diverter in the tub spout is jammed.

The problem is most likely with "the back pressure from the flow restrictor in the showerhead causing the spool in the cartridge to sense a false pressure drop. This is forcing the spool to shift, restricting a full hot water temperature from coming out." Believe it or not, I got this information from Moen. Their solution was to send out a valve without the multi settings of the original and that didn't work very well. I can only tell you that I used an older showerhead without the water saver feature and the valve and cartridge worked fine. The problem your having is with the cartridge/showerhead combination and short of using an older showerhead there is not a satisfactory solution. Maybe your plumber has a better solution.

the big round black plastic is part of the installation it will screw to the valve body thats the size of hole the black round cover is also backing plate to round external dress cover so be careful not much leway when cutting the center part should be knocked off but keep on to protect chrome escutcheon take off when applying handle also remember unit is shipped in cold position need to adjust hot water shipped in cold position because of anti-scald system

Most likely the screw in the center of the handle has become loose and just needs to be tightened. Pop off the cover with a screwdriver. and tighten the screw.

Call moen and give them your model no. they will send you a new cartridge free of charge. if you can't wait local stores like lowes will have them. Turn off your main water shut off valve and take off handle, then with some pliers take off brass ring, the cartridge will pull out. First notice the notch it rests in and notice where the hot water adjustment disc is. Assemble the new one the same way, put some vasolene on orings and reassemble. hope this helps.

Faulty control valve. Replace

A blockage or fault has developed in the mixer, most likely the seals have collapsed. Means a strip down after you turn off the main of course.

the diverter is stuck. you have to move it up and down to free it up. the diverter is the mechanism attached to the tub spout that switches the water from shower to tub. you may also need a new diverter if fiddling with it doesn't work.

My husband is a plumber. he says u have the cartridge in on the wrong side- meaning u have to spin it 180 degrees. hope this helps! if that doesn't work then replace the cartridge.

Use little tool (plastic) that comes with new cartridge, in center, and push in and turn with wrench on square end.
It has to bite in to cartridge, and as the cartridge turns, it will start to move outward. You'll see how sleeve where cartridge sits in, is shaped live a "V" sort of, and as the cartridge turns, top and bottom brass pieces of cartridge follows that "V" and lifts itself out, far enough to get hold with pliers, and wiggle and pull. Sometimes takes a little patience, and maybe the odd curse word, but should come out.
