Wink Symmons temptrol shower valve problem?

I have a Symmons "Temptrol" model A shower valve in my shower.Iam not getting good hot water.There is very hot water throughout the rest of the house including the sink near this shower.
The web site said for this problem to take the valve apart and soak it in vinager to loosen deposits,as well as tapping it to free its movement....
I did that,and it seems alittle better,but still not real hot.Any ideas on getting hot water out of this unit?Thanks.

The word Temptrol leads me top believe that this may be an anti-scald fixture. They NORMALLY have an adjustment inside to pre-set the hot water so there is a high limit to keep kids from getting too hot of water. Check to see if yours has a built in adjustment. Good luck.

Limit Stop Screw

Are you familiar with the "limit stop screw" on the Symmons Temptrol?
Have you tried to loosen that screw.
If you have screwed in too tight it will prevent you from making the water hotter.

Check out this PDF.

It has a diagram to show which screw is the limit stop.
Page 1 also has the instructions about the limit stop screw.

"IMPORTANT: After completion of installation step 4, follow these instructions to set the Temptrol Limit Stop Screw. This valve is equipped with a limit stop screw to be used to limit valve handle from being turned to excessively hot water discharge temperatures. To adjust, remove dome cover, open valve to maximum desired temperature and turn in limit stop screw until it seats."

either the limit stop needs adjusted or the cartridge needs replaced

i had the exact same problem as others mentioned. over time i had to turn the handle further and further to get hot water - and the time came when it was turned all ther way(360 degrees) and all i got was lukewarm water. changing the spindle(cartridge) not only solved the hot water issue, it also vastly increased my water pressure. it took me less then 15 minutes to replace the cartridge and i'm a novice when it comes to plumbing. make sure water is off and turn handle about half way(to prevent damage to cap) before starting. remove handle - remove faceplate - remove cap(spindle will come out with cap). unscrew spindle from cap and replace with new one($36 at home depot - part # TA-10). reverse steps above to reassemble and you're done.
