Hello,

In our secondary bathroom, our shower/tub has a single handle knob and when turned to HOT no hot water comes out at all and it just shuts off the water (it drips just a little bit when on full HOT, and that water is also NOT HOT). It is a condo unit and it used to work just fine and this particular shower has seen very little and infrequent use. All other faucets work perfectly fine in the condo.
What do you think the problem is and how can I fix it myself? Thank you for any and all help!

-Mike

Do you have a plumbing shop in your area that deals with DIYers? These guys are knowledgeable about the products and are very willing and able to show you what to do. You may occasionally find a "smock man" that can do this, but usually at a Box store you just find sales people. Actually, once the cover plate is removed, you should be able to pretty well figure out what to do next.

Not sure if there are any plumbing shops in my area for DIY'ers, but I could look into that. My next question is, do you have any tips on how to remove the circular plate without damaging the shower wall? It appears that the outside edge (all around) is sealed al to the shower wall with some calking or something similar. Forgive me for the cautious newbie question :).

Take a sharp razor knife and gently cut around the silicone at an angle so that the blade is cutting in towards the valve under the plate. This way you'll avoid damaging the surround.
 
You may find it very easy to turn a small job into a big one...
There is a nut that holds the cartridge in that if it is hard to remove and you twist too hard you can ruin the valve.
