There is no hot water. Period. When I turn on the faucet there is only cold water. If I turn the handle all the way counter-clockwise, the water flow stops completely -- not even cold water. There is hot water in every other sink/shower in the house (including the sink in the same bathroom). This particular shower faucet is not used often (thank goodness) because it is in the guest bath -- but I have a guest coming! Help, please.

Pull the cartridge ( which can be tricky on a Moen positemp), turn on the water for a brief time to make sure you have water coming through the hot port (have someone help you) and then put in a new cartridge.
Let us know how it goes. Good Luck!

Thanks! Trying to foreshadow here... I assume I will be able to figure out how to turn on the water if I have disassembled the handle/plate. What if no water is coming through the hot port?

Moen Posi-Temp cartridge
May occasionally require minor cleaning maintenance, due to debris, situations where there is water with a high mineral/sediment ontent or when
Showers are used infrequently (such as in a vacation home or guest bathroom).

Open the PDF file will show how to remove and clean the cartrdge, Good luck.

Thanks! Hopefully I can manage... :)

You need to change out the cartridge in the valve, it's a Moen Posi temp. Moen will warranty it for free. Call 1-800- Buy-Moen.
