This morning when I turned on the hot water at my kitchen faucet (Moen cartridge faucet) nothing happened, no water. The water only works on cold. PLEASE HELP!

Do you have hot water in other faucets in your house ?

Please respond to Milo's question.
Also if you tell us the model number of your faucet, Thanks.

You need to pull the cartridge out of the faucet and replace it , with a new one, sometimes they do not come out well, they sell a moen cartridge puller, that makes the task a little easier.. good luck
