Haven't used the kitchen faucet sprayer for a while . Today I used it and its stuck.
Water only comes out of the sprayer but not the main faucet.

Time for a new sprayer. Easy fix. Go to home Depot or Lowe's and buy just the sprayer and change it out. My sprayer handle broke and just replacing the entire sprayer (not the hose) fixed mine. Yours should cost less than $10 to replace/fix.
