SOURCE: need to fix a broken moen kitchen faucet

I had the same problem with my Aberdeen single lever with a pull-out sprayer a few months back. If you are the original owner of the faucet, it's under warranty; you shouldn't have to pay for any parts. Call: 1-800-BUY-MOEN (1-800-289-6636) and tell Customer Service what the problem is. They will send you the Handle Mechanism Kit at no charge. (Mine was part #93980 for my Aberdeen faucet, but yours may be a different part number.) It's tricky to take apart and get back together but my husband and I have zero plumbing experience and got it all fixed in about 20 minutes. The Moen.com website also has exploded parts diagrams of all their faucets so you can identify exactly what part you need, and they have some little videos and slideshows to show how to replace parts. If you can't reach Customer Service on the phone, you can go to "Contact Us" on their website and email them a description of your problem.

Turn off water

Remove the handle with an allen wrench, usually 1/8".

Unscrew the dome with a pair of channel lock pliers with a rag to prevent scratching.

Wiggle out the old cartridge with the channel lock pliers.

Clean all innards with WD-40.
