Why is my hot water not working in the kitchen

If you have hot water in every fixture but the kitchen sink I'd suspect the hot water faucet cartridge or valve. Shut off the main and disassemble the faucet handle and the cartridge or valve. Clean it out, flush it or even buy new. This should fix your problem.

reyrey,
I know there are times when I can read minds, but this question needs some idea of what you have. Does water still come out of the hot faucet? Were there any appliance or fixture changes? Does the same problem occur in the bath room? Is there low water pressure from the cold faucet?

A little help please... nm
