Hot water not working in kitchen faucet. All other water working fine

Hi luveegee and welcome, you'll get a better answer posting this in plumbing. Also post what type faucet and whether it is single handle or not, also have you had any plumbing work done recently?

If it is a single handle faucet and all other faucets have hot water, you could have 2 possible issues, plugged angle stop or plugged inlet port to the cartridge. My guess would be the cartridge. Make sure water is getting to the faucet by checking flow from the stop to the faucet. If that is open, the cartridge is most likely plugged. You will need to disassemble the faucet and clean out the cartridge.
