I have a kitchen faucet that has flow from the hot water line (confirmed by shutting the cold water valve) but it is not hot. Rest of the faucets in the house run hot water just fine. Please let me know your thoughts.
 
How old is your kitchen faucet? Try disconnecting the hot side under the sink and run the line into a bucket to see
if the water is hot. If its a single handle faucet it could be a cartridge..
 
Very vague description, take a big breath and start over.
More details.

What cold water valve was shut?

Meanwhile, there could be a cold to hot crossover connection elsewhere in the house, or even right in that kitchen faucet valve cartridge.

Post some pics of what you are looking at.
 
Thanks all.

I'm attaching a pic now. If you need me to focus on any aspects of the set-up, please let me know. I really appreciate the guidance.

Now that it's mentioned, I think the faucet cartridge is what's probably the issue. Faucet (single handle) is old needs replacing (cheap partly plastic model that is cracking, etc.). So, I am planning to replace either way. Maybe that resolves the issue once I hook up the new one.

Turning to the pic, the top two valves have flexible pipes traveling up to the faucet. One has some red on it apparently indicating hot, and the other blue. I was wrong above. I turned off the red and the faucet worked when on and all the way to one side but did not when all the way to the other side. Tried to alternate to shut-off the blue, but I have a faulty valve there (water starts fizzing out as I close it, but is fine when open). In any event, not sure if any of this helps in sorting out what's going on.

For your info, lower left valve connects to a dishwasher; lower right valve connects to a hot water dispenser.

Happy to supply other information, but I'm thinking the new faucet will solve the issue.

Update: I installed the new faucet. I have hot water, but only sometimes and only after a long wait. It's odd. The hot water seems to be fighting to come through, but does not always make it. Rest of faucets/shower heads are fine when it comes to hot water in the house. As before, any thoughts would be appreciated.
 
Leave that faucet running on hot
One at a time go to the other faucets(one at a time) shut hot and cold off under tbe sink then go to your kitchen faucet untill you have done that to all faucets maybe like others said there maybe another cross over ii had something like this happen at work and it was a single handle faucet i removed it and installed a better 2 handle faucet
