What kind of valves do you have under the cabinet? 1/4 turn like I have that might get bumped?

Let's start checking. Shut the water off under the cabinet and open up the valve and remove the cartridge. Now place a pan over the opened faucet and turned the hot water back on under the cabinet. Do you get a strong stream? If so then the hot water inlet on the cartridge is clogged. Checked and cleaned the inlet port. Good luck, Tom

When you had not hot water at the kitchen sink, did you have hot water at other places, like the bathroom sink?
