The partial meltdown at Three Mile Island in 1979 was primarily caused by a stuck-open relief valve that led to a loss of coolant and overheating of the reactor core. This caused significant damage to the fuel rods and led to the release of radioactive gases into the environment. Ultimately, the failure of the relief valve, combined with operator errors and design flaws, contributed to the accident.

Why did chernobyl blow up but three mile island didn't?

The reason Chernobyl failed is because the plans used to design the plant were old and out of date. The technology was years behind. Where as Three Mile Island has multiple fail safes. All nuclear reactors have these. If something fails they have a fail safe to stop it, and if that fails there is another; and so on and so on. Three Mile has 4 fail safes, two of which failed and the third caught it preventing disaster.
