MacBook Air Charger Turns burning hot

Please refer to this excerpt from If your USB-C power adapter isn't charging your Mac notebook:

If the adapter gets warm

The USB-C power adapter can become warm during normal use, so be sure to use it in a well ventilated area. Always plug the power adapter directly into a power outlet using the AC plug, or place it on a table or other well ventilated area when using the Power Adapter Extension Cable (sold separately).

Avoid placing your adapter in a poorly ventilated area, like on a couch, thick carpeting, bedding, or a pillow. Avoid covering the adapter with a blanket or other insulation.

The power adapter might turn itself off if it gets too warm. If this happens, disconnect the USB-C cable from your Mac notebook, then let the power adapter cool down before handling it.

If necessary, get your cable and power supply evaluated.

If you are using the older MagSafe power adapter, refer to Using and maintaining your Apple MagSafe Adapter.

To identify the power adapter you're using, refer to Find the right power adapter and cable for your Mac notebook.

For general operational information read Using Apple power adapters, cables, and duckheads with Apple products.

Do not use that charger. Use another one and see whether that operates normally.
