I have a new GFCI outlet with the LED light not on. But the outlet has power and the load outlet also has power. The test button works and you can reset the GFCI, but no LED light comes on. What can be wrong?

(I believe) It depends when your GFCI socket was manufactured & (perhaps) who manufactured it. I have GFCIs without any LEDS and some with LEDs (& GFCIs with different color LEDs for different feedback status). The ones with LEDS behave differently. On one the LED is green when the GFCI is good & power is available for connected outlets. Another has an amber LED that comes on when the unit has tripped (or the TEST button has been pressed). Perhaps GFCI electrical device standards in 2024 have now been harmonized so the LED colors & functions now all behave consistently. (Or perhaps they haven't !). I've learned the hard way to always use a plug-in-socket-tester when I have an issue and not to assume I know what each GFCI LED is telling me.
The light should only come on when the GFCI is tripped in most outlets. There are GFCI outlet testers available; big box home stores carry them. If the light doesn't come on when the outlet is tripped and the outlet tests correctly, it's probably the outlet. Replacing the outlet would be the way forward to fix that. The GFCI tester may show other problems which could cause unexpected behavior and should be fixed.

1All of my GFCI outlets have an LED on to indicate they are working. I would assume in this case the outlet is wired wrong, either swapped line and load or swapped hot and nuetral Commented Feb 1, 2018 at 6:21

2Some GFCIs light up to indicate good, some light up when tripped. Yes, the inconsistency is annoying.– keshlamCommented May 20 at 14:12
