I need help on food disposer

The motor is stuck. Use the allen wrench that came with unit and insert into spot under neath the unit and see if you can unstick it.

If not successful unit needs to be replaced since it is frozen solid and will not turn nor grind.

It will work but it sounds like metal is grinding in it.

Use vacuum cleaner to see if something is loose.
Otherwise, a noisy disposal that works is functional and not dangerous... but annoying.
Life of disposal is probably shortened since the bearing seal could have failed letting water in, and bearings could be rusted.
Replace disposal if noise bother you.

Loud roaring, grinding noise that appears to be coming from the motor - the food trap appears clear

I would unplug it or flip the breaker to it and stick the shop-vac down in there (or your hand). 99% of the time it's some type of debris.
