AC Unit problems Model NCA-08C/X1E

Problems:

I have used this unit a handful of times.

Today 6-14-2024 seems like total failure. Nothing seems to be working.

High Fan sounds low most of the time.
When it does go to high it sounds like it.

Can’t put it into Fan mode at all.

I have unplugged it because Plugged in, it makes a low rumble sound with no power on.

While in the On or off mode it makes popping sounds.

After plugging it in the other day after work the E2 Temp Senor Failure Code popped up?

Dehumidifier Mode set at 75 Degrees. The temp on my device’s temps went to 65 in here.

E4 just popped up for the first time?

Shutdown and does not come back on. If it does come back on it is hot in here again. But it seems to turn off again after a few minutes? The last couple of uses it never cools down in here?
