I am actually unable even to figure out how to get to a screen that would show me an error code, it only currently says "system malfunction".

There you go. Your outdoor sensor is giving you the trouble code.

Is there anything I can do now so that I can get my ac working again? It is REALLY hot here!!!

Accepted Answer

The following is from your manual.

The user can press the right side button to dismiss the notice. The
regular run mode screen will then appear except “SYSTEM
MALFUNCTION” will appear in place of the day/time. If the error
has not disappeared within 24 hours, the above display will return.
If the error code disappears, “SYSTEM MALFUNCTION” will
disappear and the day/time will reappear.
