Do I need to keep it off until it thaws?
YES!
Keep it OFF till it thaws out!

Happens to our FD Office AC rather often.

Cause:
Room HOT and HIGH Humidity ...
then the AC turned on to too LOW a desired temp.

Prevention:
Cycle the AC ON more often to keep the room less hot AND
allow the AC to remove some of the high humidity;
AND turn the desired temp UP until the AC has a chance
to SLOWLY lower the Temp & Humidity.
