It possibly was "iced up", or frozen.

"Run the Heat ??
Is this a combination HEATER AND Air Conditioner unit?
I meant to run the unit with the temperature control set "warmER than Max COOLING" ...
still in the air condition setting range, but warmER than "Frigid/Super Cold".

"but we're going to try to continue to turn it off at night to let it thaw out some."

MOST Air Conditioners are a lot happier running on "Full Automatic" and a "reasonably cool"
temperature setting; allowing the AC to determine when to run and when to rest.
Running at a constant temperature setting that the unit can achieve and maintain,
the AC can keep the humidity under control without risking a freeze-up.

The AC should automatically run less during the cooler nights; but it still needs to run for
part of the night to keep the humidity under control.

Learn WHERE to look to see the condenser coils.
