re: Interior of cabinets sweating.

How cold is inside your house, I.e., what is the air temperature inside the cabinets where it’s sweating? Sweating (condensation) would/could occur if the temperature of the cabinets is colder than the dew point temperature of outside air potentially infiltrating around/inside those cabinets from the exterior wall or attic. That’s the “why”.

I’m looking at outdoor temperature/humidity/dew point sensor underneath my porch (Baton Rouge) as I type this and the dew point temperature of the outside air is 77 F right now.

You need to check for outside air infiltration around those cabinets.
