OK, this isn't a "repair" question, and I guess I don't *need* to know, but this crowd is better qualified to give me a meaningful answer than the LG support gang.

Like many models, my window AC has a "dry mode", which the literature claims will dehumidify, without cooling the room.

That's perfectly clear, and a fine concept. But HOW does it do this? All dehumidifiers and ACs blow the room's air across a cool evaporator coil. A dedicated dehumidifier ALSO blows the warm air (from the condenser coil) into the room. Right?

But my window AC can't change its basic configuration, can it?

So my question: just what does the "dry mode" ACTUALLY do differently, internally? (LG will only tell me what it *promises* to do.)

Thanks!

A tiny heat strip is used to dry the chilled air just before it is exhausted into the room. The resulting drying of the air over time is their version of dry mode.
The air will be dryed anyway by the process but the gimmick of heating and drying the air gives them a reason to advertise. It works just as well without this adition but it sells don't it? Note: given the fact that they have the worst record ever of even cooling a house, let alone condition it with soft air....

I just realized that I never thanked you for your answer, Sublime One. It really had bugged me, and (yes) I am amazed by the simplicity of the feature.

And also by the ironic fact that I had thought (and LG implies) that maybe the "dry" setting saved energy, as after I don't NEED to cool if I'm using that mode. But of course I'm both cooling AND heating. What a loss.

Thanks again!

your frost free fridge does the same thing. a heated coil dries the air in the fridge and the water collects below it - so your fridge heats and cools at the same time. the only reason i could see to use this feature on your AC tho is if u just got the rugs steam cleaned....
