I have a Mitsubishi Electric “MSZ-GL06NA” and live in NYC.
Why does the heat pump never stop when set to the dehumidify mode?
The apartment just keeps getting colder and colder but never any drier(?).
When will it ever stop or Does it need servicing?
Technology Connections recently posted a detailed video about dehumidifiers that’s worth watching. But a key takeaway is that on an AC, the hot side is outside (making the inside cool), while in a dehumidifier they are directly next to each other (condensing the moisture).
Without looking into the specifics, my guess is that it’s not routing the cold air over the hot side to keep things inside the same temperature.
