Here is from Dometic user manual. I have a Norcold but don't have climate control on it.

During the summer months of high temperatures and humidity,
the metal frame between the freezer and fresh food compartments may have water droplets forming. The number of water
droplets will increase if the vehicle is not air conditioned during these months. The refrigerator comes standard with a 12 V
DC climate control that will evaporate the water droplets when
they form. The climate control can be left on continuously or
used only when temperatures require it. Note that when turned
on, the climate control will draw 12 V DC power continuously.
Turn it off when a charging source is not available.
