Some RV fridges have a switch of some sort that turns the light on all the time, using it as a little heater (for climate control or cold weather operation or some such, I can't recall precisely what at the moment).

Never heard of anything like this nor would it make any sense at all.

Called a Low Ambient Temperature switch or control (LAC or LAT). Used on some Dometic models. In low temperatures, the fresh food compartment stays at temp, but the cooling unit doesn't run enough to keep the freezer below zero, so they add heat to the fresh compartment, making the cooling unit run enough to keep the freezer cold.

On my fridge this switch is located in the freezer compartment door jam way up top - almost impossible to locate unless your looking for it. Open the door and look for black sitch on black trim.

Yup, it actually exists even though they didn’t bother letting Sound(of his own voice)Guy know about it. It’s a switch I’ve forgotten about several times myself, and have to reacquaint myself with once in a while. It works exactly as described, when it’s “on”, the little light stays on when the door is closed.
It’s the same method I use for my beer fridge in the garage during the winter. The freezer section doesn’t stay cold enough when the ambient temps are below 40-ish, so I put a jumper across the door switch to make the light stay on all the time. The 25w bulb adds just enough heat so that it runs a little more and the freezer stays at the proper temp. Amazing.

Great info but sorry, absolutely
no switch anywhere on my particular DM2652 ... I've been over it with a fine tooth comb and I can guarantee there is
no switch anywhere. :( However, according to
Chris's explanation perhaps the light in the OP's fridge is intended to
not go off. :h
