What's this socket/plug at the bottom of my fridge? (pic)

I just scored a free refrigerator from a friend to use as my ferm chamber, and in cleaning it, I noticed this socket/plug loose at the bottom. This is looking straight at the fridge, and is above the wheel on the lower left side (it's a side-by-side fridge/freezer, so technically, this is below the freezer section).

It was concealed by the plastic grill most fridges have at the bottom. Friend has no clue and said the fridge worked fine. You can't quite tell from the angle of my photo, but there's about 4-5 inches of cord behind the plug going under the fridge and into the guts.

Any thoughts?

i'd venture a guess to be a socket for a ice maker unit in the freezer.

I don't see anything for it to plug in to. If I did, I'd probably attach it and never think about it again. This is just hanging loose without any obvious attachment point.

it could plug into the bottom of the door? Does the door have water through the door, or any electronics in it? I have seen that at the top, and the bottoms.

Could also be for a "testing read-out"

Esmitee, you have it! Powers the door electronics.

I dug around the underside of the freezer door and found the other connector. It had gotten twisted around the water tube and wasn't readily apparent. Thanks!

[Edit] and I just realized this is probably what refluxologist was probably trying to tell me too. Thanks again!

Cool, it had to be for something!
