Anti-sweat Cabinet Heater
These were necessary to prevent condensation on the outer edges of the cabinet during humid weather, unfortunately if the freezer is not staying around 0F these heaters will get too hot and do them selves in.
You can use the ref without this heater [ and you will even save a few dollars a month ] but the cabinet will likley sweat badly in the summer and rust, mold and leak on the floor as a result.
PS, The door gaskets were sticking to the cabinet because the ref was just repainted, not because of the cabinet heaters, this often happens when refs are repainted, often the paint used is not comparable with the vinyl door gasket material.
