The 661 is a built-in side-by-side refrigerator/freezer from the 600 Series with front venting, adjustable wire shelves, and adjustable door shelves. It’s no longer produced.
A unit that runs constantly without ever settling into a normal on-off cycle is the issue we hear about most on a 661, which points to the compressor struggling to reach its set point rather than simply working hard. A cabinet that recovers slowly after the door’s been held open, and one side running warm while the other holds temperature, are the other common calls on this model.
