There is a plug, and it's buried behind the fridge. I ended up taking our fridge out too because we don't use it. It was a while ago, but if I remember correctly, there are two screws in the front that are a pain in the neck to get to, and there is also one on the side that's tough to get at. All of the screws were very tight, and had started to strip, but I was able to eventually work them free. If they are too badly stripped, a possible option is a long blade on a sawzall - there should be enough clearance below the fridge to get the blade in there and you should be able to hold the saw off the front of the fridge.
