Target sells a coil cleaning brush. I might buy one this weekend. My Maytag has a cover in the front that comes off and you can get into the coils. there. I can't get to all of them but can get to most of themI hope yours is designed better than mine. No way it is possible to clean the "coils" under the refrigerator, they loop back and forth with the open area on the sides - right where the "cabinet" sides are. There is no way to get any sort of vacuum attachement past the loops in the front.
