A:Answer I agree with Edward.
The neverclean is a marketing ploy to the lazy from GE, it is also an excuse to engineer a fridge even tighter than before. The condensor coils likely can't be cleaned directly, they are housed in a wire cage if you will, and the cage collects the dust before it gets to the condensor, so will the condensor may not have dust on it itself, the air will get restricted through the wire cage dust build up.
Pull the fridge out and remove the cover on the lower back of the fridge. There will be a round wire cage looking thing with dust all over it. I would unplug the fridge. Use a vacuum with a brush attachment, make an old toothbrush, or coil brush, whatever you have to loosen the dust and suck it away with the vac. If you have a coil brush you might can bend it so it reaches the back side of the round cage. If not, maybe run your hand across the back while providing air movement with the vac so the dust gets sucked away.
Great job on wanting to maintain you equipment. Shame on GE for such a hard design to clean and maintain for those of us who don't stare at our phones and TV's all week.
