After our piece-of junk US made Amana fridge, sold by Kleenmaid, at our previous home needed repairs, I bought the parts online from the US including a couple of coil cleaning brushes.
The coils were incredibly dirty.
Next time it broke down, we bought an LG which we sold with the house, and bought a second one for our current home.
It does not appear to have any accessible coils and I suspect that they are under the bulge on top of the fridge.
