Our Kitchenaid kscs25fvms01 will click and you can hear the compressor and fan turn off, and then a second later it'll click again and it'll turn back on. I've cleaned a small amount of dust out underneath the unit, but not enough that I would think it would affect it. Other than the clicking, it seems cooling and freezing doesn't seem to be affected, but the ice maker is leaking a small amount of water into the freezer.

Any ideas of what part to check first?
