What is oil-like substance dripping from KitchenAir Superba ice maker on side-by-side refrigerator?

Make sure your manual doesn't say something about inline filters, or a float that might be sticking in off position. Depending on how ice is made sometimes they have a float to where water rises so hight then gets shut off to freeze and form the ice.

SOURCE: drain pan leaking?

there is a drip pan located underneath you ref but most likely your prob is a plugged drain line coming from the freezer. when you ref goes into automatic def the water doesnt run out into the drip pan but instead onto your floor..

you can clean the drain line by removing the rear cover in the freezer compartment and using hot water to thaw the drain below the evap coil.

SOURCE: ice maker not filling with water

I have a model KSRG25F and found that the solenoid that controls the water to the icemaker was not working. I tested by switching the water dispenser connection to the ice maker coil.
And then had the wife push the water fill in front of the fridge. I had aready changed out the control board in front because I didnt have the flash codes or solid led when simulating door closed. the parts is about $55 and hope that does it. Good Luck

Found someone that was not going to charge me money for advice.

had the same problem. Turned out it was a worn out valve that controls water distribution. Remove the back panel. There is a (in my case) blue part with one water line coming in and two water lines coming out. This houses an electromagnetic control which directs water either to the dispenser, or the ice maker. I took it apart a few times, and didn't see anything wrong, but ordered a replacement, easily switched it out and viola! No more leak. Ordered the part online for less than a repair visit.
