nestork, trader4,

Thank you for your responses and the valuable information. It is quite helpful.

I'm glad that you said it wasn't necessary to take a photo. I literally haven't had a chance to sit down and type since the alarm clock went off. So I haven't hauled out the fridge and removed the back panel to take a picture. Unfortunately, that also means I haven't been able to check for a removable panel in the freezer to see if there is uniform frosting. However, it is a valuable nugget of info -- a checklist item. The next few days will be at the same pace as today, but I'll take a shot at first opportunity, as well as trying the towel method of checking for oil.

I appreciate the clarification about the nature of the coils. I actually surfed for fridge designs about 24 hours ago, and got the big picture, cartoonish though it may be.
