The oak is working really well, very little heat at all.
You mean very little heat on the inside, right? The outside should definitely be warm during operation.

What I'm getting at is this; Unless the cabinet is doing a really good job of casting off it's heat, the refer unit is expending a lot of it's capacity recycling it's own heat. Since wood is a very good insulator, I was concerned that the (beautiful) oak cabinet may be reducing your refer's efficiency quite a bit. That's one reason why deep freezers use a thin metal exterior shell. The condenser (hot) lines are just behind that shell and the exterior walls act as a heat sink. Here's a pair of pics to illustrate.
