Hi

My LG Fridge, model GR-721-RW, which has the freezer on top and no icemaker, is dripping water from the freezer compartment which is ending up on the floor.

I have removed the back panel. The drip tray is dry and the tube leading to it is clear. The controls in the freezer compartment appear to be clear (ie. Everything moves properly). Where might my drain be blocked and how do I get in to clear it? I couldn't see any point at which I could get at anything.

Thanks
