I can't afford a pricey visit for repairman. I have water pooling on top shelf of the refirgerator. It is frost-free. No ice maker installed. Freezer on top. I defrosted it and thought that may solve the problem. I put things back in my refrigerator, as it seemed okay. It started pulling water again.

I would like to attempt to fix this myself, if it is not too complicated. I thought that by defrosting it would have thawed any tubes/pipes frozen.

Thanks in advance for any replies.
