Water pools under the crisper drawers and looks as if it is draining from the upper freezer down the side of the refrig door, looks like the little hole under the crisper is clogged with rust?? It is a old whirlpool top freezer/ frig

Mine clogs with a soft fungus mat but rust actually sounds better. I run a stiff wire like an unwound hanger into the hole and open it up so the water will drain onto the tray made to collect this water underneath the fridge. Last time I left the wire in place with a long handle and I haven't had water to mess with for many months now. My hole is between the two crisper drawers and when I get into either of them the wire gets a jiggle and I guess that's all it takes to keep the hole clear so the water can drain like it's supposed to.

Otherwise the fungus builds and builds until it sluffs off as a wad and plugs up the works on a regular basis. Too funky for sure.
