Answers:    thieve out the bottom vegetable bins and see if there is a stopped up river drain, a lot of gunk can collect lower than the bins. with or in need a drain. another place water drains to is bringing up the rear the fridge down the bottom where the compressor is. there's a container there that collects the marine from the defrost cycle that the fridge does every day. the warmness from the compressor is supposed to then evaporate that wet. sometimes over time however it collects and gets calibre.
unplug the fridge to move it out. be aware of any water lines you might own to the ice inventor. the air from the freezer comes down to cool the fridge. check the freezer for the odor also.
appropriate luck to ya.
