Started removing everything from refrigerator and taking out every part and piece I could...then got to the cover over some coils with fins on them and noticed that they have front and condensation on them and therefore there was a drip pan under it...I could see pan was rusted but it wasn't until I figured out how to remove it that I could see it was rusted through allowing collected condensation to drip through and into bottom of refrigerator instead of run out out the spout and into the drain tube. Ordered the new drain pan from Appliance pros, received in two days later and installed...problem fixed! Oh yeah, also thoroughly cleaned the refrigerator while apart making it look good as new when done!
