The defrost drain tube on a Hotpoint refrigerator with the freezer on top keeps plugging up. The last time after cleaning and blowing the tube out, it plugged up again in approximately two weeks. The back on the refrigerator is not removable so replacing the tube is very difficult.
I have cleaned the tube with non-chlorine bleach and have blown air through it with an air compressor. The cold control is kept at three which keeps the refrigerator temp at approximately 40 degrees F.
From the odor in the living area at times, there appears to be mold somewhere in the living area but it is not visable. I was wondering if maybe mold is growing in the tube perhaps? It would be nice if there were some sort of soft flexible thing I could poke down the tube to perhaps clear out whatever is in there.
Could you give any suggestions as to how to fix this all too often recurring problem?
