Frost free fridges are the filthiest, unhealthiest appliances on the face of the planet, on every defrost cycle water from the melted ice flows down the drain tube into a pan or tray located near the compressor.

Heat from the compressor evaporates this water adding humidity along with any available mold spores into the house.

The drain trough under the evaporator that catches the water then feeds the drain tube are subject to mold growth, I've seen so much mold in drain tubes the water would not drain down to the pan, customer complaint water on the inside bottom of the fridge.

Back in the day when freon was not regulated the technician would use gas from the bottle to clear the line of mold. After clearing the drain tube I always pour a bit of bleach into the tube.
