Another problem that happens with the suction line is that the capillary tube can separate from the suction line. This will cause long running times of the compressor, a decrease in the cooling temperatures in the refrigerator, frosting and or sweating of the suction line and the resulting water running in the floor under the refrigerator. Torn door gaskets and warped doors can be a source of leaks. The hot humid air enters the refrigerator, reacts with the cold air in the refrigerator, condenses and runs water out the open door and also condenses on the metal where the gasket should seal and drips into the floor. This leak is usually found in front of the refrigerator.
Moisture forms on the mullion between the freezer and fresh food section and drips in the floor.
This is generally caused by defective electric heaters inbedded under the mullion to keep the refrigerator from sweating in a humid area, or the moisture control switch being turned off. A different type drain. The newest production models now have a drain hose, but from 1989-1997 they didn't. Some customers say they don't have a turkey baster to clean drains. I have suggested they try their vacuum cleaner, reverse the vacuum hose to where it is blowing instead of sucking.
