RE: Wet Box
Moisture on the outside of a refrigerator indicates the insulation is poor. Moisture inside a refrigerator indicates moist air is infiltrating into the box. Any time an object is ten degrees colder than the air, moisture will collect on the object. Moisture always collects on the refrigerant evaporator and forms frost in a refrigerator. When the thermostat is set for a high temperature cooler instead of a lower temperature refrigeration, frost will not build up on the evaporator, instead it will melt and keep the refrigerator wet inside. Refrigerators are dry inside, not wet, until defrosted. Even self-defrosting refrigerators are dry inside because they capture the moisture and drain it away. Once I found moisture leaking into a refrigerator on a 41 Morgan OI when it rained. Moisture is also removed from the products placed in the box but it again shows up as frost on the evaporator and not as a wet liquid. If moisture in its liquid form is not leaking into the box then the door or lid seal must be leaking air into the box. To test the firmness of a seal’s contact, the door can be closed on a narrow ribbon. If there is no resistance when the ribbon is pulled out, that area of the seal is leaking.
