This invention relates to an improvement in the operation of a domestic refrigerator. The improvement comprises the addition of a mullion heater to heat an exterior surface by the passage of warm refrigerant through a tube mounted on the interior surface opposing the exterior surface. The tube is embedded in a malleable mastic substance of substantial thermal mass which is capable of maintaining the temperature of the exterior surface above the dew point of the surrounding air during periods when no warm refrigerant is passing through the tube.
