Moisture causes
If factory installed, you have an Adler Barbour SuperCold unit with a stainless steel PowerPlate. Excessive moisture is normally a result of a leaking gasket on the door(s). The water in the air leaking into the box condenses on the cold surfaces. It also helps if you plug the drain. To test the gaskets, take a dollar bill, and in several places around the door, close it on the bill. If the bill is easily pulled out, replace or repair the gasket. If you find the gaskets are sealing well, it's possible the system is slightly undercharged, and needs to be topped off with refrigerant. If that's the case, give us a call, we can reccomend a service dealer in your area.Regards,Gary ButtreyWAECO Adler Barbour860-664-4911
