Estate Refrigerator has frost or moisture buildup around the door
Frost or persistent moisture around the door usually points to a mullion heater that no longer warms the flap, so start there: test the mullion heater for electrical continuity with a multimeter and replace it if it has no continuity. If the heater checks out, inspect the door support and door guide for damage or misalignment that keeps the mullion flap from sealing tightly. Worn, twisted, or torn door gaskets are another common cause because gaps let warm, humid air in and let frost form around the doors. Sometimes the simplest cause is a door left open for hours, which will usually clear after the next defrost cycle. These checks cover the most likely fixes when you see frost or moisture buildup around the door and can save an unnecessary service call. If you need parts, enter your refrigerator model number at RepairClinic.com to see the exact replacement mullion heater, door support, door guide, or gasket that fits your unit.
01 - Estate Refrigerator Mullion Heater
A defective mullion heater flap may not be able to heat up periodically to melt any frost or moisture that forms on the flap due to increases in room humidity. You can use a multimeter to test the mullion heater for electrical continuity to determine if the component is working. If the mullion heater has no electrical continuity you should replace it with a new one.

02 - Estate Refrigerator Door Support
If the mullion heater flap has frost or moisture buildup, it's possible the door suport is damaged or misaligned and not allowing the flap to form a tight seal between the refrigerator doors. Inspect the door support for wear or damage and replace if necessary.
Common
03 - Estate Refrigerator Door Guide
If the mullion heater flap has frost or moisture buildup, it's possible the door guide is damaged or misaligned and not allowing the flap to form a tight seal between the refrigerator doors. Inspect the door guide for wear or damage and replace if necessary.
Common
04 - Estate Refrigerator Door Gasket
A door gasket should form an airtight seal around the appliance's frame to keep the cold air in and the warm air out. If the door gasket is twisted or torn, gaps can form that will allow warm air in, resulting in the freezer not freezing properly. Inspect the door gasket for any damage and replace with a new one if necessary.
Common
05 - Refrigerator or freezer door left open
If the freezer or refrigerator door was left open for an extended period of time (more than 4 hours), frost may have accumulated on the food and around the door opening. The frost should go away after the door is closed and the refrigerator goes through a defrost cycle.
