Admiral Refrigerator has frost or moisture buildup around the door
If you have frost or moisture building up around the door mullion or between refrigerator doors, start by checking the mullion heater flap — it should heat periodically to melt condensation, and a failed mullion heater is the most common cause. Next inspect the door support and door guide for damage or misalignment that keeps the mullion from sealing; a bent guide or worn support often results in a fridge door not sealing or a refrigerator door not closing properly. Also check the door gasket for tears or twists that let warm, humid air in and create frost. Less commonly, the issue is simply that a door or freezer compartment was left open for hours; that frost usually clears after a complete defrost cycle if there is no failed component. You can use a multimeter to test the mullion heater for continuity, and on RepairClinic.com enter your model number to find the exact replacement mullion heater, door support, door guide, or gasket parts for your refrigerator.
01 - Admiral 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 - Admiral 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 - Admiral 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 - Admiral 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.
