Electrolux Refrigerator has frost or moisture buildup around the door
Frost or moisture around the center mullion usually points to a mullion heater that is failing to warm the flap, so start there by testing the mullion heater for electrical continuity and replace it if it does not pass. If the heater checks out, inspect the door support and door guide next; worn or misaligned supports and guides prevent the mullion flap from sealing tightly and let humid air condense and freeze. After that check the door gasket for twists, tears, or gaps, since a bad gasket will also let warm air in and cause frost buildup. Finally, rule out a simple user issue like a freezer or refrigerator door being left open for hours, which can create temporary frost that clears after a defrost cycle. If you need parts, enter your model number on RepairClinic.com to see the exact mullion heater, door support, door guide, gasket, or other replacement that fits your refrigerator, along with repair help and testing tips if you are unsure which component has failed.
01 - Electrolux 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.

Common
02 - Electrolux 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 - Electrolux 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 - Electrolux 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.
