Electrolux Refrigerator has frost or moisture buildup around the door
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.
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.
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.
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.
Refrigerator or freezer door left open
If the freezer or refrigerator door was left open for an extended period of time (e.g. more than 4 hours), frost may have accumulated on the food, evaporator coil and around the door opening. The frost should go away after the door is closed and the refrigerator goes through a defrost cycle.
