Magic Chef Refrigerator has frost or moisture buildup around the door
If you’re seeing frost or moisture buildup around the refrigerator door, the most likely culprit is a failed mullion heater that isn’t heating the center flap to melt condensation and frost. Start by testing the mullion heater for electrical continuity with a multimeter and replace it if it’s open. If the heater checks out, inspect the door support and door guide next; bent or misaligned supports and guides prevent the mullion flap from forming a tight seal between doors. After that check the door gasket for twists, gaps, or tears that let warm, humid air in and cause frost, and confirm the freezer or refrigerator door hasn’t been left ajar for hours. These problems can look like the appliance is not defrosting or like the refrigerator door not closing properly, so pay attention to seals and alignment when diagnosing. For parts, enter your model number on RepairClinic.com to see the exact replacement mullion heater, door support, door guide, or gasket that fits your refrigerator and get back to a tight, frost-free seal.
01 - Magic Chef 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 - Magic Chef 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 - Magic Chef 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 - Magic Chef 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.
