Amana Refrigerator has frost or moisture buildup around the door
Frost or moisture on the mullion flap between your Amana refrigerator doors usually means the mullion heater is failing to heat and melt condensation; use a multimeter to check for continuity and replace the heater if it’s open. If the heater is fine, inspect the door support and door guide next—damage or misalignment can keep the flap from forming a tight seal and let humid air condense. Also check the door gasket for twists, tears, or gaps that cause the fridge door not sealing and allow warm air in, which can leave frost around the opening or prevent the freezer from freezing properly. Finally, confirm the door wasn’t left open for an extended period, since that often creates temporary frost that clears after a defrost cycle. Enter your model number on RepairClinic.com to find the exact replacement mullion heater, door support, door guide, or gasket for your refrigerator so you can fix the seal and stop the frost.
01 - Amana 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 - Amana 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 - Amana 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 - Amana 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.
