Refrigerator door not opening/closing properly

French door refrigerators will often use a mullion heater flap which flips open as the two main doors are closed to provide a proper seal. If the mullion heater is misaligned or damaged, it can prevent the doors from closing properly. Inspect the mullion heater for any damage and replace it with a new one if necessary.

Refrigerator has frost or ice buildup

Refrigerator has frost or moisture buildup around the door 

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.
