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.

Refrigerator Isn’t Defrosting — Refrigerator Troubleshooting

This free troubleshooting video shows quick maintenance tips including cleaning the door gaskets, cleaning the condenser coils, and using a deodorizer for keeping your refrigerator working safely and efficiently. Manual-defrost refrigerator/freezers: Manual defrost refrigerator/freezers require very little maintenance. When frost has accumulated on the inside walls of the freezer to a thickness of ½ inch or so, remove the food from the refrigerator/freezer, turn off the thermostat or unplug the unit, and allow all of the frost to melt. Once the frost has melted completely, turn the unit back on, wait for it to reach its operating temperature, and restock it with food. Self-defrosting refrigerator/freezers You don't need to manually defrost your self-defrosting refrigerator/freezer. Every 6 to 8 hours, it heats up its cooling coils slightly and melts any frost accumulation on the coils. The resulting water drains into a shallow pan at the bottom of the refrigerator/freezer. There's no need to empty the pan. The water in it will evaporate. But it may begin to smell bad over time. You may be able to remove it for periodic cleaning by detaching the lower grill and sliding the pan out the front of the refrigerator/freezer. Note... When mold grows in the drain pan, it is sometimes considered to be a health concern. If your drain pan is removable, and if you're sensitive to mold, consider cleaning the drain pan periodically. Under your refrigerator/freezer is a set of coils and a cooling fan that you need to clean at least once a year. The coils may look like a grate or like a wide radiator. Unplug the refrigerator/freezer and use a Refrigerator Condenser Brush (available in the parts section of our website), and your vacuum cleaner to clean any lint, pet hair, and so on from the coils. If the gasket or interior of the refrigerator/freezer needs cleaning, try Refrigerator Cleaner to clean the surfaces. You can find this useful product in our parts section. If you're unable to find the information you need on our website, we suggest that you use a search online to find a reliable online repair forum. It's likely that your question has already been answered there. We also recommend contacting your product's manufacturer or calling a local repair technician.
