This replacement part is a door and is intended for use in refrigerators. This door is able to seal the appliance shut while not in use, allowing the food to stay cold.A new door might be needed if the current one is no longer able to seal properly. This can be due to normal wear and tear in the door sealant or the door itself. If the temperature inside the appliance is higher than normal, the door may not be working as needed and should be replaced if this is the case. This should be a fairly simple repair.This is a genuine OEM replacement part made by GE. This part is sold individually and is sourced directly from the manufacturer for long-lasting use.
