A refrigerator door that will not close tightly can let cold air escape and lead to spoiled food. One common cause is a worn lower door hinge. This part helps keep the door aligned and allows it to close smoothly every time.
The lower fridge door hinge (part number AEH36821908) is located at the bottom of the left fresh-food door. It is spring-loaded to help the door open and close properly. Over time, it can wear out or break, which can cause the door to stop sealing as it should.
How to Identify a Worn Lower Door Hinge
Knowing when the hinge needs replacement can help you avoid larger issues with your fridge. Look for these signs:
- The door sags or appears misaligned when closed.
- There is a noticeable gap between the door and the fridge frame.
- The door requires extra force to close completely.
- The door swings open unexpectedly when left partially shut.
- Cold air escapes, making the fridge work harder and increasing energy use.
- Visible wear, rust, or bending on the hinge mechanism.
What You’ll Need

- Flat-blade screwdriver
