How to Replace WR2X8345 Door Shelf Retainer Bar End Cap on GE Refrigerator — Step-by-Step

You reach for the milk and the entire door shelf dumps its contents onto your kitchen floor. The culprit? A cracked or missing end cap that's supposed to hold the retainer bar in place. I've seen this exact failure on dozens of GE and Hotpoint refrigerators, especially on models like the GTS18HCRERWW and TBX18TAZERWH where these little plastic caps take constant abuse from heavy gallon jugs.

The WR2X8345 end cap might look insignificant, but it's the anchor point that keeps your door shelves stable. When it cracks, the retainer bar slides out and everything goes sideways—literally. Here's how to fix it without calling a tech.

What You Need Before Starting

• Replacement WR2X8345 end cap
• Flathead screwdriver (optional, for stubborn pieces)
• Clean cloth

Repair Time: 5-10 minutes
Difficulty: Easy — No tools required for most installations

Safety First

You don't need to unplug the refrigerator for this repair. However, remove all items from the affected door shelf before starting—you don't want anything falling while you're working. If you're replacing multiple end caps, work on one shelf at a time to avoid mixing up parts.

Step 1: Remove the Existing End Cap

Open the refrigerator door fully for easy access. Locate the damaged end cap on either side of the door shelf retainer bar. If it's cracked but still attached, grip it firmly and pull straight out from the door liner. The cap slides into a slot molded into the door—it's not screwed in. If pieces broke off inside the slot, use a flathead screwdriver to carefully pry them out without scratching the door liner.

Step 2: Clean the Mounting Area

Wipe out the slot where the end cap sits with a clean cloth. You'll often find sticky residue from spills or small food particles that got wedged in there. A clean surface ensures the new cap seats properly and grips securely. Check that the retainer bar itself isn't bent—if it is, you might need part WR02X10518 for the full bar assembly.

Step 3: Install the New WR2X8345 End Cap

Take your new end cap and examine how it's shaped—you'll notice one end is slightly wider and has a tab or ridge. This wider end faces toward the inside of the door. Line up the cap with the slot and press firmly until you hear or feel it snap into place. It should sit flush with the door liner. Don't force it at an angle or you might crack the new cap before you even use it.

Step 4: Reinstall the Retainer Bar (If Removed)

If you removed the entire retainer bar to access the end cap, slide it back through the slots on the door shelf. The bar should pass through both end caps and hold the shelf securely against the door. Press down on the shelf to make sure it's locked in position. The bar prevents the shelf from tipping forward when loaded with heavy items.

Step 5: Load Test the Repair

Place a gallon jug or other heavy item on the repaired shelf. Open and close the door a few times, checking that the shelf stays level and doesn't rattle. The end cap should keep the retainer bar from sliding out of position. If the shelf still feels loose, remove it and verify both end caps clicked fully into their slots.

Testing After Installation

Load your door shelf gradually, starting with lighter items. After 24 hours of normal use, inspect the end caps to make sure they haven't worked loose. On models like the CTX16EYXKRAD or TBX21IABLRWW, these caps handle a lot of weight, so check them periodically—especially if you regularly store heavy bottles on that shelf.

Frequently Asked Questions

Will this end cap fit both sides of the door shelf?

Yes, the WR2X8345 is universal for left and right sides on compatible GE and Hotpoint models. The cap design is symmetrical, so you can use it on either end of the retainer bar. If both caps are damaged, order two of the same part number.

Can I use this if my retainer bar keeps falling out?

Usually, yes—that's exactly what this part fixes. When the end cap cracks or breaks, the retainer bar has nothing to grip onto and slides right out. However, if the slots in your door liner are physically damaged or cracked, the new cap won't stay in place and you'll need door liner repair or replacement.

How long do these end caps typically last?

It depends on how much weight you put on your door shelves. Most last 5-8 years under normal use, but they can crack sooner if you're constantly slamming the door or overloading shelves with multiple gallon jugs. The plastic becomes brittle over time from temperature changes, which is why this is such a common failure point on older GE refrigerators.
