Whirlpool, KitchenAid, Jenn-Air & Maytag Ice Maker Shut-Off Arm Extension Parts — Models & Compatibility

If your ice maker won't stop producing ice or won't shut off when the bin is full, you're likely dealing with a faulty shut-off arm extension. This small but critical component tells your ice maker when to stop — and when it fails, you'll find ice overflowing onto your freezer floor or no ice production at all. The W11215550 shut-off arm extension works across multiple premium brands including Whirlpool, KitchenAid, Jenn-Air, and Maytag refrigerators.

Is This the Right Part for Your Model?

The W11215550 fits a wide range of side-by-side and French door refrigerators manufactured by Whirlpool Corporation brands. You'll find your model number on a sticker inside the fresh food compartment — usually on the left or right wall, just above the top shelf. Check your model against the compatibility list below before ordering. This part replaces older numbers 2304353, 4844535, W11112558, AP6329225, and PS12349375, so if you've seen any of those references, you're in the right place.

About This Replacement Part

The shut-off arm extension is the mechanical linkage between your ice bucket and the ice maker control. When ice fills the bin and pushes the arm upward, it signals the ice maker to stop production. Over time, the plastic arm can crack, break at the pivot point, or simply wear out from repeated cycling. When this happens, the ice maker either runs continuously (because it never gets the "stop" signal) or won't produce ice at all (if the arm is stuck in the "off" position). The W11215550 is an OEM-quality replacement designed to restore proper shut-off function. Installation typically involves removing the ice bin, unclipping the old arm extension, and snapping the new one into place — no special tools required for most models.

Compatible Refrigerator Models

This shut-off arm extension is confirmed compatible with the following models. If your model isn't listed but shares the same series designation (like ED5, JB36, or MFI2), it's likely compatible — verify the part number match in your refrigerator's tech sheet or parts diagram.

Installation Overview

Replacing the shut-off arm extension is one of the simpler ice maker repairs. Start by removing the ice bucket from the freezer. Look for the arm assembly on the left side of the ice maker housing — you'll see where the extension connects to the control arm. Most designs use a simple clip or snap-fit connection. Pull the old extension straight out (you may need to depress a locking tab), then align the new W11215550 and press firmly until it clicks into place. Test the movement by manually raising and lowering the arm — it should move smoothly without binding. Replace the ice bin and monitor for proper shut-off over the next 24 hours.

When to Replace This Part

Replace the shut-off arm extension if you notice ice overflowing from the bin onto the freezer floor, ice production that won't stop even when the bin is full, or an ice maker that won't produce ice despite having water supply and power. Physically inspect the arm for cracks, especially near the pivot points or where it connects to the control mechanism. If the arm feels loose or doesn't spring back to the down position when released, replacement is needed. This part typically fails due to age-related plastic fatigue rather than a specific trauma event.
