Symptoms
- Arm won't move up or down by hand
- Ice maker never fills or never stops filling
- Ice buildup around the arm mechanism
- Bin overflows or stays empty despite normal freezer temperature
Likely causes
- CommonIce or frost jamming the arm mechanismBuildup around the pivot point physically prevents the arm from moving.
- CommonArm manually left in the up (off) positionIt's easy to bump the arm up while loading the bin or cleaning, which pauses production.
- PossibleWorn or broken internal linkageThe mechanism connecting the arm to the control module can wear out or crack over time.
- Less commonFailed ice maker moduleEven with a freely moving arm, the module itself may not be responding correctly.
What to do
- Unplug the fridge or freezer before working near the ice maker mechanism.
- Look closely at the arm for visible ice or frost and gently clear it with your fingers or a warm cloth.
- Move the arm by hand through its full range to confirm it moves freely once cleared.
- Plug the unit back in and lower the arm to the on position, then watch a cycle or two.
- If the arm moves freely but ice production still doesn't respond correctly, the internal linkage or module may be at fault.
- Consider replacing the whole ice maker assembly if it's an older, failure-prone model, which is often more cost-effective than individual parts.

When to call a pro
If the arm moves freely but the ice maker still won't cycle correctly, an appliance technician can test the control module.
