The shutoff arm in an ice maker is a crucial component that helps control the ice-making process. It detects when the ice bin is full and prevents the ice maker from producing more ice. If the shutoff arm is not functioning correctly, it can lead to overproduction of ice or the ice maker not working at all.
Caution
Please read our safety information before attempting any testing or repairs.
Steps to Check the Shutoff Arm
- Safety First:
- Unplug the refrigerator or shut off the power at the fuse box or breaker panel to avoid an electrical shock hazard.
- Locate the Shutoff Arm:
- The shutoff arm extends away from the ice maker over the ice cube bin. It rises and falls during each ice-making cycle.
- The arm should be securely supported at one or both ends. One end extends into the back of the front support.
- Inspect the Shutoff Arm:
- Confirm that the arm is securely in place in its support.
- Ensure that the arm can move freely and is not obstructed by ice or any other objects.
- Manual Shutoff Test:
- To manually turn off the ice maker, lift the arm all the way up into the locked position. This should stop the ice maker from producing more ice.
- Leave the arm in the up (off) position and recheck the ice maker after a few hours to ensure that no new ice is being made.
- Functionality Check:
- Lower the arm to the operational position and make sure it can move up and down freely.
- Ensure that nothing is blocking the arm from moving normally during the ice-making cycle.
- Observation:
- Watch the ice maker through a cycle to confirm that the arm rises and falls correctly. When the arm cannot drop because of accumulated ice in the bin, it should stop the ice-making process.
Troubleshooting
- If the Arm Does Not Stay in Place:
- Check that it is properly aligned in its support.
- If it is loose or damaged, it may need to be re-secured or replaced.
- If Ice Maker Continues Making Ice with Arm in Off Position:
- The control module may be faulty and need replacement.
Diagnostic Table
- Issue: Ice maker continues making ice even with the shutoff arm in the up position.
- Solution: Replace the control module (for modular units).
By following these steps, you can ensure that the shutoff arm of your ice maker is functioning correctly, preventing overproduction of ice and ensuring the smooth operation of your ice maker.
