If the ice maker on your Samsung RF18HFENBWW refrigerator continues to turn on and off despite not being hooked up, it's possible that the switch or sensor controlling the ice maker is malfunctioning. You may need to replace the ice maker assembly or have a technician look at it.
In the meantime, you can try turning off the ice maker manually by following these steps:
- Open the refrigerator door and locate the on/off switch for the ice maker. It should be located on the control panel inside the fridge.
- Switch the ice maker to the "Off" position.
- Unplug the refrigerator from the electrical outlet for 30 seconds and then plug it back in. This will reset the control panel and may help stop the ice maker from turning on and off.
If these steps do not work, it's best to contact Samsung customer support or a qualified technician to diagnose and fix the issue.
