The reset button is located on the front of the ice maker. The locations of these buttons vary depending on the model but for most models, it is located near the ice bin and can be found by turning off your refrigerator and then looking for a small round red button (usually with an arrow pointing to it). The next step would be to press this button so that you can reset your ice maker. Make sure that you do not press any other buttons or switches while doing this as they may also cause damage to your refrigerator's mainboard and/or compressor unit.
