My Samsung refrigerator RF267 series ice maker had stopped working. There was no ice build up, and it occasionally made a buzzing/whiring/grinding noise. It still had ice in the freezing tray, but the thermal resistor was bad. In this video, I show how to remove and replace the thermal resistor for a Samsung ice maker model DA97 07365A (DA9707365A, DA9707365G).
