The Samsung DG94-03500V Range-Knob Assembly is a convenient part for the cooktop as it allows to have full control of the heat levels for cooking needs. This will provide the necessary replacement to get the range back up and running better. Just turn the knob over the control shaft and it fits better to enable the control of burner temperatures. https://www.hnkparts.com/dg94-03500v-smg-knob-assy
