The Samsung DG94-03950B Range Knob Assembly is a replacement control knob used to regulate heat settings on compatible Samsung cooking ranges. This component connects to the control shaft on the front panel and allows users to adjust the burner or oven temperature by turning the knob to the desired setting. It operates by transferring the user’s rotation to the internal control switch, which manages the heating level of the selected cooking element. Installed on the range control panel, the knob fits onto the stem of the switch and engages with the regulating mechanism inside the unit. By supporting accurate temperature regulation and restoring normal control access, this part assists in maintaining stable cooking conditions during typical kitchen use.
