When your Samsung oven light won't turn off, the light switch is the most likely cause. The switch sends power to the oven light, and a shorted switch can keep the light on even when the control is set to off. Test the switch for continuity with a multimeter and replace it if it has continuity in the off position. If the oven light stays on when you press the light button, the touchpad and control panel may not be registering the command. A defective touchpad can cause the same oven light not turning off problem. If the light switch and controls check out, a shorted oven control board may be supplying power continuously. Less commonly, a bent door hinge can prevent the door from closing tightly enough to activate the light switch, or a failed door switch can remain electrically closed. Check that the door closes fully and does not open past 90 degrees. Before ordering, enter your Samsung range, stove, or oven model number to find the exact replacement light switch, touchpad, control panel, control board, door hinge, or door switch for your appliance.
