When your Roper oven light won't turn off, the light switch is the most likely cause. A shorted light switch can continue sending power to the oven light even when the switch is in the off position. Test the switch for continuity with a multimeter and replace it if it shows continuity when off. If the light stays on when you press the control button, the touchpad and control panel may not be responding. Test the other buttons to see whether some work and others do not. A shorted oven control board can also keep the light on after the light switch is ruled out. Less common causes include a bent door hinge that prevents the door from closing tightly, or a shorted door switch on models that use the door switch to control the light. These issues explain why an Roper oven light stays on or the oven light is not turning off. Disconnect power before testing or replacing parts, and enter your Roper model number to find the exact replacement part for your range, stove, or oven.
