Oven light won't shut off

I have a Maytag Gemini Smoothtop Double Oven range. Says it is a Precision Touch 750 series. The small halogen oven light in the upper oven burned out. I replaced it. It will not shut off. I have shut the oven light switch off and on, off and on. I have turned the breaker on and off. The oven door switch goes in and out just fine. Anybody have an answer to this?

Did you change the light out with the range plugged in?

I did exxactly this. Is there a way to fix this?

Thanks
