My Kenmore dual electric range inner element problem

My Kenmore Model #79094192315 Right inner range element does not work consistently.

Turning it on high, seems to work. When I turn the # 316238201 element switch to a lower setting it will work sometimes. other times it seems to go off until I turn it on high. The dual element side works fine.

The switch is acting up. Here is the part number, 316238201 Electric Range Surface Element Control Switch | Genuine Frigidaire OEM In Stock
