That model number that you provided does not appear to be valid. You may have mis-keyed some numbers.
I provided a procedure for removing the main top on a typical Kenmore Elite gas range in the image below. If you have a range that is similar to that one, then you can use that information to remove the main top.
If you have a different type of range or you need more help, reply with additional details and an updated model number for your range.
If you get to the point where you need to have a service technician replace that top, you can schedule service through this link:
