Christina H Spring Lake , MI March 04, 2016 Replaced glass top and grease filter Bought a new filter to replace. Very easy. Also bought a new glass top for my Jenn Air cooktop. That was easy as well. Unscrewing 7 bolts with 1/4" nut driver, removed and put new one on. It's like a new cooktop now! Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
