Our black Jenn-Air Expressions downdraft cooktop is 19 years old. It still works great, but the air grill had seen better days (peeling finish) and the downdraft ventilation filter was simply nasty. No matter how many times I've soaked and scrubbed it, I've never been able to get rid of that old, rancid grease smell. We've just updated our kitchen with new stainless Jenn-Air appliances, but I didn't want the maintenance of a stainless cooktop. Until I can find a suitable replacement, I just decided to replace the air grill and ventilation filter and my old cooktop looks (and smells) almost new! Both were a perfect fit...no tools required. Thanks for making it so easy to identify what parts I needed. I was amazed at how quickly I received my order, too.
