Thanks for using this service. Please be logged in to rate my assistance when we are done. Rating 3-5 is good, but 1-2 is bad so talk with me first. On your model you have to take the burner grates off and the burner lids. There are screws in each of the 4 aluminum manifolds. You need to remove all of those and the top will lift off. That is the only way to get it off. Sometimes the screws get seized up so you may have to drill some of them out to get it off.
All I ask is that you rate my assistance thanks!
after taking grates ,lids ,manifold off and prying with screwdriver there is resistance to top lifting, am i doing something wrong?
