I had to drill out the screws on my large burner, thus destroying the orifice assembly for the large burner. I bought new burner, ignition tip assembly, and a new orifice assembly, but to install the orifice assembly, it appears I must remove the glass top to get inside. I have not removed any other burners (all those screws are rusted out as well, but they work….) I took the cooktop out of its mounting on my countertop, turned it over and removed every screw I could, but the glass top won’t come free. Must I remove the rest of the burners? How do I avoid destroying the burner/orifice assembly in the process?
Any other ideas?

Hi. Yes, it looks like you have to remove all the burners to remove the glass top. It shows on the parts break down I looked at, that the screws for the burners attach into the orifice holder assemblies, like you have stated. So the burners have to be removed to get the glass top off. When I have rusted screws like this I have used a couple of different methods. You can take a drill bit and drill the heads of the screws off, then you should be able to remove the burners. I do not think the burner holes that the screws to through are threaded. Should just be in the orifice holder that is threaded, so breaking the head of the screws off will allow you to remove the burners. Then after the burner and glass top is off you can apply some penetrating oil on the screws and use a pair of vise grips or pliers to turn the screws out. There should be enough left of the screw with just the heads gone to grip on to. You could also try a “screw out” or screw extractor tool.

What a disaster. I sheared off the heads of all the screws on all the burners. Figured I’d get the top off so I could fix the one burner, then deal with the leftover screw shanks. No such luck, the shanks somehow are still holding the burners in place, and I can’t drill ’em out (at least not so far…) So, I’ve decided to reassemble everything, put the cooktop back in place. Then, I’ll put the big burner back inplace (loosely held with the screw shank) and live with it until I can do replacement research. Recommendations on replacements (30″ downdraft)? So far, it looks like GE Profile or KitchenAid. KitchenAid has a nice strong burner, but a shitty reputation for quality. GE is more expensive. Thoughts?

I’m really sorry to hear this did not work for you. You could try a screw extractor, but it seems it would be difficult with the screws being so small. From what I have seen GE and Whirlpool are about the only companies to make downdraft units. Whirlpool includes Kitchen-aid and Jennair. Being in the field I do not see a big quality difference between the two brands. We repair one just as much as the other.
