While trying to access and clean brass jet orifices I wrenched the brass nut with chamfer too much (it was seized) and twisted the jet holder to the breaking point and collapsed the main front tubing. I had to hacksaw the rest off. After receiving replacement parts from APPs I was able to reassemble everything in a half hour or so. I lifted the unit countertop height and bridged my cutout with a couple of 2x4's to set it on. From there it was outside trim removal (about 20 screws) then you can remove the other burner tube, igniter, and burner pan. At that point you have wrench access to the tubing nuts and the rest is just remembering how you took stuff apart. Pretty easy since you have other burners for reference. $102 vs $2000 for a new top. I'm a fairly handy guy but I've never done this before. Also took the opportunity to clean everything good before reassembly. 8 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
