just done mine, unscrew top at back from l brackets, then take out all small screws from burner tops, the front either side is on pins and need a good tug up to pop out, top then comes off. unscrew 4 screws holding burners to side panels, lift up , screws out of plate underneath and wangled things out from there. mine had just come off the spindle and went back on. good luck
