cracked gas tubes

My front burners were inoperative because the metal gas lines under the cooktop were cracked. This happened because I tried to remove the cooktop without properly removing the screws holding the assembly to the cooktop. Doh!

Anyway, this is an easy fix. First, remove the 4 burner tops by rotating them counterclockwise and lifting them out of the cooktop. Then, remove the two ignitor wires from each burner, and set the burners aside.

Next, remove the four small screws that hold the burner tube assemblies to the underside of the cooktop. There is one screw near each burner hole in the cooktop (the screws are covered when the burner tops are installed). You must remove all four screws even if you are only installing one replacement orifice and tube kit!

Now you can tilt the cooktop up and remove it from the stove, exposing the orifice and tube assemblies. Use an adjustable wrench to loosen the brass nuts connecting the gas tubes to the valves, and remove the assembly.

Reassemble in reverse order.

If you have "high speed" burners, remove the orifice that comes on the unit and replace it with the loose orifice that is in the packaging.
