Please provide me detailed instructions on how to install this part and remove the old one.
Answer Hello Billie,
The most important step is first. Disconnect electrical power to the unit, (many times on a gas unit there will actually be a receptacle under the cook top where you can just un-plug the unit). Reach under the unit and turn off the gas, (there should be a big gas shut-off valve). Set the grates aside and I always set the burner caps aside in order so they get reinstalled in the same position they were removed from. Some of these require that the cooktop be lifted out of the hole and set diagonally over the hole as the top edges support the units weight. Use some towels to prevent damage to the countertop. On these, if you remove the top with the unit in place, since the edges of the top support the entire cooktops' weight, it will drop down through the hole into the cabinet.
Now you will need a magnetic bit and always be careful not to drop the screws (this is a bit more important during reassembly to prevent the necessity of re-disassembling to retrieve a dropped screw). These screws are located under where the burner caps were (two per burner). Once they are removed and the knobs are removed, the main top should lift off.
Be sure at this point that if there are grommets around the knob holes or any other small parts, you remove them and install them onto the new top. Reassembly is of course in the reverse order.
Be sure not to cross thread any of the screws. I found that it's best to start the screws by hand to prevent this. These screws are tempered to withstand temperatures and they twist off easily. Before reinstalling the burner screws it's a good idea to put some white lube on the threads as the heat they are exposed to will make them seize. This is a big issue if you ever attempt to remove them again. Good luck and remember, it's better to wear gloves than to get stitches!
