Disconnect the power to the range, and ensure that all components are completely cool.
Open the oven door, then remove the two vertical bolts from under the front lip of the glass top.
Lift the glass top up from off the stove, then unscrew the two connectors on the brackets securing each burner to the glass top. Remove the burners, but do not disconnect the wires connecting the burners to the stove. If necessary, take a picture with a digital camera or draw a diagram of the connections for reference during reassembly.
Remove the screws securing the brackets that hold the burners to the glass if your replacement glass top does not include the brackets.
Lift the glass top off of the stove and set it aside once all of the components have been removed.
Install the brackets on the bottom of the new glass top if necessary. The brackets will screw into pre-drilled holes on the bottom of the glass top.
Place the new glass top on the range. Insert the back portion of the glass top that fits under the control panel first by placing the glass top on the range at a 45-degree angle.
Install the burners into the burner brackets on the new glass top, then lower the glass top into place on the range.
Secure the new glass top using the two bolts that were originally removed.
Close the oven door, then restore power to the range to complete the installation.
