Instructions

 Warning: Undertaking repairs to appliances can be hazardous. Be sure to use the proper tools and safety equipment noted in the guide and follow all instructions. Do not proceed until you are confident that you understand all of the steps and are capable of completing the repair. Some repairs should only be performed by a qualified technician.

Step 1: Shut off power and gas

Unplug the power cord from the wall outlet and then close the gas supply shut-off valve.

Close the gas shut-off valve.

Step 2: Remove the burner heads

Remove all the cooktop grates and then lift the gas burner caps off the burner heads. Remove the screws that hold the burner heads in place and then remove the burner heads.

Step 3: Remove the main top

Pull the control knobs off of the burner control valves. Remove the screws that secure the main top to the top of the burner orifice holders. Lift the main top off of the cooktop and set it aside.

Step 4: Remove the spark igniter switches

 Tip: If the wire harness and switches are one component, as on this model, remove all the switches. On models with switches that can be removed individually, remove only the switch you're replacing.

Take a digital picture of the wires attached to the existing spark module or tag them with labeled masking tape so you can connect them correctly to the new spark module.

Disconnect all the wires attached to the spark module.

Remove the bushings from the stems of the burner control valves. Pull the spark igniter switches off of the burner control valves. Remove the switch and harness assembly from the cooktop and discard it.

Step 5: Install the new spark igniter switches

Push the new switches onto the stems of the burner control valves.

Reinstall the bushings on the burner control valve stems.

Using the digital picture or marked tape as a guide, connect the wires to the new spark module.

 

Step 6: Reinstall the main top

Position the main top on top of the burner orifice holders. Insert and tighten the screws that secure the main top to the orifice holders. Push the control knobs on the burner control valves.

Step 7: Reinstall the burner heads

Position the burner heads in the correct locations, screw them into place and tighten the screws firmly. Cover the burner heads with the burner caps in the correct locations. Set the grates into place on the cooktop.

Step 8: Reconnect the gas and power

Plug the power cord into the wall outlet and open the gas shut-off valve.
