How to Replace a Range Spark Igniter Switch



This DIY repair guide shows how to replace a spark igniter switch in a freestanding gas or dual-fuel range, but can be adapted to a built-in range as well. If the surface burner won't spark when you turn the burner control knob to the Lite position, or if the igniter clicks constantly even when the burner is off, then replace the burner igniter switch using a manufacturer-approved replacement part.

This repair procedure covers many Kenmore, Frigidaire and Electrolux gas ranges. You also can use the same basic process to replace spark igniter switches in GE, Whirlpool, KitchenAid, Maytag, Amana, Bosch, Samsung and LG gas ranges.

Tools Required

  • 1/4" nut driver
  • Phillips screwdriver
  • Slot screw driver
  • Work gloves

Before you begin

Wear work gloves to protect your hands from sharp edges.

The cooktop and grates must be cool to the touch.

You might need an assistant to help remove the cooktop.


 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

If necessary, pull the range away from the wall to get access to the power outlet and gas supply valve. 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 grates, burner caps and burner heads

Remove all the cooktop grates and then lift the gas burner caps off the burner heads. Set these parts aside.

Using a 1/4" nut driver, remove the screws that secure the gas burner heads in place. Remove the burner heads from the cooktop.

 Tip: Mark the burner caps with a note indicating their location (Left Front, Right Front, Left Rear, Right Rear).

Step 3: Remove the cooktop

Remove the screws that secure the top of the cooktop to the top of the burner orifice holders. 

To pop the cooktop out of the 2 mounting clips under its front edge, position a slot screwdriver or stiff putty knife between the front of the range frame and the cooktop, about 3" from the side of the range. Push the tool straight into the gap and lift slightly to release the clip that holds that side of the cooktop. Repeat for the other side.

Lift the front of the cooktop and then carefully remove the cooktop without disturbing the burner orifice holders. Set the cooktop aside.

Step 4: Remove the control manifold

Open the oven door fully and remove the screws that are under the control manifold.

Pull the control knobs straight off the stems of the gas burner control valves on the front of the control manifold.

Remove the screw that's behind each clip on top of the control manifold.

Lift  the control manifold off  the gas range. Take care to not lose the mounting clips, which are loosely attached to the top of the control manifold.

 Tip: You should be able to remove the screws with a Phillips screwdriver. The fastener heads vary by model.

Step 5: Remove the spark igniter switch

Pull the spark igniter switches off  the front of the burner control valve stems. Don't pull out the wire harness yet.

 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.

Pull the spark igniter switch off the stem of the burner control valve.

Step 6: Remove the upper back panel

Remove screws from the upper panel on the back of the range and then pull the upper back panel off the range. As you remove the last screw, press on the upper back panel to prevent it from dropping.

 Tip: The number and location of the screws on the upper back panel vary by model.

Step 7: Disconnect the wire harness

Disconnect both red wires from the spark module.

Pull the wire harness out through the front of the gas range,

 Tip: Some models require removing the lower back panel to access the wires on the spark module. On other models, the spark module is under the cooktop or behind a side panel.

Step 8: Connect the new spark igniter switches

Push the new spark igniter switches onto the front of the gas control valves, with the long tail of the wire harness on the right  (as you face the range) so  it can reach the spark module.

Push the wire harness through the opening on side of the frame to the back of the gas range.

Connect the wires to the spark module. One wire has a spade connector that pushes onto a spade at the top of the spark module. The other wire has a white plastic connector that plugs into the red wire below the spark module.

Step 9: Reinstall the front control manifold

Position the control manifold on the front of the gas range.

Make sure the mounting clips are in place and then install  the screws behind the mounting clips on the top of the control manifold.

With the oven door open, install the screws at the bottom of the control manifold. Tighten all  the mounting screws firmly.

Step 10: Reinstall the control knobs

Position the knobs on the front the of the burner control valve stems and push them down fully.

Step 11: Attach the back panel

Position the upper back panel on the back of the range and hold in in place while inserting the first screw or two. Insert all  the screws and tighten them firmly.

Step 12: Reattach the cooktop

Position the cooktop on the top of the range and snap it into the mounting clips on the front lip of the range.

Insert the screws into the holes that secure the cooktop to the gas burner tube orifice holders. You may need to move the burner tube orifice holders around slightly to line up the holes and insert the screws. Tighten all screws firmly.

Step 13: Reinstall the burner heads, burner caps and grates

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 14: Reconnect gas and power and slide the range into place

Plug the range back into the wall outlet and the open the gas supply valve. 

Slide the range into position, making sure the rear foot of the range properly engages the anti-tip bracket.

 Warning: The anti-tip bracket must be properly engaged so the range won't tip forward. Refer to the installation instructions for details about the anti-tip bracket.
