A replacement spark ignition module that delivers timed high-voltage pulses to burner electrodes so gas burners light reliably. Replaces a failed ignition control to restore normal spark operation for cooktops and ranges. What it does

  • Sends spark to the burner electrodes so gas ignites when a burner is turned on — use when burners fail to light or need multiple tries.
  • Routes spark to the correct burner circuit based on the range's control settings.
  • Helps prevent continuous sparking when the burner is off by switching ignition output as commanded.
  • Works with existing electrode wires and control harnesses when the original module fails.
What's included One replacement spark ignition module. Install notes
  • Disconnect electrical power and shut off the gas supply before starting any work.
  • Handle electrode wires and connectors gently; avoid crimping or bending electrode tips.
  • Verify wiring matches the old module exactly; tag wires if needed to ensure correct reconnection.

Questions & Answers

For Ge Spark Ignition Module (Replacement Kit) (Part Number: OEM21538563)

1 Answer

Roger, based on the information provided, it sounds like one of the burner switches has failed and has constant continuity when it should not while the burner is off. Unfortunately, both switches used with the model provided, WB24K10023 and WB24K10024, have been discontinued by the manufacturer and are no longer available. Switch failures like this have the potential to cause the spark module WB13X42446 to fail as well and no longer allowing any burners to spark.

Alan, With the 2 terminals for the l1 and neutral closest to you then the L1 will go to the left and the Neutral will go to the right.

Hello John. Yes, it is the correct spark module. You will access your old module behind the control panel. Replace the part. If the igniters need replaced, you can use the ones sent in the kit. If your old ones are good, you can use them.

George for Model Number JGBP32DEM1WW

One of my 4 stove ranges does not seem to be working. The gas ignites with a match. I tried to replace the electrode with a new one and one from one of the working ranges. Also tried changing the wiring from one of the working ranges (the not working wire worked on another burner). The clicking sound goes off but I am not able to see a spark on the non-working range. Is it possible I need to replace the Spark Module? Is there a way to test that particular part to see if that is it? Thanks again for all your help.

1 Answer

George, You will want to check the ignition switch for that burner with a continuity tester. When the switch is in the on position there should be continuity across the switch and if not then the switch is bad. If the switch checks ok and the electrode has already been replaced then the spark module will most likely be the issue.

Dick, If the ignitor is sparking then you will want to check the burner to make sure that the holes for the gas to flow out of are not clogged up and check to make sure that the ignitor is in the correct position.

Russ, You're on target. You most likely have a failed spark module WB13K25 or a damaged wire to the module. Good Luck and Thanks
