GE Oven Spark Module Replacement - Signs & How-To

GE Oven Spark Module Replacement — What This Part Does

The spark ignition module generates the high-voltage pulses that create a spark at each surface burner igniter when you turn a burner knob. It sends current to the igniter electrodes so gas lights when you open a valve. The module typically mounts on the rear panel behind the cooktop and connects to all burner igniters through a wire harness.

Modules fail from age, moisture intrusion, or electrical shorts. When the module goes bad, burners won’t light because there’s no spark. In some failure modes the entire cooktop may spark continuously even when burners are off. Grounding issues, dirty burner components, and damaged wiring can mimic module failure, so check those first before ordering parts.

Jump to Replacement Steps

Signs It Needs Replacing

• No spark at any burner You turn a burner knob and hear gas but see and hear no clicking spark at the igniter, so the burner won’t light.
• Only some burners spark One or two burners ignite normally but others produce no spark, even though gas flows.
• All burners spark continuously The cooktop clicks and sparks nonstop, even when all knobs are off (though the spark ignition switch is a more common cause for this symptom and should be tested first).
• Weak or intermittent spark You see a faint or inconsistent spark that won’t reliably light the gas.
• Burners light only with a match Gas flows normally but you have to use a lighter or match every time because the igniter produces no spark.
• Spark stops after cleaning spills After a boil-over or cleaning, one or more burners stop sparking (grease or moisture may have damaged the module or its connections).

How to Replace It

1. Turn off the circuit breaker or unplug the range, and close the gas shutoff valve to the appliance.
2. Remove all grates, burner caps, and burner bases from the cooktop.
3. Remove the screws securing the cooktop (usually along the front edge and sides, sometimes through orifice-holder brackets).
4. Lift the main cooktop up and prop it open to access the underside and rear panel where the spark module is mounted.
5. Take a photo of all wire harness connections on the old module so you know exactly where each wire plugs in.
6. Disconnect each wire harness from the spark module by gently pulling the connectors straight off the terminals.
7. Unclip or unbolt the old module from its mounting bracket on the rear panel and remove it.
8. Snap or bolt the new spark module into the mounting bracket in the same position as the old unit.
9. Reconnect each wire harness to the corresponding terminal on the new module, matching your photo and any color or position marks.
10. Lower the cooktop back into place, making sure all igniters protrude correctly through their holes in the cooktop surface.
11. Reinstall all cooktop screws, burner bases, burner caps, and grates.
12. Open the gas valve, restore power at the breaker, and test each burner for proper spark and ignition.

When to Call a Pro

If burners spark continuously, test or replace the spark ignition switch before the module, since the switch is the more common cause of that symptom. Any work involving gas line connections, burner orifice removal, or gas pressure testing should be performed by a qualified appliance technician or licensed gas fitter. Call a pro if you’re uncomfortable working around gas appliances, if the new module doesn’t solve the problem, or if you find damaged wiring or corroded terminals that suggest deeper electrical faults. For gas line, burner, or igniter work, or if you ever smell gas, stop and call a licensed technician.
