GE Gas Range Spark Ignition Switch Replacement — What This Part Does
The spark ignition switch mounts on the burner valve stem under the knob and closes an electrical circuit when you turn the knob to LITE. When closed, it sends voltage through the harness to the spark module so the surface burner igniter clicks and lights the gas. Over time the internal contacts wear or the harness connection loosens, and the switch stops reliably closing the circuit.
When the switch fails, you get no spark at all, intermittent sparking, or continuous clicking even after you release the knob. This is a mechanical and electrical switch problem in the surface burner ignition circuit, not an oven igniter or flame sensor issue. GE sells the switch as a separate replacement part along with the harness assembly.
Signs It Needs Replacing
- No spark when knob turned to LITE You turn the burner knob to the ignition position and hear or see nothing from the igniter.
- Intermittent or weak sparking The igniter clicks a few times then stops, or only sparks if you wiggle the knob.
- Continuous clicking after knob released The igniter keeps sparking and clicking even after you move the knob past LITE or turn it off.
- One burner won’t spark but others work Only the burner controlled by the suspect knob has no spark, which points to that switch and harness.
- Knob feels loose or does not click positively The knob has excessive play or the switch actuation feels mushy or broken when you turn to LITE.
- Visible heat damage or loose wires at the valve stem You see melted insulation, scorched terminals, or a loose connector on the switch harness behind the control panel.
How to Replace It
- Unplug the range from the wall outlet or turn off the circuit breaker, then shut off the gas supply valve to the appliance.
- Remove the burner grates, caps, and heads from the cooktop and set them aside.
- Remove the control knobs by pulling them straight off the valve stems.
- Remove the screws securing the front control panel or cooktop trim (locations vary by model) and lift or tilt the panel to access the valve stems and switches behind.
- Locate the spark ignition switch on the valve stem of the problem burner and disconnect the wire harness plug from the switch.
- Remove the mounting screw or clip holding the old switch to the valve stem bracket, then pull the switch off the valve shaft.
- Install the new spark ignition switch onto the valve shaft, secure it with the mounting screw or clip, and reconnect the wire harness plug until it clicks.
- Reinstall the control panel or trim, replace the knobs, and set the burner caps and heads back in place.
- Restore gas and electrical power, then turn the repaired burner knob to LITE and verify a steady spark and normal ignition.

When to Call a Pro
If you are not comfortable working with gas appliances, call a tech to handle gas shutoff, valve access, and leak testing after the repair. If the new switch does not fix the problem, the spark module or main wire harness may be faulty and a tech with a multimeter and wiring diagram can trace the circuit and test for voltage at the switch terminals. Any time you smell gas or suspect a leak, shut off the gas supply immediately and call a qualified service technician or your gas utility. For gas line, burner, or igniter work, or if you ever smell gas, stop and call a licensed technician.
