Understanding the Problem
The ignition (spark) module on GE Profile gas ranges controls the high-voltage pulses that create sparks at the burner electrodes. When the module fails you may hear clicking but see no spark, experience weak or intermittent sparking, or have only some burners ignite. Many failures are caused by shorted outputs inside the module, moisture, cracked electrode leads, or a worn-out module after years of use. Diagnosing the ignition module requires checking the obvious items first (clean, intact electrodes and properly seated burner caps), then verifying voltage and continuity to isolate the module. In many cases the module is the culprit, but wiring harness damage or faulty burner electrodes can produce identical symptoms. Always verify model compatibility before ordering a replacement module and shut off power and gas before testing or replacing parts.
Common Symptoms
Continuous clicking with no flame, intermittent sparking, only one or some burners ignite, or the range fails to ignite after a power surge or moisture exposure.
Common Causes
- Failed internal electronics in the ignition (spark) module
- Cracked or corroded burner electrodes or damaged electrode wires
- Moisture, grease buildup, or a shorted wiring harness causing intermittent operation

Helpful Repair Tip
Confirm the module is faulty by cleaning and testing electrodes first, then use a multimeter to check for 120VAC to the module and for a pulsed high-voltage output while a burner is turned on; if inputs are present but no output, the module is likely bad.
Frequently Asked Questions
How do I test whether the ignition module is bad?
First, ensure electrodes and burner caps are clean and properly positioned. Turn power and gas off before inspecting. With power on and a knob turned to light, use a multimeter to confirm 120VAC is reaching the ignition module input. Then, carefully observe for spark at the electrode (or use an insulated tool) while the module is energized. If the module receives input power but produces no spark at any output terminal, the module is likely defective. For a safer/no-spark test, replace the electrode and harness first, as those are inexpensive compared to the module.
Can I replace the ignition module myself and how hard is it?
Yes — many homeowners can replace the ignition module if they are comfortable disconnecting power, removing the cooktop or lower access panel, and unplugging the module harness. Turn off power at the breaker and gas supply first. Label connectors before disconnecting to ensure correct reassembly. If the module is behind the control panel, access may require removing knobs and the control panel. If you're unsure, hire a qualified appliance technician to avoid gas or electrical hazards.
