Kenmore Oven Clicking but Won’t Light — What’s Happening
When your Kenmore oven clicks but won’t light, you’re hearing the ignition system trying to start the burner but failing to complete the cycle. On ovens with a hot-surface igniter, the igniter may glow orange or red but never draw enough current to open the gas safety valve, so no gas flows and no flame appears. On spark-ignition models, the clicking is the spark module firing repeatedly, but ignition fails because of a problem with the spark electrode, gas flow, module, or wiring.
If the igniter glows bright cherry red and the burner still doesn’t light within one to two minutes, the igniter is likely weak or the gas valve circuit has failed. If you hear clicking with no glow or spark visible, the issue is usually electrical, involving the spark module, control board, or damaged wiring between components.
Most Likely Causes
- Weak or failed oven igniter The igniter glows but doesn’t pull enough current to open the gas valve, typically needing 3.0 to 3.6 amps to trip the valve open.
- Bad spark module On spark-ignition ovens, a failed module will click repeatedly but won’t produce a strong enough spark to ignite gas at the burner.
- Faulty gas safety valve The valve coil can fail open, preventing gas from flowing even when the igniter or spark system is working correctly.
- Loose or heat-damaged wiring Broken connections or damaged harnesses between the igniter, valve, module, and control board interrupt the ignition circuit.
- Failed control board A bad relay or burned circuit on the main board can prevent the ignition command or power from reaching the igniter or spark module.
- Gas supply issue If the supply line, regulator, or shutoff valve is closed or restricted, no gas reaches the oven even though the ignition system fires.
- Cracked spark electrode or damaged ceramic On spark systems, a broken electrode won’t arc properly, and the spark shorts to ground instead of jumping the gap to ignite gas.
How to Diagnose and Fix
- Identify whether your oven uses a hot-surface igniter that glows or a spark-ignition system that clicks, by watching the start cycle.
- Test the cooktop burners to confirm gas is reaching the range. If the cooktop also won’t light, check the supply line and shutoff valve before proceeding.
- For glow-bar systems, observe whether the igniter glows bright cherry red. If it glows dim or orange but never lights within one to two minutes, suspect a weak igniter.
- Measure igniter current draw with an amp clamp if equipped. Readings below 3.0 amps are suspect and below 2.6 amps indicate a failed igniter that must be replaced.
- Test the gas safety valve for continuity. An open-loop or infinite resistance reading means the valve coil has failed and the valve assembly should be replaced.
- Inspect the igniter connector, mounting bracket, and wiring harness for loose terminals, cracks, or heat damage. Replace any damaged wiring or connectors.
- On spark-ignition models, check the spark electrode and module for cracked ceramic, corrosion, or loose wiring. Replace the electrode or module if damaged.
- Check the main control board for burned relays, scorch marks, or no output voltage to the ignition circuit if all ignition components test good.

When to Call a Pro
Call a qualified appliance technician for all work involving gas connections, burner removal, or gas valve replacement. Testing and replacing igniters, spark modules, and wiring can be done by experienced DIYers with the gas supply shut off and the range unplugged, but any repair that requires disconnecting gas lines or diagnosing control board output voltages is best handled by a pro. If you smell gas at any point, stop work immediately, shut off the gas supply, ventilate the area, and call for service. For gas line, burner, or igniter work, or if you ever smell gas, stop and call a licensed technician.
