Understanding the Problem
When a Whirlpool gas oven won’t light the problem usually points to the ignition system or the gas supply. Modern Whirlpool ovens either use a glow igniter that heats and opens a gas safety valve or a spark ignition system that creates sparks at the burner. If the igniter doesn't glow, the spark module doesn't click, the gas valve doesn't open, or the burner ports are blocked, the oven will fail to light. Less commonly, the cause can be a closed gas supply, a failed safety thermocouple (on older pilot systems), a malfunctioning oven control board that won't send the ignition signal, or a clogged burner/dirty orifice. Diagnosing usually starts with observing what happens when you try to ignite the oven (glow, click, smell of gas) and then isolating the component that isn’t doing its job.
Common Symptoms
No glow from igniter, no clicking spark, gas smell with no ignition, burner never lights, oven lights briefly then shuts off, or clicking that doesn’t produce a flame.
Common Causes
- Failed or weak oven igniter (most common)
- Faulty spark module or electrode assembly (spark ignition models)
- Defective gas safety valve or gas supply issue
- Blocked burner ports or dirty orifice
- Faulty oven control board or wiring harness
- Old pilot/thermocouple failure (on older models with standing pilot)

Helpful Repair Tip
Watch what happens when you press BAKE: if the igniter glows weakly or never glows the igniter is usually the problem; if you hear clicking but no spark, check the spark module and electrodes; if you smell gas but no ignition, stop and call a technician.
Frequently Asked Questions
My oven clicks but doesn't light — can I fix the spark module myself?
If you hear clicking but no spark and you're comfortable with basic appliance repair, you can visually inspect the electrode tips (clean any carbon buildup), verify wiring connections to the spark module, and replace the spark module or electrode assembly if visibly damaged. Always disconnect power (and gas if working on components that may leak) before servicing. If troubleshooting shows the module isn’t sending voltage to the electrodes or you’re unsure, hire a qualified technician because gas and ignition systems are safety-critical.
How do I confirm the igniter is bad?
Start by watching the igniter when you set the oven to BAKE: a good glow igniter should glow bright orange within a few seconds and then the burner will light. A weak igniter may glow dimly or slowly (or not at all) and the burner won’t light. For a more definitive test, a technician can measure current draw — a weak igniter won’t draw the required amperage to open the gas valve. You can also check for continuity with a multimeter (no continuity indicates a failed element). If the igniter appears dim or fails continuity, replacement is usually the fix.
