A Whirlpool WFG320M0BW gas oven that won’t ignite leaves you without a working oven — frustrating, especially if you’re cooking for a family. We serviced this exact issue for a homeowner in Plant City, FL. The fix required diagnosing which ignition component failed, since “won’t ignite” can mean several different things on a gas range.
Why Won’t My Whirlpool Gas Oven Ignite?
- Weak or failed oven igniter — This is the most common cause on Whirlpool gas ovens. The igniter does double duty: it glows to ignite the gas AND it opens the safety gas valve. When the igniter weakens (typically 2.5–3.2 amps — it needs 3.2+ to open the valve), the oven won’t ignite even though the igniter appears to glow.
- Dirty or clogged burner tube — If food debris or grease has clogged the burner tube holes, gas can’t distribute evenly and ignition fails. You may smell gas without a flame forming.
- Failed safety gas valve — Rare but possible. If the valve won’t open regardless of igniter current, no gas reaches the burner.
- Broken wire harness to igniter — The connection from the control board to the igniter can burn or break over time from repeated heat cycling.
- Control board fault — Least common. If the board isn’t sending the bake signal, the igniter never activates.
What Our Technician Found on the WFG320M0BW
Our tech tested the igniter with a multimeter and found it drawing 2.1 amps — significantly below the 3.2 amp minimum needed to open the safety gas valve. The igniter was glowing orange (appearing to work) but not producing enough current. This is the most common failure mode on Whirlpool gas ovens — the igniter looks like it’s working but isn’t strong enough.
We replaced the igniter with OEM Whirlpool part W10918546 and tested the oven through a full preheat cycle to 400°F. The oven ignited immediately within 60 seconds and maintained temperature accurately. Total on-site time: 55 minutes.
How to Tell If Your Whirlpool Oven Igniter Is Failing
- The oven takes 5+ minutes to ignite (or never ignites)
- You can see the igniter glowing orange but the burner doesn’t light
- You smell gas for a long time before the oven ignites (the valve is barely opening)
- The oven ignites sometimes but not others
