Whirlpool Stove Not Lighting: Ignition Failure Fix
Quick Answer
A Whirlpool stove that fails to light is usually caused by a weakened glow-bar igniter or a clogged burner port. If the igniter glows but no flame appears, the safety valve is likely not receiving enough amperage to open properly.
Most times I pull up on a no-heat call for a Whirlpool gas oven, the igniter's sitting there glowing like everything's fine. That's exactly what makes this tricky. If you keep trying to run the oven with a weak igniter, you're filling a warm cavity with unburned gas, which is genuinely dangerous. Catch it early and you're usually looking at a $30-$60 part and an hour of your Saturday.

What Does the IGNITION-FAILURE Code Mean?
Nine times out of ten it's a weak igniter, not some fancy control board issue. These igniters weaken slowly over time and they'll glow just fine but can't pull enough current to actually trip the gas valve open. I replaced three of these last Tuesday alone. Start with gas supply and 120V at the outlet, then work your way to the igniter amperage test, which is where most people skip ahead and miss the real problem.

Symptoms You May Notice
You set the oven to Bake at 350 and ten minutes later it's still cold with no flame, just a faintly warm cavity
There's a noticeable gas smell coming from the oven or cooktop area but nothing ever ignites
Surface burner knob clicks rapidly when you turn it to Lite but the flame won't catch, or it lights for half a second then dies
Igniter is clearly glowing orange at the bottom of the oven but the burner never fires up
Complete silence when you turn a surface burner knob, no clicking at all
Can you reset a Whirlpool oven to clear the IGNITION-FAILURE code?
Unplug the range completely and wait a full 5 minutes. This clears any lockout state the control board might be holding onto. Plug it back in, let the clock come back up, and then try Bake again. For surface burner ignition there's no separate reset, just make sure the burner caps are seated flat and completely dry. If the oven igniter glowed for more than 90 seconds without the burner lighting, the board may have tripped a safety lockout that only clears with this full power cycle.

Frequently Asked Questions
Why does my igniter glow but the stove won't light?
This is the most common thing homeowners get confused about. The igniter and gas valve are wired in series. As the igniter ages, its resistance goes up and that drops the amperage it draws. The gas valve's solenoid needs to see at least 3.2 amps to physically pull open. If the igniter's only drawing 2.5 or 2.8, the valve stays shut even though the igniter looks hot and orange and totally normal. The fix is a new igniter, usually $30-$60 for the part.
Can I light my Whirlpool gas oven with a match?
Don't do it. These modern Whirlpool ovens use a safety valve that needs an electrical signal from a working igniter to stay open. Without that signal, gas doesn't flow, period. There's no pilot light to hold open manually. If someone tells you to shove a lit match in there and hit the Bake button, that's genuinely dangerous advice, because you're trying to force gas flow past a safety system that's specifically designed to prevent it. Get the igniter fixed.
How long do Whirlpool oven igniters typically last?
Honestly, 5-7 years with regular use is pretty typical. If you run the self-clean cycle a lot, that 900-degree heat is brutal on them and I've seen igniters fail in 3 years on ovens that get self-cleaned every month or two. Using the oven daily versus a few times a week makes a big difference too. When you replace one, go OEM if you can. The aftermarket ones are cheaper but they seem to weaken noticeably faster in my experience.
What does a clicking sound mean if the burner won't light?
Clicking is the spark module doing its job, sending rapid high-voltage pulses out to the electrode at the burner. If it's clicking but not lighting, you've usually got a clogged port, a burner cap that's not sitting flat on the burner head, or a cracked spark electrode. If it doesn't click at all, the spark module is probably dead or the switch inside the valve knob assembly is bad. Sometimes a knob switch gets so gummed up with grease it won't make contact when you turn it to Lite.
How much does it cost to fix a Whirlpool oven igniter yourself?
The igniter part itself runs about $25-$60 depending on whether you go OEM or aftermarket. Whirlpool part number WP816126 fits a ton of their models. Figure an hour of your time if you've never done it before. A service tech is going to charge you $150-$250 all in for parts and labor. It's honestly one of the more DIY-friendly repairs on a gas range. Just test the amperage on the new one after you install it, because I've seen new parts come out of the box already running weak.
