Oven Igniter Failure – What It Looks Like and How to Fix It

If your gas oven won’t light or takes forever to heat up, the igniter is probably the culprit. Most homeowners think the problem is the burner or the gas line, but a weak or cracked igniter will do the same thing. The good news? You can often test and replace it yourself, saving time and money. Below we break down the signs, the simple checks, and the exact steps to get your oven cooking again.

How to Tell Your Oven Igniter Is Bad

First, listen for the familiar click when you turn the oven on. A healthy igniter glows bright orange for a few seconds before the flame lights. If you hear the click but see no glow, the igniter is dead. A dim or flickering glow means it’s wearing out – it still works but can’t sustain the heat needed for reliable ignition.

Other clues include a lingering smell of gas, an oven that heats unevenly, or error codes on the display (many modern ovens show an “IGN” code). If you’ve tried cleaning the burner and the problem persists, skip straight to the igniter test.

To test, unplug the oven or turn off the circuit breaker, then locate the igniter – it’s usually a small metal rod near the burner. Use a multimeter set to 200 Ω. A healthy igniter reads between 70 and 120 Ω. Anything higher means it’s broken and needs replacing.

Fix or Replace: Step‑by‑Step Guide

Once you know the igniter is bad, decide if you’ll replace it yourself. If you’re comfortable working around gas components and have basic tools, the DIY route is straightforward and can cost as little as ₹1,500–₹3,000 for a new part.

Step 1 – Gather tools. You’ll need a screwdriver set, a multimeter (already used), and the correct replacement igniter model for your oven (check the brand and part number).

Step 2 – Remove the old igniter. With the oven unplugged, unscrew the burner assembly, then pull the igniter out of its socket. Some models have a clip; just release it gently.

Step 3 – Install the new igniter. Align the pins, push it into the socket, and secure any clips. Re‑attach the burner and screw everything back.

Step 4 – Test the oven. Turn the power back on, set the oven to bake, and watch for that bright orange glow followed by the flame. If it lights consistently, you’re good to go.

If the new igniter doesn’t work, double‑check the gas supply and the oven’s control board. Sometimes a control board fault can mimic an igniter issue. In that case, or if you’re uneasy about handling gas parts, call a professional. A qualified tech can diagnose control board problems and ensure everything meets safety standards.

Keep in mind that repeated igniter failures often point to deeper issues like poor ventilation around the oven or a clogged burner. Give the area a good clean, and consider scheduling a routine service if the oven is older than 7‑8 years.
