Maytag Oven Igniter Issues: Signs and Replacement

If you’ve turned on your Maytag oven only to wait…and wait…and still no heat, you’re likely dealing with a faulty igniter. It’s one of the most common Maytag oven problems, and fortunately, one of the most straightforward to diagnose and fix. Let’s walk through the signs of a failing igniter and what you need to know about replacement.

What Does the Oven Igniter Actually Do?

Your Maytag gas oven’s igniter has two critical jobs. First, it draws electrical current to open the gas valve. Second, it creates the spark that ignites the gas flowing from the valve. When working properly, this entire process happens in about 90 seconds or less.

The igniter is a ceramic and metal component located at the back of the oven cavity, near the burner tube. Over time—typically after 3-5 years of regular use—the igniter weakens and can no longer perform both functions effectively.

Clear Signs Your Maytag Igniter Is Failing

The Oven Won’t Heat At All

This is the most obvious symptom. You set the temperature, hear the igniter clicking or see it glowing, but the oven never actually lights. The oven stays cold, and your dinner plans are ruined.

The Igniter Glows But Doesn’t Light

Here’s what happens with a weak igniter: it glows orange or even bright white, making it seem like it’s working fine. But if it glows for more than 90 seconds without lighting the gas, the igniter isn’t drawing enough current to open the gas valve fully. This is the classic sign of an igniter that’s on its way out.

Many homeowners in Grand Rapids call us thinking they have a gas valve problem when it’s actually just a weak igniter. The glow is deceiving—it looks functional but lacks the amperage needed to complete the ignition sequence.

Delayed Ignition With a “Whoosh”

If your oven eventually lights but only after 2-4 minutes, often with a small “whoosh” or puff of flame, that’s dangerous. What’s happening is gas is building up in the oven cavity before finally igniting all at once. This isn’t just inconvenient—it’s a safety hazard that needs immediate attention.

Intermittent Heating

Some days it works, some days it doesn’t. This unpredictability usually means the igniter is right on the edge of failure. Temperature and humidity can affect its performance just enough to make it unreliable.

Common Maytag Models With Igniter Issues

We see igniter failures across most Maytag gas ranges and wall ovens, but certain model series are particularly prone to this issue:

• Maytag MGR (gas range series)
• Maytag CWG (wall oven series)
• Gemini double oven models
• Maytag Centennial series

If you have a model number starting with these letters and you’re experiencing heating issues, the igniter is the first component to check.

Why Maytag Igniters Fail

Igniters fail because of normal wear and heat cycling. Every time you use your oven, the igniter heats to over 2000°F, then cools back down. This constant expansion and contraction gradually degrades the igniter’s ability to conduct electricity.

In West Michigan’s climate, where we go from humid summers to dry winters, the environmental changes can also contribute to faster igniter degradation—though this is a minor factor compared to simple usage over time.

Can You Test the Igniter Yourself?

Yes, with caution. Here’s a safe way to check:

1. Turn on your oven and watch the igniter (don’t touch it)
2. Time how long it glows before the gas lights
3. If it glows for 90+ seconds without lighting, it’s weak
4. If it doesn’t glow at all, it’s completely failed

You can also use a multimeter to test resistance. A good igniter should read between 40-400 ohms. Anything outside this range means replacement is needed. However, sometimes igniters test fine with a multimeter but still fail under load, so the timing test is often more reliable.

Replacement Parts and Costs

OEM (Original Equipment Manufacturer) Maytag igniters typically cost between $50-$90 for the part alone. The most common part numbers for Maytag ovens are:

• 74007498 (flat style igniter)
• WP74007498 (Whirlpool-branded equivalent)
• 12400035 (round style for older models)

Universal igniters are available for $25-$45, but we generally recommend sticking with OEM parts for reliability, especially in Maytag ovens. The slight cost savings isn’t worth a callback in a few months.

For professional installation, expect to pay $175-$275 total in the Grand Rapids area, including parts and labor. At HomeHalo, we keep common Maytag igniters in stock on our service vehicles, so we can usually complete the repair in a single visit.

DIY Replacement: Is It Worth It?

If you’re handy with tools and comfortable working around gas appliances, replacing an igniter is a manageable DIY project. The process typically takes 30-60 minutes and requires:

• Turning off the gas supply
• Unplugging the oven
• Removing the oven racks and bottom panel
• Disconnecting the wire harness
• Unbolting the old igniter
• Installing and securing the new one
• Reassembling everything
• Testing the repair

The biggest risks are damaging the ceramic igniter during installation (they’re fragile) or cross-threading the mounting bracket screws. If you’re not confident working around gas appliances, this is definitely a job for a professional.

When to Call a Professional

Call an appliance repair technician if:

• You’re not comfortable working with gas appliances
• The new igniter doesn’t solve the problem (could indicate gas valve or control board issues)
• You notice any gas odor at any point
• The igniter keeps failing repeatedly (underlying electrical issue)
• You have a double oven and aren’t sure which igniter is the problem

Sometimes what seems like an igniter issue is actually a failed gas valve, a faulty oven safety valve, or even a control board problem. An experienced technician can diagnose these issues quickly and prevent you from replacing parts unnecessarily.

Preventing Future Igniter Failure

While you can’t prevent igniters from eventually wearing out, you can maximize their lifespan:

• Avoid repeated short heating cycles (let the oven fully preheat)
• Keep the oven cavity clean to prevent buildup around the igniter
• Don’t use oven cleaners near the igniter area
• Consider an oven thermometer to avoid unnecessarily high temperature settings

Most Maytag igniters last 5-8 years with normal use, though we’ve seen them fail in as little as 2-3 years with heavy use (like in homes with large families) or last 10+ years in lightly-used ovens.
