If your gas oven turns on but won’t heat up, or takes forever to reach temperature, there’s a very good chance the problem is your igniter — specifically the 4342528 Whirlpool gas oven igniter.

This is one of the most common failures we see on Whirlpool, KitchenAid, Maytag, and Amana ovens.

Let’s break it down 👇


🔥 What Does the Oven Igniter Do?


The igniter is responsible for:

  • Opening the gas valve

  • Igniting the gas to create heat

When it works properly, you’ll see it glow bright orange before the burner lights.

⚠️ Signs Your 4342528 Igniter Is Bad

Here are the most common symptoms:

❌ Oven not heating at all

  • No flame inside the oven

  • Igniter may not glow

❌ Igniter glows but no flame

  • This is VERY common

  • Igniter is weak and not pulling enough amps

❌ Long preheat times

  • Temperature is inconsistent

👉 Even if it glows, it can still be bad.
