If your heater isn’t starting up or you notice it’s blowing cold air, the igniter could be the issue. Common signs include:

• No glow or spark: The igniter doesn’t light up when the heater tries to start.
• Repeated clicking: You hear clicking but the heater doesn’t ignite.
• Burn marks or cracks: Visible damage on the igniter itself.
• Heater cycling: The unit turns on and off without heating.

For safety, always turn off power and gas before inspecting. If you’re unsure, it’s a good idea to contact a professional for diagnosis.

A heater igniter is a small but essential part that helps start your gas or electric heater. Its main job is to create the spark or heat needed to ignite the fuel, which then warms the air in your home. There are different types, like hot surface igniters and spark igniters, but they all serve the same purpose—making sure your heater fires up safely and efficiently. Without a working igniter, your heater won’t be able to produce heat, even if everything else is working fine.

Some people with basic DIY skills can replace a heater igniter, but it’s important to follow safety steps. Here’s what you should know:

• Turn off power and gas: Always shut off the heater before starting.
• Check your manual: Find the right replacement part for your model.
• Handle with care: Igniters are fragile and can break easily.

If you’re not comfortable working with electrical or gas components, it’s best to call a qualified technician. This helps avoid damage or safety risks.

To pick the right igniter, you’ll want to:

• Check your heater’s model number: This info is usually on a label inside the unit.
• Match specifications: Look for voltage, size, and connector type that fit your heater.
• Review compatibility: Some igniters are universal, but many are specific to certain brands or models.

If you’re unsure, bring your old igniter or details to the store, or check the product descriptions online for compatibility information. This helps ensure a proper fit and safe operation.

You can find a wide selection of heater igniters at Walmart, both in-store and online. Just search for your heater’s model or browse the heater igniter section to see compatible options. Product listings often include details about which models they fit, so you can double-check before buying. If you need help, Walmart associates are available to answer questions or help you find the right part for your heater.
