Nordyne Furnace Igniter Parts

Nordyne Furnace Igniter Parts

The hot surface igniter is the hardest-working part in your Nordyne furnace. When it glows orange and opens the gas valve, your heating cycle begins — and when it fails, nothing happens. Nordyne furnaces (including Intertherm, Miller, and Gibson brands) rely on a ceramic igniter that heats to over 1800°F in seconds. If your furnace clicks but won't ignite, or you see an orange glow that fades before gas flows, the igniter has likely weakened or cracked.

Nordyne igniters come in two types: silicon carbide (SiC) and silicon nitride (SiN). Your model number determines which one fits — using the wrong type means the furnace won't start, even though the part looks identical. Order the correct igniter, verify the ohm rating matches your original, and your heating should come back on within minutes.

• Igniter glows orange but goes out before gas flows: ceramic element is weak; replace it
• Igniter doesn't glow at all: cracked element or open circuit; OEM igniter required
• Furnace clicks rapidly then stops: weak igniter trips the safety lockout; igniter replacement fixes it
• Igniter glows but is dim or dull red: element aging; replacement will restore bright orange glow and faster ignition
• Igniter sparks or pops: ceramic fracture; replace immediately to prevent secondary damage

Nordyne Furnace Igniter: Frequently Asked Questions

How do I know if my Nordyne furnace igniter has failed?

A failing Nordyne igniter usually shows itself in one of two ways: either it glows but the furnace doesn't light (gas valve won't open because igniter is too weak), or it doesn't glow at all (element is cracked or the circuit is open). You may also hear the furnace clicking repeatedly as the control board detects no flame and shuts down the ignition cycle. If you see any orange glow at all, the igniter is in its final hours — replace it before it goes completely dead.

What's the difference between SiC and SiN igniters for Nordyne furnaces?

Silicon carbide (SiC) and silicon nitride (SiN) igniters are NOT interchangeable, even though they look similar. Your Nordyne model number determines which type your furnace requires. SiC igniters are older and more common in Intertherm and Miller furnaces; SiN igniters are found in newer, higher-efficiency Nordyne models. Using the wrong type will result in a furnace that won't ignite, so always verify your model number before ordering. Repair Clinic's model lookup will confirm the correct igniter type and part number for you.

Can I clean my Nordyne igniter instead of replacing it?

Unlike flame sensors (which can be cleaned with fine steel wool), hot surface igniters cannot be safely cleaned. The ceramic element is fragile, and any attempt to scrub or brush it will crack it. If your igniter is visibly dirty, a cracked element is often already present underneath the dust. Always replace rather than clean — an OEM Nordyne igniter is a $30 to $60 part that will give you 5 to 10 years of reliable starts.

My Nordyne furnace is from the 1990s — can I still get the right igniter?

Yes. Repair Clinic carries Nordyne and Intertherm igniter parts for models from the 1980s forward. Enter your complete model number on the product page, and the system will confirm availability and show you the exact igniter (including SiC vs. SiN type) that fits your furnace. Older Nordyne/Intertherm models often use SiC igniters, which are still in production.

Nordyne Furnace Model Number: Where to Look

On Nordyne furnaces, look for the model number on the blower compartment door or the data plate inside the front access panel. You may also find it near the gas valve, depending on the furnace design. Record the complete model number, including letters and numbers, before searching for parts. Enter it in the model number search to pull up the parts matched to your unit, not just one part or part category. Using the full furnace model helps narrow Repair Clinic's catalog to compatible parts for the entire unit. That means fewer wrong orders and a faster repair.
