Jump To Section

Silicon Carbide (SiC)

Traditional flat-element ignitors. 40-90 ohm range. Reaches ignition in 17 seconds. Found in most furnaces manufactured before 2010. Fragile — handle with care.

Silicon Nitride (Si3N4)

Modern upgrade material. 8-360 ohm range. More durable with 7-10+ year lifespan. Recommended replacement for all silicon carbide ignitors. Won’t crack as easily.

Universal vs. Direct Fit

Universal ignitors (like the Robertshaw 41-803N) include mounting brackets to fit 150+ models. Direct-fit ignitors match exact OEM connector and mounting without adapters.

Important: Always verify voltage (120V vs. 80V vs. 95V), connector type, and lead wire length before purchasing a replacement ignitor. When in doubt, bring the old ignitor to your local parts counter for a visual match.

Ignitor Types Explained

Silicon Carbide (SiC) — The Traditional Choice

Silicon carbide ignitors are the original hot surface ignitor technology used in residential furnaces since the 1980s. They have a characteristic flat, gray ceramic element that glows orange when energized. SiC ignitors are fragile and can crack from physical contact, oil from bare hands, or thermal cycling over time. They typically operate at 40-90 ohms and reach ignition temperature in about 17 seconds. Average lifespan is 3-5 years depending on cycling frequency.

Silicon Nitride (Si3N4) — The Modern Upgrade

Silicon nitride ignitors are the newer, more durable replacement technology. They can be either flat or round elements and are significantly more resistant to cracking, thermal shock, and physical damage. Si3N4 ignitors heat up faster (as quick as 3 seconds for some models), last 7-10+ years, and are generally recommended as upgrades when replacing failed silicon carbide ignitors. Most universal replacement kits on the market today are silicon nitride.

Pro Tip: If you’re replacing a failed silicon carbide ignitor, consider upgrading to a silicon nitride universal like the Robertshaw 41-803N or Honeywell Q3200U1004. They cost slightly more upfront but last 2-3x longer and are far less likely to crack during installation.

Frequently Asked Questions

Can I replace a silicon carbide ignitor with silicon nitride?
Yes, in most cases. Silicon nitride is an upgrade and is backward-compatible with silicon carbide applications. Just make sure the voltage, connector type, and lead wire length match your furnace. Universal kits include adapters to handle most mounting differences.
My ignitor glows but the furnace won’t light. Is it bad?
Not necessarily. If the ignitor glows bright orange, it may still be working. The issue could be a weak ignitor that isn’t reaching full temperature (check ohm readings — too high means it’s weakening), a gas valve issue, or a cracked heat exchanger causing a safety lockout. Measure the ignitor’s resistance with a multimeter — if it’s significantly above the rated range, replace it.
How do I know which ignitor I need?
The easiest method is to find the part number stamped on your existing ignitor or printed on a label near the burner assembly. Search that number in our OEM Lookup table above. Alternatively, find your furnace model number (usually on a label inside the blower compartment) and check the manufacturer’s parts list.
What’s the difference between the 41-802N and 41-803N?
Both are universal silicon nitride replacements, but the 41-802N has a 2.5″ lead wire (flat element) while the 41-803N has a 15.5″ lead wire (round element with universal brackets). The 41-803N replaces more models because of its longer leads and included mounting hardware. It’s the most versatile universal ignitor on the market.
Do I need to turn off gas before replacing an ignitor?
Yes, always. Turn off the furnace at the thermostat, shut off the gas supply, and disconnect power at the breaker before removing the old ignitor. Never handle a new silicon carbide ignitor with bare hands — oils from your skin can cause hot spots that lead to premature failure.
Can I use a MARS 67900 universal kit to replace any ignitor?
The MARS 67900 is a silicon carbide universal kit that covers many common models, but not all. Check the “67900 Compatible” column in the MARS cross-reference — some OEM ignitors (marked “NO”) require a specific replacement due to connector type or mounting differences.
