OEM Carrier Silicon Nitride Hot Surface Igniter for PG8JAA024070AEJA

The hot surface igniter lights the burners on your Carrier PG8JAA024070AEJA packaged gas unit. Every time the thermostat calls for heat, the control board energizes the igniter, driving its tip to about 2,000°F to ignite gas at the burner manifold. It is the most frequently replaced part in any gas furnace. When the igniter cracks or its resistance drifts, the furnace can't light: the inducer spins up, you hear the gas valve click, but the burners stay dark, the system locks out after several retries, and your registers blow cold air. An igniter that glows but fails to ignite, or one that no longer glows at all, both signal it's time to replace. This is a silicon nitride element, engineered to outlast the fragile silicon carbide igniters found in older furnaces. Silicon nitride shrugs off thermal shock and oxidation, surviving thousands more on-off cycles. Expect a cold resistance in the 40–75 ohm range; an open reading or values well outside that window confirm a failed igniter. With igniters, OEM means the correct resistance and heat-up curve for this control board. An igniter with the wrong resistance either never reaches ignition temperature — leaving you with cold-weather lockouts — or overdraws current and burns out prematurely. Bargain generic igniters use lower-grade elements and loose tolerances that simply don't glow hot enough when it counts. Install difficulty: 2/5. Tools needed: 1/4" nut driver and a multimeter to check resistance. Never handle the ceramic tip with bare fingers — skin oils create hot spots that crack it. #1 safety warning: turn off the gas supply and shut off the breaker before servicing. Ships same business day from our stocked warehouse on orders placed before 3 PM CST. Backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.

Compatibility

This part is compatible with Carrier model PG8JAA024070AEJA. Always verify the part number against your unit's data plate before ordering.

Why Choose OEM?

OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.

Shipping & Returns

Same-day shipping on orders before 3 PM CST. Standard delivery 2-5 business days, express options available at checkout. 30-day hassle-free returns on uninstalled parts — free return shipping included. 1-year OEM factory warranty coverage.
