OEM Carrier Furnace Hot Surface Igniter for PG8MAA024070AAJA

The hot surface igniter (HSI) is what lights the burners on your Carrier PG8MAA024070AAJA. When the thermostat calls for heat and the pressure switch proves, the control board sends voltage to the igniter, which glows white-hot to ignite the gas. Igniters are brittle and are the most frequently replaced furnace part. When one fails you'll get no heat with the inducer running but burners that never light — sometimes a faint click of the gas valve but no flame, then a board lockout after 3–4 tries. A visibly cracked or no-longer-glowing element, or one that lights weakly and inconsistently, are the telltale signs. This OEM igniter is matched to the PG8MAA's ignition circuit. Many Carrier furnaces of this generation use a rugged silicon nitride element rather than the fragile silicon carbide 'M-series' style — silicon nitride resists thermal shock and lasts far longer. Cold resistance typically falls in the 40–75 ohm range; an open or out-of-spec reading confirms a dead igniter. Why OEM matters: aftermarket igniters often ship with the wrong resistance or a mismatched element material. Too high a resistance and it won't reach ignition temperature — you get delayed ignition or a 'whoomp' rollout; too fragile and it cracks within a season. The OEM unit's resistance and material are specified for this board's voltage and timing. Install difficulty: 2/5. Tools: 1/4" nut driver, Phillips screwdriver, multimeter for the resistance check. Handle the element by the ceramic base only — skin oils cause hot spots. #1 safety warning: TURN OFF GAS and power before servicing; the element reaches 1,800–2,500°F. 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.

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.
