OEM Carrier Silicon Nitride Hot Surface Igniter for PG8MAA066135ABJA

The hot surface igniter is the component that lights the gas at the burners every time your Carrier PG8MAA furnace calls for heat. When it fails, the most common symptom is no heat: the furnace runs its startup sequence — the inducer spins up and you hear the gas valve click — but the burners never light, and the control board locks the unit out after three or four failed tries. A cracked or aging igniter can also glow weakly or unevenly, producing delayed ignition and a small 'whoomp' as gas pools before catching. Homeowners often notice short-cycling on the coldest nights, exactly when the igniter is on its last legs. This is a silicon nitride hot surface igniter, the modern and far more durable successor to older silicon carbide elements. Silicon nitride resists the thermal shock and brittle cracking that kill carbide igniters, so it typically lasts much longer. Cold resistance generally reads in the 40–75 ohm range on a multimeter; an open reading (OL) means the element is cracked and must be replaced. It operates on 120VAC. With igniters, OEM matters because the element geometry and resistance are matched to your board's ignition warm-up timing. A generic igniter with the wrong resistance won't reach the correct surface temperature in the board's allotted window, so it won't glow hot enough to reliably light gas — causing nuisance lockouts. Bargain aftermarket carbide elements are also far more fragile. Install difficulty: 2/5. Tools: 1/4" nut driver and gloves. #1 safety warning: turn off the gas and kill power at the furnace switch before servicing, and never touch the element with bare fingers — skin oils create hot spots that crack it.

This part is compatible with Carrier model PG8MAA066135ABJA. 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.
