OEM Carrier Furnace Hot Surface Igniter for PG8UAA066111ADJA

The hot surface igniter is the component that lights the gas burners in your Carrier PG8UAA066111ADJA furnace. On every call for heat, the control board sends voltage to the igniter, which glows white-hot and ignites the gas. When it fails, the most common symptom is no heat: the furnace runs its sequence — the inducer spins up, you hear the gas valve click — but the burners never light, and the unit locks out after three failed tries. A bad igniter often shows a visible crack or hairline fracture, and sometimes it still glows but not hot enough to light the gas. You may also notice short-cycling or the blower pushing cold air. Specs: This is a silicon nitride igniter, which is far more durable than the older brittle silicon carbide elements that crack easily. Cold resistance typically reads 11–18 ohms on a multimeter; an open (infinite) reading confirms a failed element. It runs on 120V line voltage and is a direct fit for the PG8UAA furnace line. Why OEM matters: Igniter resistance and material are everything here. Generic igniters often use cheaper silicon carbide with resistance values outside spec, so they either draw too much current and burn out fast, or never reach ignition temperature, leaving you with intermittent no-heat lockouts. A genuine OEM silicon nitride element matches the furnace's ignition timing and survives far more on/off cycles. Installation difficulty: 2/5. Tools needed: 1/4" nut driver and a multimeter. #1 safety warning: TURN OFF the gas supply and kill power at the breaker before servicing. Handle the new igniter only by its ceramic base — skin oils create hot spots that crack the element. Ships same business day from our stocked warehouse on orders placed before 3 PM CST.

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.
