OEM Carrier Hot Surface Igniter for PG8JAA024045ADJA Furnace

The hot surface igniter lights the burners on your Carrier PG8JAA024045ADJA gas furnace. On every call for heat, the control board energizes the igniter, which glows red-hot to ignite the gas streaming from the burners. When it fails, the classic symptom is no heat: the inducer spins, you hear the gas valve click, but the burners never light — and after three retries the board locks out the furnace. Homeowners typically notice short-cycling, a unit that "tries" then quits, cold air from the registers, or a faint glow that never reaches full brightness. A hairline crack in the element is often invisible but enough to kill ignition. This is a genuine Carrier silicon carbide hot surface igniter rated for 120VAC. A healthy igniter reads roughly 40–75 ohms cold across its terminals; an open (infinite/OL) reading confirms a burned-out element. The ceramic base and original wire harness/connector are matched to the PG8JAA furnace so it seats correctly and reaches ignition temperature within the board's trial-for-ignition window. Why OEM matters here: silicon carbide igniters are brittle and tolerance-sensitive. Generic aftermarket elements often have inconsistent resistance, thinner carbide, or weaker mounting tabs — they may glow but not hot enough for reliable light-off, or crack within a season from thermal cycling. The genuine part holds Carrier's resistance spec and survives more ignition cycles. Install difficulty: 2/5. Tools: 1/4" nut driver, multimeter. #1 safety warning: shut off the furnace at the breaker AND close the gas supply before servicing. Handle the new igniter by its ceramic base only — skin oil on the element shortens its life. Ships same business day from our stocked warehouse on orders placed before 3 PM CST.
