OEM Carrier Hot Surface Igniter for PG8JAA024070AAJA Furnace

The hot surface igniter (HSI) is what lights the burners on your Carrier PG8JAA024070AAJA. On a call for heat the control board sends 120V to the igniter, which glows white-hot to ignite the gas as the valve opens. These elements are brittle and wear out from thermal cycling. When the igniter fails you get no heat with a furnace that goes through its inducer and pressure-switch sequence but never lights, or you hear the gas valve click open with no flame. A cracked or aged igniter may glow dimly, glow then crack on the next cycle, or not glow at all. This OEM igniter is the correct element for the PG8JAA chassis — most current Carrier units use a robust silicon nitride element rather than the older brittle silicon carbide design, giving longer life and faster, more reliable warm-up. A healthy igniter reads roughly 40–90 ohms cold across its terminals (silicon nitride runs higher than legacy carbide); an open or out-of-range reading means it's done. Why OEM matters: generic igniters often use thinner elements or off-spec resistance that won't reach ignition temperature reliably, causing failed lights and repeat lockouts, and they crack far sooner under thermal shock. The OEM silicon nitride element survives many more heat cycles. Install difficulty: 2/5. Tools: 1/4" nut driver, and a multimeter to confirm resistance before and after. Handle the new element ONLY by its ceramic base — skin oils on the hot surface create hot spots that crack it. #1 safety warning: TURN OFF the gas and kill the 120V breaker before reaching into the burner box; the igniter operates at line voltage.

Compatibility

This part is compatible with Carrier model PG8JAA024070AAJA. 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.
