OEM Carrier Hot Surface Igniter for PG8UAA024045ABJA Furnace

The hot surface igniter in your Carrier PG8UAA024045ABJA is the component that physically lights the burners. On a call for heat, the control board sends line voltage to the igniter, which glows white-hot before the gas valve opens and ignites the gas. A failed igniter is one of the most common no-heat causes: you'll hear the inducer spin and the gas valve click, but the burners never light, and the furnace locks out after three or four failed ignition attempts. Cracked or aged igniters often glow dimly, glow in spots, or crack invisibly so they read open on a meter. This genuine OEM igniter uses Carrier's specified element with the correct cold resistance (typically 40–75 ohms for the silicon carbide style used on this platform) and the matching bracket, gasket, and plug orientation. Confirm with a multimeter — an open or infinite reading confirms a dead element. Generic igniters often use mismatched resistance or thinner silicon carbide that doesn't reach full ignition temperature, causing delayed light-off, rough "boom" ignition, and dramatically shortened service life. The correct OEM element glows hot fast and seats with the proper air gap to the burner. Install difficulty: 2 of 5. Tools: 1/4" nut driver and a multimeter. SAFETY: turn off the gas supply and kill the furnace breaker before servicing. Handle the new igniter by its ceramic base only — skin oils from your fingers create hot spots that crack the element prematurely.
