OEM Carrier Gas Furnace Hot Surface Igniter for PG9MAA024040AFKA

The hot surface igniter glows red-hot to light the gas at the burners on every call for heat. When it fails, you get no heat: you'll hear the inducer spin up and the gas valve click, but never the gentle "whoomph" of ignition. The furnace typically retries two or three times, then drops into a hard lockout. A bad igniter often shows a visible crack or simply never glows, and brittle older elements snap from thermal cycling. Specs: The PG9MAA uses a 120V silicon nitride hot surface igniter — tougher and far less brittle than the older silicon carbide "M-series" style — designed to survive thousands of ignition cycles. Cold resistance reads roughly 40–75 ohms across the two terminals on a multimeter; an open (infinite) reading means the element is cracked and dead. It mounts to the PG9MAA burner bracket with the correct tip position in the gas stream. Why OEM: An igniter's resistance determines how hot it gets and how quickly. A generic igniter with the wrong resistance may not reach ignition temperature inside the board's timed trial-for-ignition window — causing lockouts — or it may run too hot and burn out early. OEM silicon nitride matches the furnace's warm-up timing and outlasts cheap aftermarket carbide elements. Install difficulty: 2/5. Tools: 1/4" nut driver and a multimeter to confirm resistance. Handle the new igniter only by its ceramic base — skin oils create hot spots that weaken the element. #1 safety warning: turn off the gas at the shutoff valve and kill the breaker before servicing.
