OEM Carrier Hot Surface Igniter for PG9MXA048080AASA Gas Furnace

The hot surface igniter lights the burners in your Carrier PG9MXA048080AASA gas furnace. On every call for heat the control board feeds this igniter 120V, and it glows white-hot (about 2,500°F) so the gas ignites instantly when the valve opens. Over time the element develops micro-fractures and rising resistance until it can no longer reach ignition temperature, and the furnace stops heating. Typical symptoms are clicking from the board, the blower delivering cold air, short-cycling, or several failed ignition attempts ending in a hard lockout and a diagnostic flash code. On a newer furnace, a failed igniter is the single most common no-heat cause. This is a genuine OEM silicon nitride hot surface igniter. Nitride elements withstand thermal shock and resist cracking far better than older silicon carbide, lasting thousands more on/off cycles. Rated for 120VAC, a healthy element reads in the tens to low hundreds of ohms cold (verify against the data plate); an open or infinite reading confirms a cracked element. The bracket and 2-pin connector match the factory harness for a genuine drop-in fit. With igniters, OEM matters. Generic universal units use cheaper elements with the wrong mass and resistance, so they heat slowly or unevenly and often fail to hold ignition temperature — producing delayed ignition, soft lockouts, and rollout. A correctly matched OEM nitride igniter glows hot enough, fast enough, every cycle, and lasts dramatically longer. Install difficulty: 2/5. Tools: 1/4-inch nut driver and a multimeter. SAFETY — shut off the gas and kill power at the breaker before servicing, and handle the igniter only by its ceramic base; never touch the brittle element, as skin oils and pressure create hot spots and cracks. Ships the same business day from our stocked U.S. warehouse on orders placed before 3 PM CST, backed by a 1-year OEM warranty. Returns are hassle-free for 30 days on uninstalled parts.

Compatibility

This part is compatible with Carrier model PG9MXA048080AASA. 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.
