OEM Carrier Hot Surface Igniter Replacement for PY3GNAA24040AA

The hot surface igniter glows red-hot to ignite the gas burners each time your Carrier PY3GNAA24040AA furnace calls for heat. Subjected to intense thermal stress on every cycle, it is the most frequently replaced part in a gas furnace. A failed igniter shows up as an inducer that runs and a gas valve that clicks, but burners that never light — meaning no heat, a furnace that locks out after several retry attempts, or flash codes signaling failed ignition. A cracked, blistered, or broken element is the tell-tale sign. Carrier OEM igniters are typically silicon nitride, which is far more durable than legacy silicon carbide and resists the micro-cracking caused by thermal cycling. Cold resistance usually measures in the 40–90 ohm range; verify with a multimeter — an open circuit (infinite resistance) confirms a dead igniter. It runs on 120 VAC. An igniter with incorrect resistance won't glow hot enough to reliably light the burners, producing delayed ignition, gas rollout, or no flame. Generic silicon carbide units are brittle, prone to cracking during install, and frequently mismatch the bracket or wiring connector. Choosing OEM ensures the correct resistance, glow temperature, and exact fitment for your furnace. Install difficulty: 2/5. Tools needed: 1/4" nut driver and a multimeter. #1 safety warning: shut OFF the gas supply and turn off power at the breaker before servicing. Do not touch the ceramic-and-element body with bare hands — finger oils create hot spots and shorten life; handle only by the base. Ships same business day from our stocked warehouse on orders before 3 PM CST. Includes a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.

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.
