OEM Carrier Gas Furnace Hot Surface Igniter for PY3GEAA36090NA

The hot surface igniter is the ignition source for your Carrier gas furnace. On every call for heat, the control board sends voltage to the igniter and it glows red-hot (1,800–2,500°F) to ignite the gas at the burners. When it fails, the inducer and blower may run while the unit makes no heat, you'll often hear repeated clicking as the board retries ignition, and the furnace will lock out after three or four failed attempts — leaving you with cold air from the registers on the coldest nights. A cracked or worn igniter is among the most common no-heat service calls. Specifications: This OEM element is built from silicon nitride, which is far more durable and shock-resistant than the older silicon carbide igniters that crack from thermal cycling. Cold resistance typically reads 40–75 ohms on a multimeter; an open (infinite) reading confirms a failed element. Rated for 120V line-voltage operation, it matches the original mounting bracket and connector for a true drop-in fit. Why OEM matters: Igniter resistance is critical. A generic element with the wrong resistance won't reach the temperature needed to reliably light the burners, causing intermittent ignition and nuisance lockouts — or it runs too hot and burns out within a single season. OEM silicon nitride holds tight tolerances and survives thousands of ignition cycles where cheaper aftermarket carbide replacements fail in months. Installation: Difficulty 2 of 5. Tools needed: 1/4" nut driver and a multimeter. SAFETY: shut off the gas at the valve and kill power at the furnace switch or breaker before servicing. Never touch the ceramic element with bare fingers — skin oils create hot spots that drastically shorten its life. Ships same business day from our stocked warehouse on orders placed before 3 PM CST.

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.
