OEM Carrier Silicon Nitride Hot Surface Igniter for PY1PEA042080ACBA

The hot surface igniter is the part that lights the burners on your Carrier PY1PEA042080ACBA. When the thermostat calls for heat and the pressure switch proves draft, the control board sends line voltage to the igniter, which glows white-hot and ignites the gas as the valve opens. Igniters are the single most common gas-furnace failure: they're brittle and degrade with every heating cycle. When one cracks or weakens you get no heat at all — the inducer runs, you may hear gas valve clicks, but the burners never light, and the board eventually locks out after several failed attempts. A telltale sign is an igniter that glows dull orange or not at all instead of bright white. This OEM igniter is a silicon nitride element — far more durable and thermal-shock resistant than older silicon carbide "glow bars" — with a cold resistance typically in the 40-75 ohm range and a mounting bracket and connector keyed for the PY1PEA042 burner assembly. OEM matters because the igniter's resistance and surface area are engineered to reach ignition temperature in the board's allotted timing window. A generic igniter with the wrong resistance may not glow hot enough to light reliably, or draws excess current and burns out prematurely — leaving you with repeat no-heat calls every season. Install difficulty: 2/5. Tools: 1/4" nut driver, a short Phillips screwdriver, and a multimeter to verify resistance. #1 safety warning: turn OFF the gas and power at the breaker first, and NEVER touch the igniter element with bare fingers — skin oil creates hot spots that crack it.
