OEM Carrier Hot Surface Igniter for PY3PNA036090NA Furnace Unit

The hot surface igniter is what lights the burners on every heat call. When the gas valve opens, the igniter must glow white-hot to ignite the gas stream within seconds. When it cracks, ages, or fails, you'll get no heat at all: the inducer runs, you may hear the gas valve click, but the burners never light, the system locks out, and the furnace short-cycles trying again and again. Many failures show up as a furnace that runs the blower with cold air, or a control board flashing an ignition-failure or lockout fault code. This igniter is offered in the correct material and resistance for your unit. Legacy carbide igniters use brittle silicon carbide and typically read 40–75 ohms cold; modern replacements often use rugged silicon nitride, which resists thermal-shock cracking and the oil and dust contamination that kills carbide elements. Measure cold resistance with a meter — an open or out-of-range reading confirms a dead igniter. Why OEM matters: an igniter with the wrong resistance simply won't reach ignition temperature in the time the control board allows, causing repeated lockouts even on a brand-new part. Cheap universal igniters often use thinner elements and looser resistance specs, so they glow unevenly, burn out fast, or fail to light reliably on cold mornings. The correct OEM-spec igniter matches your board's timing and amperage exactly. Install difficulty: 2/5. Tools needed: 1/4" nut driver, a multimeter for resistance testing, and gloves. #1 safety warning: turn OFF the gas supply and kill power at the breaker before servicing — and NEVER touch the ceramic element with bare fingers; skin oils create hot spots that crack the igniter on its first cycle. Handle it only by the bracket. Ships same business day from our stocked warehouse on orders placed before 3 PM CST.
