OEM Carrier Silicon Carbide Hot Surface Igniter for PG8UAA048091ADJA

The hot surface igniter is the first component to fire in your Carrier PG8UAA048091ADJA gas-electric package unit. On a call for heat, the control board sends 120V to the igniter, which glows white-hot to ignite the gas at the burners. When it fails, you'll notice the inducer running and the board clicking but no flame, cold air from the registers, or the unit locking out after three failed ignition attempts — a classic short-cycling, no-heat symptom. A cracked or aged igniter is the single most common reason a Carrier package unit stops heating. This is a silicon carbide hot surface igniter rated for 120VAC. Cold resistance typically falls in the 40–75 ohm range; an open-circuit (infinite ohm) reading on your multimeter confirms a failed element. The ceramic mounting block and gasket are matched to the Carrier burner assembly so the igniter sits at the correct depth and angle for reliable flame carryover. OEM matters here because silicon carbide igniters are fragile and dimensionally precise. Generic universal igniters often use thinner elements or incorrect mounting depths, so they glow unevenly, crack within a season, or sit too far from the gas stream to light reliably. The genuine Carrier part is matched to your burner's ignition timing. Install difficulty: 2 of 5. Tools needed: 1/4" nut driver and a multimeter for verification. SAFETY: turn off the gas at the shutoff valve and kill power at the breaker before servicing. Never touch the silicon carbide element with bare fingers — skin oils create hot spots that crack the ceramic. Ships same business day from our stocked warehouse on orders placed before 3 PM CST. Backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.
