OEM Carrier Hot Surface Igniter for Gas Furnace PG8UAA024065ADJA

The hot surface igniter is the glow element that lights the burners on every heat call. When the thermostat calls for heat, the control board sends line voltage to the igniter, which glows white-hot and lights the gas the instant the valve opens. Igniters are brittle and fail from repeated thermal cycling — they crack, develop hairline fractures, or simply burn through. When that happens the furnace will run its inducer and blower but never light, so you get cold air or no air at all, often after an audible click with no "whoosh" of ignition. A furnace that locks out after three failed ignition attempts is the classic symptom of a dead igniter. Carrier furnaces in this family use a hot surface igniter, offered in legacy silicon carbide and modern silicon nitride. Silicon nitride elements are far more durable and resist the thermal-shock cracking that kills silicon carbide igniters. Cold resistance typically falls in the 40–75 ohm range for carbide elements and lower for nitride; the OEM part is matched to the board's voltage and current limits so it reaches ignition temperature within the trial-for-ignition window. A generic igniter with the wrong resistance won't glow hot enough — or fast enough — to light the gas inside the board's timed window, causing repeated lockouts even when the part is brand new. Under-spec elements also draw incorrect current and shorten relay life on the control board. OEM resistance and mounting geometry guarantee fast, reliable ignition and correct positioning in the flame path. Install difficulty: 2/5. Tools: 1/4" nut driver and possibly a Phillips screwdriver. Handle the element only by its ceramic base — skin oil weakens the glow surface. Safety: shut off the gas supply and disconnect power before servicing, and never touch the igniter element with bare fingers.

Compatibility

This part is compatible with Carrier model PG8UAA024065ADJA. Always verify the part number against your unit's data plate before ordering.

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.

Shipping & Returns

Same-day shipping on orders before 3 PM CST. Standard delivery 2-5 business days, express options available at checkout. 30-day hassle-free returns on uninstalled parts — free return shipping included. 1-year OEM factory warranty coverage.
