OEM Carrier Hot Surface Igniter for Gas Furnace PY3PNA030040AB

The hot surface igniter is the ignition source for your Carrier gas furnace. On every call for heat, the integrated furnace control sends 120 volts to the igniter, which glows white-hot (around 2,000°F) and lights the gas streaming from the burners. It is one of the most failure-prone parts in any modern furnace because it is repeatedly heated and cooled. When it fails you'll typically get no heat even though the inducer and blower may run, a furnace that clicks and tries to fire but never lights, a visibly cracked or broken element, or a hard lockout after three or four failed ignition attempts — usually flagged by a flashing LED fault code at the control board. This is a silicon carbide hot surface igniter built to Carrier's original specification. Silicon carbide lights fast but is brittle, so handle it only by the ceramic base. A healthy igniter typically reads roughly 40–75 ohms cold across the terminals with a multimeter; an open (infinite) reading means a cracked element, and a reading far outside spec means it won't reach ignition temperature. The mounting bracket and 2-pin connector match the factory part for a true drop-in fit. OEM matters here: generic igniters are often wound to looser resistance tolerances or use thinner elements that draw the wrong current, so they either fail to glow hot enough for reliable ignition or burn out in a single season. A correct-resistance OEM element protects your control board and delivers full equipment life. Install difficulty: 2/5. Tools: 1/4" nut driver and a Phillips screwdriver. SAFETY: shut off the gas valve and kill power at the furnace switch/breaker before servicing, and never touch the element with bare fingers — skin oil creates hot spots that crack it early.

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.
