OEM Carrier Gas Furnace Hot Surface Igniter for PY3GNAA42060AA

The hot surface igniter (HSI) glows red-hot to light the gas at the burners on your Carrier PY3GNAA42060AA furnace. It is the most frequently replaced furnace part because the brittle element degrades a little with every heating cycle. When it fails you get no heat: the inducer runs, you hear the gas valve attempt to open, but the burners never light, usually followed by a lockout and a flashing fault code. A visibly cracked element, a white or blistered surface, or one that no longer glows is the giveaway. Confirm whether your furnace uses a silicon carbide element (the classic brittle gray igniter, roughly 40 to 75 ohms cold resistance, 120V) or the newer, more durable silicon nitride element. Check resistance with a multimeter: an open (OL/infinite) reading means a dead igniter. Match the mounting bracket and the plug/connector style to your original, Carrier PY3 furnaces use a specific bracket orientation so the element sits correctly in the burner flame path. Igniters live or die on resistance and element quality. A generic igniter with the wrong resistance will not reach the temperature needed to ignite gas reliably, causing hard starts, delayed-ignition "puff" lightoffs, or repeated lockouts that crack the heat exchanger over time. OEM Carrier igniters use correctly spec'd elements and brackets so the glow temperature and flame position are right. Install difficulty: 2/5. Tools: 1/4" nut driver and a multimeter. SAFETY: turn off the gas and the power first. Remove the single mounting screw, unplug the connector, and handle the new igniter only by its ceramic base, never the element, skin oil creates hot spots that crack it.
