OEM Carrier LH33ZS003 Hot Surface Igniter for PG8MAA036070ADJA

The hot surface igniter is what lights the burners on your Carrier PG8MAA036070ADJA. On each call for heat the control board sends 120V to the igniter, it glows white-hot, and the gas valve opens onto that glowing element to start combustion. Igniters are the single most common furnace failure because the element is brittle and degrades every time it heats and cools. When it cracks, you get the full startup sequence — inducer spins, you hear the click of the gas valve — but no flame, no heat, and a furnace that locks out after a few tries. Often the igniter glows dimly or not at all, or it shatters with a faint tick on a cold morning. This is a genuine Carrier silicon-carbide hot surface igniter (LH33ZS003 family) with the correct bracket, gasket, and connector for a true plug-in fit. Cold resistance reads roughly 40–90 ohms on a good unit; an open reading or wildly high resistance confirms a cracked element. Why OEM matters: silicon-carbide elements are fragile and tolerance-sensitive. Generic igniters often draw the wrong current and either fail to reach ignition temperature (no light-off) or run hotter than spec and burn out in a single season. The genuine Carrier igniter matches the original resistance and element mass the board was tuned for. Install difficulty: 2/5. Tools: 1/4" nut driver, a multimeter to check resistance, and clean gloves — never touch the element with bare fingers, as skin oils create hot spots that crack it. #1 safety warning: cut power at the breaker first, and let the igniter cool; it reaches over 2000°F in operation.
