OEM Carrier Silicon Nitride Hot Surface Igniter for PY4GNAB42060AA

The hot surface igniter is the ignition source for your Carrier gas furnace. On every call for heat the control board energizes the igniter, which glows to roughly 2,000°F and lights the burner gas. When it fails you'll notice the blower running but pushing cold air, the furnace clicking and trying to fire then locking out after three attempts, a delayed ignition "poof," or no heat at all on the coldest nights. A cracked or worn element is the single most common cause of a no-heat service call. This is a silicon nitride hot surface igniter, far more durable than older silicon carbide elements that crack from thermal shock and handling. Cold resistance typically reads in the 40–75 ohm range; an open circuit (OL on your meter) confirms a failed element. It is built for 120 VAC line-voltage ignition systems. Igniter resistance is matched to your control board's current limits. A generic igniter with the wrong resistance either won't glow hot enough to reliably light gas — causing rough, delayed ignition — or draws excess current that shortens the board's relay life. OEM silicon nitride elements also resist the micro-cracking that ends most generic igniters within a single heating season. Install difficulty: 2/5. Tools: 1/4" nut driver and a multimeter; allow about 20 minutes. #1 safety warning: turn off the gas supply and kill power at the furnace breaker before servicing, and never touch the element with bare fingers — skin oils create hot spots that crack the ceramic.

Compatibility

This part is compatible with Carrier model PY4GNAB42060AA. 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.
