OEM Carrier Hot Surface Igniter (Spark Electrode) for Model PY3GEAA48090AA — Part# 48VL400002

This is the genuine OEM replacement hot surface igniter for the Carrier PY3GEAA48090AA packaged gas/electric unit. The igniter — also described by Carrier as a Spark Electrode Ignitor — is responsible for lighting the burner during each heating cycle. When this component fails, the control board will attempt ignition, find no flame signal, and lock out the furnace section, resulting in a no-heat call with a hard lockout fault code. Common symptoms include: the inducer starts but the burners never fire, repeated ignition attempts followed by lockout, or a visibly cracked/broken igniter element found during inspection.

• Part Specs: OEM Part# 48VL400002 | Factory spark electrode ignitor | Engineered to factory voltage draw and element geometry for the PY3GEAA48090AA burner assembly
• OEM vs Generic: This is a genuine Carrier OEM igniter — not an aftermarket approximation. OEM igniters are matched to the exact element resistance, mounting bracket dimensions, and connector type of your unit, reducing the risk of premature cracking or nuisance lockouts common with off-brand alternatives.
• Install Difficulty: 3/5 — Shut off gas supply and 120V power before beginning. Tools needed: 1/4" and 5/16" nut drivers, a multimeter (to verify element resistance ~40–90 Ω), and needle-nose pliers. Do not handle the igniter element with bare hands — skin oils accelerate element failure. Use gloves or the original packaging to hold the element during installation.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
