OEM Carrier Hot Surface Igniter Assembly (50HJ403022) for Model PY1RJA036074ABWB

This is the factory-specified OEM igniter assembly for the Carrier PY1RJA036074ABWB packaged gas/electric unit. The hot surface igniter is the first component activated in every heating cycle — it glows to ignition temperature to light the burners safely and reliably. When this part fails, the furnace will attempt ignition, come up empty, and enter a lockout fault, leaving you with no heat. Common symptoms include the system running through 3 ignition attempts and locking out, the inducer running but no flame establishing, or fault codes indicating an ignition failure on your thermostat or control board.

• Part Number & Specs: OEM Part# 50HJ403022 (replaces legacy part 48VL400002) | Ceramic body construction | Approx. 4.25″ L × 2.95″ W × 1.75″ H | ~0.095 lb | Complete assembly includes igniter element and factory mounting bracket
• OEM vs Generic: This is a genuine Carrier OEM igniter, manufactured to exact factory specifications for your PY1RJA036074ABWB unit. Generic igniters are often made from lower-grade silicon carbide and may crack prematurely under thermal cycling. OEM ceramic construction resists thermal stress for longer service life and preserves your equipment warranty.
• Install Difficulty: 2/5 — Straightforward swap for a qualified technician. Always disconnect power at the disconnect and allow the igniter to cool completely before handling. Never touch the ceramic element with bare hands — skin oils cause hot spots and premature failure. Tools needed: 1/4″ nut driver, needle-nose pliers. Reuse the existing wire harness connector.
• Warranty & Shipping: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse when ordered before cutoff.
