OEM Carrier Hot Surface Igniter (LH33WZ008) for Model PY1PEA042100ADBA

This is the factory-specified OEM hot surface igniter (spark electrode ignitor) for the Carrier PY1PEA042100ADBA packaged unit. The igniter is the critical first step in every heating cycle — it heats to ignition temperature within seconds to light the burner assembly. When it fails, the control board will attempt ignition, detect no flame, and lock out the furnace, leaving you with a no-heat call. Typical symptoms include repeated ignition attempts with no flame, a blinking fault code, or the system cycling off after the trial-for-ignition period.

• OEM Part Number: LH33WZ008 | Factory-direct Carrier replacement | Exact fit, no modification required
• OEM vs Generic: This OEM igniter is manufactured to Carrier's exact temperature ramp-up rate and thermal cycling specs. Generic igniters often crack prematurely under thermal stress, reducing service life and risking repeat callbacks.
• Install Difficulty: 3/5 — Always shut off power and gas before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Handle igniter element with gloves only — skin oils cause hot spots and premature failure. Disconnect wiring harness, remove mounting screws, swap igniter, and reconnect.
• Warranty: 1-year OEM factory warranty. Orders placed by 3 PM ship same business day from our warehouse.
