OEM Carrier Spark Electrode Igniter LH33WZ008 for Model PY1PPA048100AGBA

This is the factory-specified OEM spark electrode igniter for the Carrier PY1PPA048100AGBA packaged unit. The igniter is the first component in the gas heating sequence — after the draft inducer proves airflow, the igniter receives voltage, heats to ignition temperature, and ignites the main burners as the gas valve opens. When this part fails, the furnace completes its ignition attempt but never lights, triggering a system lockout after 3 failed cycles. You may notice the unit blowing cold air, a hard lockout fault on the control board, or a visibly cracked or broken electrode element upon inspection.

• Part Number: LH33WZ008 | OEM Carrier Spark Electrode Igniter | Genuine Carrier factory part — no substitutions or tolerance mismatches
• OEM vs Generic: OEM igniters are manufactured to exact factory gap spacing and material specifications. Aftermarket electrodes can have incorrect tip geometry or inferior materials, leading to misfires, premature cracking, and repeat service calls.
• Install Difficulty: 3/5 — Shut off gas and power before beginning. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify 120V supply and electrode continuity). Handle the electrode tip with care — never touch the ceramic insulator with bare hands, as skin oils cause premature failure. Photograph wiring before disconnecting.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
