OEM Carrier Flame Sensor Assembly LH33WZ005 for Model PY1PEA036120ACBA

This is the genuine OEM Carrier flame sensor assembly (part# LH33WZ005), factory-specified for the Carrier PY1PEA036120ACBA packaged heat pump unit. The flame sensor — also called a flame rod — generates a small microamp current when it detects a burner flame, signaling the control board that safe combustion is established. When the sensor fails or becomes coated with oxidation, the control board cannot confirm ignition and will shut the gas valve within 5–8 seconds, triggering a lockout fault. The result: your system attempts to fire, briefly lights, then shuts off and repeats — or goes straight to lockout with no heat.

• Specs: Flame rod sensor assembly | 64-1/2" wire lead | Factory Authorized Part (FAP) | OEM part# LH33WZ005 | For Carrier PY1PEA036120ACBA
• OEM vs Generic: This OEM assembly is built to Carrier's exact rod geometry, coating, and connector spec. Generic sensors often have incorrect rod length or angle, producing inconsistent microamp readings that cause nuisance lockouts even after installation.
• Install difficulty: 2/5 — Turn off power and gas before beginning. Tools needed: 1/4" nut driver, needle-nose pliers, fine steel wool or emery cloth (to clean rod if needed). Disconnect the wire lead, remove the mounting screw, swap the sensor, reconnect and confirm the furnace completes a full ignition cycle.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In-stock units ship the same business day from our warehouse.
