This OEM Carrier flame sensor assembly (part# LH33WZ005) is the factory-authorized replacement for the Carrier PY1PNA030080ACBA gas furnace. The flame sensor — also called a flame rod — is a critical safety component that sends a small microamp signal to the control board confirming that a burner flame is present. When it fails or becomes coated with oxidation, the control board cannot verify ignition and will shut off the gas valve within 5 to 8 seconds as a safety lockout. The result: your furnace lights briefly, then goes out repeatedly until the system locks out entirely.
Compatibility: Designed for the Carrier PY1PNA030080ACBA gas furnace. Verify your unit's data plate and existing part number before ordering — our team is available to confirm fitment. Questions about compatibility? Contact us before you order and we'll verify the fit.
