OEM Carrier Flame Sensor Assembly LH33WZ005 for Model PY1PNA060080ADBA

This is the genuine OEM Carrier flame sensor assembly (part number LH33WZ005), factory-specified for the Carrier PY1PNA060080ADBA gas furnace. The flame sensor — also called a flame rod — is a critical safety component that detects the presence of a burner flame and sends a microamp signal to the control board confirming safe ignition. When the sensor becomes coated with oxidation or fails entirely, the control board cannot verify combustion and will shut down the gas valve within 5–8 seconds of ignition, triggering a lockout fault. The symptom is a furnace that lights briefly then immediately shuts off, often repeating 2–3 times before locking out entirely.

• Specs: Genuine OEM Carrier flame sensor assembly | 64-1/2" lead wire | Factory-matched microamp output | Direct drop-in replacement for LH33WZ005
• OEM vs Generic: OEM sensors are calibrated to exact microamp tolerances required by the Carrier control board. Aftermarket sensors may produce marginal readings that cause nuisance lockouts or, worse, fail to detect a true loss-of-flame condition — a safety risk. Always use OEM on gas-fired appliances.
• Install difficulty: 2/5 — Turn off gas and 120V power before servicing. Tools needed: 1/4" hex driver or nut driver, fine steel wool or emery cloth (to clean rod if reusing), multimeter with microamp DC range. Disconnect the single wire connector, remove the one mounting screw, swap the sensor, and reconnect. Clear any lockout fault by cycling the thermostat.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
