OEM Carrier Flame Sensor LH33WZ005 for Model PY1PEA048080AFBA

This is the OEM factory-specified flame sensor (flame rod) for the Carrier PY1PEA048080AFBA packaged gas/electric unit. The flame sensor's job is critical: it detects the presence of a burner flame by passing a small electrical current through the rod and into the flame itself. If the control board doesn't detect that current within a few seconds of ignition, it shuts off the gas valve as a safety measure. A coated, corroded, or failed sensor is one of the most common causes of a furnace that lights, runs briefly for 5–8 seconds, then shuts down and locks out — cycling repeatedly without ever sustaining heat.

• Specs: OEM Part Number LH33WZ005 | Factory-matched flame rod geometry and ceramic insulator | Correct bracket mounting configuration for Carrier packaged units
• OEM vs Generic: OEM sensors use the exact rod alloy and ceramic insulator specification Carrier's control board expects. Off-brand sensors can produce weaker microamp signals, causing nuisance lockouts even with a clean rod — OEM eliminates that variable entirely.
• Install Difficulty: 2/5 — Turn off gas and power at the disconnect before servicing. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers. Simply unplug the single wire connector, remove the mounting screw, swap the sensor, and reconnect. Always verify microamp reading (1.5–4.0 µA typical) with a multimeter after installation.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
