OEM Carrier 90° Flame Sensor with Mounting Bracket for Model PY2PNB060130AA (Part# 48GS400192)

This is the genuine OEM Carrier flame sensor (part number 48GS400192), factory-specified for the Carrier PY2PNB060130AA gas furnace. The flame sensor — also called a flame rod — uses ionization/rectification technology to confirm that a burner flame is present after ignition. When it detects the flame's electrical signal, it tells the control board to keep the gas valve open. A failed or contaminated sensor cannot confirm ignition, causing the furnace to lock out after just 5–8 seconds of operation. If your furnace lights briefly, then shuts off and repeats this cycle, a faulty flame sensor is the most common culprit.

• Specs: 90-degree rod configuration | Includes factory mounting bracket | Approx. dimensions: 4.9" H × 1.75" W × 1.6" L | OEM part number 48GS400192 | Carrier-genuine construction
• OEM vs Generic: This is a genuine Carrier OEM part — not an aftermarket approximation. OEM flame sensors use factory-grade stainless rod alloys and exact bracket geometry, ensuring reliable ionization current readings. Generic sensors can produce inconsistent microamp signals, leading to nuisance lockouts even after installation.
• Install difficulty: 2/5 — Power down and wait for the furnace to cool before servicing. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers, and a multimeter capable of reading microamps (µA) to verify sensor output after install (typically 2–6 µA). Lightly clean the rod with fine steel wool if reusing; always replace if cracked or heavily oxidized.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse — order by 3 PM local time for next-day arrival in most areas.
