OEM Carrier Flame Sensor 48GS400192 for Model PY3PEA060090AB

This is the factory OEM replacement flame sensor (also called a flame rod) for the Carrier PY3PEA060090AB packaged unit. The flame sensor is a safety-critical component that detects the presence of a burner flame by passing a small electrical current through the rod into the flame. If the furnace or heating section lights, runs for 5–8 seconds, and then shuts off — often repeating in lockout cycles — a dirty or failed flame sensor is the most common cause. Replacing this part with the correct OEM unit restores reliable ignition and prevents nuisance shutdowns.

• Specs: OEM Part# 48GS400192 | Factory flame rod assembly | Exact-fit bracket and ceramic insulator | Matched to Carrier factory micro-amp sensing thresholds
• OEM vs Generic: This is a genuine Carrier OEM part. OEM flame sensors maintain precise micro-amp output tolerances required by the control board. Generic alternatives can produce erratic readings, causing premature lockout or, worse, delayed shutoff.
• Install Difficulty: 2/5 — Turn off gas supply and 24V power before beginning. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, and a multimeter (to verify micro-amp output post-install). Photograph the existing wiring connector before removal. The sensor mounts directly in the burner assembly and connects via a single wire lead.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
