OEM Carrier Flame Sensor for PG95XAT30040ABAA 95% Gas Furnace

The flame sensor in your Carrier PG95XAT30040ABAA is a single rectifying rod that sits directly in the burner flame and confirms to the control board that gas is actually igniting. It works by flame rectification: a tiny microamp current passes through the flame to ground, and the board uses that signal to keep the gas valve open. When the rod oxidizes or cracks, the signal drops below the board's threshold and the furnace lights for a few seconds, then shuts the gas off — the classic short-cycle. Homeowners typically notice burners that ignite and snuff out repeatedly, warm air that never lasts, or a furnace that locks out after three or four failed tries and flashes a flame-sense fault code. Specs: This is a stainless-steel/Kanthal sense rod with a porcelain insulator and a 1/4" quick-connect terminal. A healthy flame signal on this Carrier platform runs roughly 1–6 microamps DC; anything under about 0.5–1 µA will trip a lockout. The bracket and rod geometry are matched to the burner so the tip sits in the hottest part of the flame envelope. OEM vs Generic: Flame sensing is all about a clean, correctly positioned rod. OEM sensors use the exact rod length, bend, and insulator rating so the tip lands in the flame and reads a strong, stable signal. Generic rods often sit too short or use lower-grade alloy that oxidizes faster, giving you a weak signal, nuisance lockouts, and another no-heat call within a season. Install (difficulty 1/5): You need a 1/4" nut driver, fine emery cloth, and a multimeter that reads microamps to verify the new signal. Safety first — shut off the gas and kill power at the furnace switch before pulling the old rod. Ships same business day from our stocked warehouse on orders before 3 PM CST.
