OEM Carrier Gas Furnace Flame Sensor Rod for PG8DAA036050AAJA

On your Carrier PG8DAA036050AAJA, the flame sensor is the burner's proof-of-flame safety. Once the hot surface igniter glows and the gas valve opens, this slim rod is bathed in the flame and conducts a minute rectified current — just a few microamps — back to the integrated control board to confirm combustion. If the board doesn't 'see' that current, it closes the gas valve within seconds to prevent raw gas from filling the heat exchanger. As the rod accumulates a film of oxidation or soot, the signal fades and the furnace begins short-cycling: ignites, runs a few seconds, drops out, retries, and eventually locks out — leaving the house cold and the diagnostic LED flashing. Specs: A single-rod sensor with a ceramic standoff insulator and a heat-resistant alloy probe sized for continuous flame immersion. Measured in operation it should produce about 1-5 microamps DC of flame current; readings below roughly 0.5 µA cause nuisance lockouts. The bracket footprint and male spade terminal are a direct match for the Carrier/Bryant burner assembly. OEM vs Generic: A flame sensor's job depends on stable rectification, which comes from the rod's exact alloy and surface area. Cheaper generic rods oxidize quickly and put out a marginal signal from day one, so the short-cycling returns far sooner. The OEM rod is positioned and sized for a strong, lasting flame current. Install: Difficulty 2/5. Tools: 1/4" nut driver, fine abrasive pad for cleaning, multimeter on DC microamps. SAFETY: Close the gas shutoff and switch off the breaker before removing anything near the burners. Ships same business day from our stocked warehouse on orders placed before 3 PM CST.

Why Choose OEM?

OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.
