OEM Carrier Flame Sensor Replacement for PG8UAA060135ADJA Furnace

The flame sensor is a thin metallic rod that sits directly in the burner flame and confirms ignition has actually occurred. In your Carrier PG8UAA060135ADJA gas furnace it generates a tiny microamp current that tells the control board a flame is present; the instant that signal disappears, the board closes the gas valve within seconds as a safety lockout. When the rod becomes coated with carbon and oxidation — or cracks — you'll notice the classic symptom: the furnace lights, runs for 3–7 seconds, then shuts off and tries again (short-cycling). Other signs are repeated ignition clicks, lukewarm air, and eventually a hard lockout with no heat at all. A weak flame signal is one of the most common no-heat service calls. This sensor uses a high-temperature alloy rod with a porcelain insulator rated for continuous burner exposure. A healthy unit reads roughly 0.5–6 microamps of DC flame current once lit; below about 0.5 µA the board drops out. Resistance from the rod to ground should read effectively open when cool — any continuity signals a cracked insulator. Rod length and bend angle position the tip in the hottest part of the flame. Generic sensors often use lower-grade alloys that oxidize faster and rods that sit slightly outside the flame envelope, producing a marginal signal that works on day one but drifts below the dropout threshold within a season, bringing the short-cycling right back. The OEM Carrier sensor matches the original geometry and insulator rating so flame current stays solid. Install difficulty: 1/5. Tools: 1/4" nut driver, fine emery cloth or steel wool, multimeter set to DC microamps. #1 safety warning: turn off the gas and kill power at the furnace switch before reaching into the burner area — never service the burner assembly with gas live.

Compatibility

This part is compatible with Carrier model PG8UAA060135ADJA. Always verify the part number against your unit's data plate before ordering.

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.

Shipping & Returns

Same-day shipping on orders before 3 PM CST. Standard delivery 2-5 business days, express options available at checkout. 30-day hassle-free returns on uninstalled parts — free return shipping included. 1-year OEM factory warranty coverage.
