OEM Carrier Gas Furnace Flame Sensor Rod for PG9MTAV36050ABSS

The flame sensor is the safety device that proves your Carrier PG9MTAV36050ABSS furnace actually lit. Once the burners ignite, this thin metal rod sits directly in the flame and generates a tiny microamp current through flame rectification, telling the control board that real fire is present. When the rod becomes coated with oxidation and carbon — or corrodes with age — it can no longer 'see' the flame. The signature symptom is a furnace that lights normally, runs for 3 to 7 seconds, then shuts the gas off and tries again, short-cycling several times before locking out and leaving you with no heat. This OEM-spec single-rod flame sensor is built for the PG9MTAV burner assembly with the correct rod length, bend, and ceramic insulator so the tip sits in the proper part of the flame. Output is measured in microamps: a clean, properly positioned rod typically reads about 1–6 µA on a meter set to DC microamps, and most Carrier boards drop out below roughly 0.5–1 µA. The mounting-hole spacing and spade terminal match the factory sensor for a plug-and-play swap. Flame sensors look simple, but rod metallurgy and exact placement are what keep the signal strong. Cheap generic rods use lower-grade alloys that oxidize and lose conductivity faster, and slight differences in rod length or angle move the tip out of the hottest part of the flame — both of which mean more nuisance lockouts and another no-heat service call. An OEM sensor holds a stable flame signal far longer between cleanings. Installation difficulty: 1 of 5 (about 10 minutes). Tools: a 1/4" nut driver to remove the single mounting screw, and optionally a multimeter for a microamp reading. Safety first: kill power to the furnace at the breaker before servicing — the sensor sits inches from a live burner. Never sand a new sensor with rough sandpaper; if cleaning the old one, use fine steel wool or emery cloth only. Ships same business day from our stocked warehouse on orders placed before 3 PM CST. Backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.

Compatibility

This part is compatible with Carrier model PG9MTAV36050ABSS. 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.
