OEM Carrier Flame Sensor for Model GB3AAV048115AGJA Gas Furnace

This genuine OEM Carrier flame sensor is the exact factory replacement for your GB3AAV048115AGJA gas furnace. The flame sensor confirms a flame is present immediately after ignition and signals the control board to keep the gas valve open — an essential safety check. When the sensing rod becomes coated, corroded, or worn, the burner lights and then shuts off within seconds, producing frustrating short-cycling and a cold home. A new sensor restores steady, reliable ignition. This part meets Carrier's specification for the GB3AAV048115AGJA, with the correct rod length, mounting, and microamp output. Installation is rated easy: switch off power and gas, remove one mounting screw, unplug the wire lead, and install the new sensor in roughly 10 minutes. Genuine OEM prevents the weak-signal lockouts frequently caused by universal replacements. This is the most common and least expensive fix for a furnace that won't stay lit. In stock and ships same-day on orders placed before 3PM CST. Get safe, dependable heat back with the correct Carrier flame sensor for your model.

How do I replace the flame_sensor on my Carrier Model GB3AAV048115AGJA Gas Furnace?

My furnace lights then shuts off after a few seconds. Why?
Furnace lights then shuts off after 3–10 seconds = dirty flame sensor in 90% of cases. The sensor can’t detect flame through oxidation buildup. Fix: clean with 400-grit sandpaper (free, 15 min). If cleaning doesn’t work, replace the sensor.
Is this flame_sensor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier flame_sensor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
