OEM Carrier Flame Sensor (48GS400192) for Model PY2PPB048130AB

This is the genuine OEM Carrier flame sensor, part number 48GS400192, factory-specified for the Carrier PY2PPB048130AB gas furnace. The flame sensor is a critical safety component — its rod is positioned directly in the burner flame and uses ionization (flame rectification) to confirm combustion is occurring. When the sensor detects no flame signal, the control board locks out the gas valve to prevent unburned gas accumulation. A dirty or failed flame sensor is one of the most common causes of a furnace that ignites briefly and then shuts off after 5–8 seconds, often triggering a repeated lockout sequence.

• Specs: 90-degree mounting angle | Approx. 4.9" length × 1.75" height | Single-rod ionization type | OEM part number 48GS400192 | Compatible connector and bracket included
• OEM vs Generic: The genuine Carrier OEM sensor is manufactured to exact factory tolerances for rod alloy, bend angle, and connector fit — ensuring reliable microamp readings that a generic sensor may not consistently deliver, leading to nuisance lockouts or premature failure.
• Install Difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, soft cloth or fine steel wool (to clean rod if reusing). Disconnect the wire lead, remove the single mounting screw, swap the sensor, and reconnect. Total job: under 15 minutes for most technicians.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.
