OEM Carrier Flame Sensor (48GS400192) for Model PY1PPB036060NBAA

This OEM flame sensor is the factory-specified replacement for the Carrier PY1PPB036060NBAA gas furnace. The flame sensor (also called a flame rod) uses electrical rectification to confirm that a burner flame is present after ignition. When the sensor rod detects ionization from the flame, it sends a microamp signal to the control board allowing the gas valve to stay open. A failed or contaminated flame sensor cannot produce a reliable signal — causing the furnace to lock out on a safety fault, typically shutting off 5 to 8 seconds after ignition and repeating the cycle without ever sustaining heat.

• Specs: 90° mounting angle | Includes mounting bracket | Factory-matched microamp output | OEM Part Number: 48GS400192
• OEM vs Generic: This is a genuine Carrier OEM part with factory-calibrated rod composition and coating. Generic sensors can exhibit inconsistent microamp output, leading to nuisance lockouts even when the burner is functioning correctly.
• Install difficulty: 2/5 — Turn off gas supply and 120V power before servicing. Tools needed: 1/4" nut driver, fine steel wool or emery cloth (to clean rod if reusing), multimeter (to verify microamp draw). Disconnect the single wire connector, remove one mounting screw, swap the sensor, and reconnect. Light cleaning of the new rod's tip with emery cloth is recommended before installation.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In stock — ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY1PPB036060NBAA gas furnace. Always verify your existing sensor's mounting angle and connector type against your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.
