OEM Carrier Flame Sensor (48GS400192) for Model PY3PPA036060AA

This is the genuine OEM Carrier flame sensor for the PY3PPA036060AA packaged gas unit. The flame sensor — also called a flame rod — is a critical safety component that monitors burner ignition via electrical rectification. When your burner lights but the furnace shuts down within 5 to 8 seconds, a failed or carbon-coated flame sensor is almost always the culprit. The control board receives no confirming signal and triggers a safety lockout to prevent unburned gas accumulation. Replacing this sensor with the correct OEM part restores proper flame-proving performance and eliminates nuisance lockouts.

• Specs: 90° mounting bracket | Flame rod sensor type | OEM part number 48GS400192 | Dimensions approx. 4.9" L × 1.75" H | Factory-matched for Carrier PY3PPA036060AA
• OEM vs Generic: Genuine Carrier OEM sensors meet exact rod geometry, alloy grade, and bracket angle specifications. Off-brand sensors may produce weak or intermittent microamp signals, causing persistent lockouts even after cleaning.
• Install Difficulty: 2/5 — Turn off gas and power at the disconnect before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, and a multimeter (to verify microamp draw post-install). Lightly sand the rod with fine steel wool if reusing is attempted, or install this new OEM unit for a guaranteed fix. Always photograph wire routing before disconnecting.
