OEM Carrier Flame Sensor 48GS400192 for Model PY3PNA060115AB

This OEM flame sensor (part# 48GS400192) is the factory-specified replacement for the Carrier PY3PNA060115AB packaged gas/electric rooftop unit. The flame sensor is a safety-critical component — a small metal rod that detects the presence of a burner flame by passing a micro-amp electrical current through it to ground. When the sensor is dirty, cracked, or failed, the control board cannot confirm ignition and will shut off the gas valve within 5–8 seconds of every ignition attempt, resulting in a no-heat lockout condition.

• Specs: OEM flame rod design | Factory-matched micro-amp sensing range | Direct plug-in connector | Rated for high-temperature burner environments in packaged rooftop applications
• OEM vs Generic: This is a genuine OEM Carrier part, manufactured to exact factory tolerances. Generic flame sensors can exhibit inconsistent micro-amp output, causing nuisance lockouts even on a clean burner — leading to repeat service calls and unnecessary downtime.
• Install Difficulty: 2/5 — Shut off gas and 24V power before servicing. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers. Disconnect the wire lead, remove the single mounting screw, swap the sensor, and confirm secure seating in the burner bracket. Tip: Never touch the ceramic rod with bare hands — skin oils degrade performance.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
