OEM Carrier 90° Flame Sensor 48GS400192 for Model PY3PPA060130NB

This OEM Carrier flame sensor (part #48GS400192) is the factory-specified replacement for the Carrier PY3PPA060130NB gas furnace. The flame sensor — also called a flame rod — is a critical safety component that detects whether a burner flame is actually present after ignition. It does this through a process of flame rectification: the rod passes a small AC current through the flame, and the ionized combustion gases allow DC current to flow back, confirming ignition to the control board. When this sensor fails, the furnace will light briefly then shut down after just 5–8 seconds, cycling through repeated lockouts and leaving your home without heat.

• Specs: 90-degree angle rod with factory mounting bracket | Compact form factor (approx. 4.9" L × 1.75" H) | Direct OEM replacement — no modifications required
• OEM vs Generic: This is a genuine Carrier OEM part, manufactured to exact factory tolerances for signal sensitivity and rod geometry. Generic sensors can produce weak or inconsistent microamp readings, causing nuisance shutdowns even when the burner flame is healthy.
• Install Difficulty: 2/5 — A straightforward single-wire swap accessible through the burner compartment. Tools needed: 1/4" nut driver or 5/16" wrench, needle-nose pliers. Always shut off gas and 120V power before servicing. Clean the rod with fine steel wool if reinstalling an old sensor.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.
