OEM Carrier Flame Sensor (48GS400192) for Model PY3PEA048130AA

This OEM 90-degree flame sensor with mounting bracket is the factory-specified replacement for the Carrier PY3PEA048130AA gas furnace. The flame sensor is a critical safety component: after the igniter lights the burners, this sensor generates a microamp DC signal through the flame to confirm combustion is active. If the control board does not receive that signal within a few seconds, it will shut off the gas valve and lock out the furnace as a safety precaution. A dirty, cracked, or failed flame sensor is one of the most common causes of a furnace that starts, runs for 5–8 seconds, then shuts off — often leading to a no-heat call in the middle of winter.

• Specs: 90-degree rod configuration | Includes factory mounting bracket | OEM part number 48GS400192 | Carrier-matched microamp sensing range
• OEM vs Generic: This is a genuine Carrier OEM part — factory-matched rod alloy and geometry ensure accurate flame rectification signal. Generic sensors can produce inconsistent microamp readings, causing nuisance lockouts or, worse, delayed safety shutoffs.
• Install Difficulty: 2/5 — A straightforward single-wire swap with one mounting screw. Tools needed: flat-head and Phillips screwdriver, fine steel wool or emery cloth (to clean rod before install if reusing bracket), and a multimeter (optional, to verify microamp signal). Always turn off power and gas before servicing.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse.
