OEM Carrier Flame Sensor (90° with Mounting Bracket) for Model PY3PEA048115NB

This is the factory OEM flame sensor for the Carrier PY3PEA048115NB gas furnace, sold under part number 48GS400192. The flame sensor is a critical safety component: after the hot surface igniter lights the burner, the flame rod detects the presence of combustion via electrical rectification and ionization. If the control board receives no confirming signal within a few seconds, it cuts gas flow and locks out the furnace — a built-in safeguard against unburned gas accumulation. A failed or contaminated sensor is one of the most common reasons a furnace fires briefly, then shuts off 5–8 seconds later, often triggering repeated lockout codes.

  • Part Number & Specs: OEM #48GS400192 | 90-degree rod angle | Includes mounting bracket | Dimensions approx. 4.9" × 1.75" × 1.6" | Factory-matched to Carrier PY3PEA048115NB control board signal range
  • OEM vs Generic: This is a genuine Carrier OEM part — not an aftermarket substitute. OEM sensors maintain the exact rod alloy composition and geometry required for proper microamp current readings. Generic sensors can drift out of spec, causing nuisance lockouts or false flame detection.
  • Install Difficulty: 2/5 — Disconnect power and gas before servicing. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers, fine steel wool or emery cloth (to clean rod if reusing). Swap takes under 15 minutes for most technicians. Always confirm flame sensor wire connector seats fully on the new rod.
  • Warranty & Shipping: Backed by a 1-year OEM manufacturer warranty against defects. In stock and ships same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement flame sensor for Carrier model PY3PEA048115NB. Always verify the OEM part number on your existing sensor or equipment data plate before ordering.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY3PEA048115NB?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY3PEA048115NB. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the flame sensor on my Carrier PY3PEA048115NB?
Difficulty: Easy (10–15 min)
Step 1: Turn off power/gas. Step 2: Open furnace panel. Step 3: Locate flame sensor rod near burners. Step 4: Remove single mounting screw. Step 5: Clean rod with 400-grit sandpaper until shiny (or replace). Step 6: Reinstall and tighten. Most common furnace repair — saves $150–$300 vs technician.
My furnace lights then shuts off after a few seconds. Why?
Furnace lights then shuts off after 3–10 seconds = dirty flame sensor in 90% of cases. The sensor can’t detect flame through oxidation buildup. Fix: clean with 400-grit sandpaper (free, 15 min). If cleaning doesn’t work, replace the sensor.
Is this flame sensor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier flame sensor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
