OEM Carrier Flame Sensor 48GS400192 for Packaged Unit PY2PPB030040AA

This is the genuine OEM flame sensor (flame rod) for the Carrier PY2PPB030040AA packaged gas/electric unit. The flame sensor is a critical safety component in the burner assembly — it detects the presence of a burner flame by passing a small electrical current through the flame itself. If the control board doesn't receive confirmation of a live flame within a few seconds of ignition, it immediately cuts gas flow as a safety measure. A failed or fouled flame sensor is one of the most common causes of a system that appears to light, then shuts off after just 5 to 8 seconds, triggering a lockout fault code.

  • OEM Part Number: 48GS400192 | Genuine Carrier factory replacement | Direct drop-in fit for model PY2PPB030040AA — no modifications required
  • OEM vs Generic: The OEM flame rod uses factory-spec stainless steel rod alloy and ceramic insulator rated for the exact microamp signal range your control board expects. Aftermarket sensors often read outside the tolerance window, causing nuisance lockouts even after installation.
  • Install Difficulty: 2/5 — Shut off gas and 24V power before starting. Tools needed: 1/4" nut driver, flat-head screwdriver, multimeter (to verify microamp signal 1–10 µA). Lightly sand the rod with fine steel wool if the original sensor is fouled before condemning it. Always verify lockout fault codes are cleared after replacement.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Carrier PY2PPB030040AA packaged gas/electric unit (2.5 ton, 40 MBH heat). Always cross-reference OEM part number 48GS400192 against your unit's wiring diagram or data plate to confirm fitment before installation. Have a question about compatibility?

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY2PPB030040AA?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY2PPB030040AA. 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 PY2PPB030040AA?
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.
