OEM Carrier Flame Sensor (48GS400192) for Model PY3PPA042060AB

This is the genuine OEM Carrier flame sensor, part number 48GS400192, factory-specified for the Carrier PY3PPA042060AB gas furnace. The flame sensor is a critical safety component — it uses ionization/rectification technology to detect the presence of a burner flame during each heating cycle. When the furnace ignites, the flame produces a small microamp electrical signal that the sensor sends back to the control board to confirm combustion. If the board doesn't receive that signal within a few seconds, it cuts off the gas valve as a safety measure. A failed or carbon-fouled sensor is one of the most common reasons a furnace will fire up, then shut off after just 5–8 seconds, leading to a no-heat lockout condition.

  • Specs: 90° mounting angle | Approx. 4.9" L × 1.75" H | Includes mounting bracket | Factory OEM fit for Carrier/Bryant gas furnaces
  • OEM vs Generic: This is the genuine Carrier-manufactured sensor rod, ensuring correct microamp sensitivity and exact dimensional fit. Aftermarket sensors can read weak flame signals inconsistently, causing nuisance lockouts or masking true ignition problems.
  • Install Difficulty: 2/5 — Turn off gas and power before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers. Disconnect the single wire lead, remove the mounting screw, swap the sensor, and reconnect. Lightly sand the rod only if reusing a contaminated sensor — always install new when in doubt.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.

Compatibility: Designed and factory-matched for the Carrier PY3PPA042060AB gas furnace. Always verify part number 48GS400192 against your unit's data plate or wiring diagram before ordering. Our team is available to confirm fitment — just reach out before you buy. In stock — order now for same-day shipping.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY3PPA042060AB — 48GS400192?

How do I replace the flame sensor on my Carrier PY3PPA042060AB — 48GS400192?
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.
