OEM Carrier Flame Sensor LH33WZ521 / LH680534 for Model PG92SCS48060BAAA

This is the genuine OEM Carrier flame sensor — stocked under part numbers LH33WZ521 and the updated superseding number LH680534 (Flame Sensor w/Lead) — factory-specified for the Carrier PG92SCS48060BAAA gas furnace. The flame sensor is a critical safety component: it generates a small electrical current through the burner flame to prove ignition to the integrated furnace control (IFC) board. When the sensor is fouled with oxidation or has failed completely, the furnace will light briefly and then shut off after just 5 to 8 seconds, triggering a lockout code. Replacing the flame sensor is one of the most common and cost-effective furnace repairs.

  • OEM Part Numbers: LH33WZ521 (Flame Sensor) | LH680534 (Flame Sensor w/Lead) — both are factory-authorized for this model. LH680534 is the current superseding number and includes a lead wire for drop-in installation.
  • OEM vs. Generic: Genuine Carrier OEM sensors are manufactured to exact rod-length, bracket angle, and alloy specifications. Aftermarket sensors can have incorrect geometry or inferior rod coatings, leading to nuisance shutdowns and repeat service calls.
  • Install Difficulty: 1/5 — The simplest furnace repair. Tools needed: 1/4" hex driver (1 screw), fine steel wool or emery cloth to clean the rod if reusing, and a multimeter to verify microamp output post-install. Always shut off gas and power before servicing.
  • Warranty: 1-year OEM manufacturer warranty from date of purchase. In-stock orders ship same business day when placed before cutoff.

Compatibility: Designed for the Carrier PG92SCS48060BAAA gas furnace. This part also cross-references several legacy Carrier flame sensor numbers including LH680014, LH680012, LH33WZ511, LH33WZ515, and LH33WZ517 — confirm your existing part number or model data plate before ordering. Our team is available to verify fitment prior to purchase.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PG92SCS48060BAAA?
Yes. This is the factory-specified OEM flame sensor for the Carrier PG92SCS48060BAAA. 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 PG92SCS48060BAAA?
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.
