OEM Carrier Hot Surface Igniter Replacement Kit 331930-751 for Model PG8MAA036070AAJA

This is the genuine OEM Carrier hot surface igniter replacement kit (part #331930-751) factory-specified for the Carrier PG8MAA036070AAJA gas furnace. The hot surface igniter is the critical component that glows red-hot to ignite the gas burner on every heating cycle. When it fails, the furnace will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat. This kit upgrades to a durable silicon nitride igniter, replacing the older silicon carbide style (LH33ZS004) used in many 33" tall furnace models, and includes everything needed for a clean, professional installation.

  • Specs: 120V AC hot surface igniter | Silicon nitride element | Operating voltage: 98–132 VAC | Time to ignition temperature: <17 seconds @ 120V | Cold resistance: 34–64 Ohms @ 75°F | OEM Part #331930-751
  • Kit Includes: Silicon nitride igniter element, mounting bracket, OEM-matched connector, and high-temperature wire nuts — a complete drop-in upgrade solution with no additional hardware required.
  • OEM vs Generic: This genuine Carrier OEM kit is factory-calibrated to the exact voltage and thermal rise curve of your PG8MAA036070AAJA furnace control board. Generic igniters may operate outside tolerance, causing nuisance lockouts or premature element failure.
  • Install Difficulty: 2/5 — Turn off gas and electrical supply before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, multimeter (to verify cold resistance). Allow igniter to cool fully before handling. Typical install time: 20–30 minutes.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse on all in-stock orders.

Compatibility: Designed as the direct OEM replacement for Carrier PG8MAA036070AAJA gas furnaces. Also cross-references part numbers LH33ZS004 and LH33ZG001 on compatible 33" tall Carrier, Bryant, and Payne furnace models. Always verify your unit's existing igniter voltage and part number on the data plate before ordering. Our fitment specialists are standing by to confirm compatibility before you buy — order now for same-day shipping!

Frequently Asked Questions

Does this Igniter fit my Carrier PG8MAA036070AAJA?
Yes. This is the factory-specified OEM igniter for the Carrier PG8MAA036070AAJA. 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 igniter on my Carrier PG8MAA036070AAJA?
Difficulty: Medium (20–30 min)
Step 1: Turn off power and gas. Step 2: Open furnace panel. Step 3: Locate igniter near burners. Step 4: Disconnect two-wire plug. Step 5: Remove mounting screw. Step 6: Install new igniter — do NOT touch element with fingers. Step 7: Reconnect, close panel, restore power/gas.
My furnace won’t ignite. What part is bad?
Furnace won’t ignite after the draft inducer runs = failed igniter. The hot surface igniter should glow bright orange within 60 seconds. No glow = cracked/burned out. Weak glow = degrading. Average lifespan: 3–7 years. Replacement: $15–$40 DIY.
Is this igniter 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 igniter?
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.
