OEM Carrier Integrated Furnace Control Board for U19X080UW36B

The integrated furnace control board is the command center of your Carrier furnace, orchestrating the ignition sequence, inducer draft motor, gas valve, and blower based on thermostat demand and feedback from the limit and flame-sense safeties. As it fails, the signs are unmistakable: short-cycling, a blower that runs nonstop or won't engage, no response to a heat call, or a unit that ignites briefly and then drops into lockout. A flashing diagnostic LED logging a limit or flame fault while those parts test good is the classic symptom of a failing board. This OEM board includes the full onboard relay complement — inducer, gas valve, and 120 VAC heat/cool blower taps — and the exact line- and low-voltage terminal strip that mates to the U19X080UW36B wiring harness. It comes pre-flashed with the correct ignition timing, flame-sense threshold, and soft-lockout logic for this model, programming a universal board cannot match. The control circuit runs 24 VAC against a 120 VAC line input. Why OEM matters here: a generic board might mount up but operate on different relay ratings and timing, producing nuisance lockouts, prematurely welded relays, or an inducer that drops out mid-cycle. Matched firmware shields the gas valve and igniter from mistimed energizing that erodes their lifespan. Install difficulty: 3 of 5. You'll want a 1/4" nut driver, a #2 Phillips, needle-nose pliers, and a multimeter, and a photo of the wiring before removal. Safety first — cut the furnace breaker and confirm zero voltage before disconnecting any leads; the board is energized at line voltage. Ships same business day from our stocked warehouse on orders placed before 3 PM CST. Backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.

Compatibility

This part is compatible with Carrier model U19X080UW36B. Always verify the part number against your unit's data plate before ordering.

Why Choose OEM?

OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.

Shipping & Returns

Frequently Asked Questions

Does this Control Board fit my Carrier U19X080UW36B?
Yes. This is the factory-specified OEM control board for the Carrier U19X080UW36B. 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 control board on my Carrier U19X080UW36B?
Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.
My HVAC system is completely dead. What could be wrong?
Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.
Is this control board 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 control board?
OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
How fast does National HVAC Parts ship?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
