The genuine OEM Lennox 12U82, also cross-referenced as part 104358-01, is an outdoor fan power circuit board that powers and controls the condenser fan motor in your Lennox outdoor unit. It delivers the regulated power and control logic needed to start and modulate the fan, maintaining the airflow across the outdoor coil that is essential for proper heat transfer in cooling and heat-pump modes.

Common failure symptoms: A failing board may leave the outdoor fan dead, stuck at one speed, short-cycling, or intermittently dropping out. Secondary signs include rising head pressure, compressor overheating and lockouts, weak cooling, and system fault codes. Physical evidence such as bulging capacitors, burnt traces, or a scorched odor on the module indicates it should be replaced promptly to protect the compressor.

Why OEM matters: The Lennox 12U82 is built to the precise electrical rating, connector layout, and fan-control programming your equipment expects. Generic replacements often introduce speed-mapping errors or wiring mismatches that trigger nuisance faults and shorten component life. Installing the authentic factory part ensures direct fit, correct fan operation, and the reliability designed into your Lennox system. Restore dependable outdoor fan performance with the genuine OEM board.

Frequently Asked Questions

Does this Control Board fit my Lennox OEM Lennox Outdoor Fan Power Circuit Board — 12U82?

How do I replace the control board on my Lennox OEM Lennox Outdoor Fan Power Circuit Board — 12U82?
Difficulty: Advanced (1–2 hrs)

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 Lennox parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation.

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 Lennox 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.
