Motor circuit failure

The 1 up-arrow, 6 down-arrow flash on a LiftMaster or Chamberlain opener is a motor-circuit failure — the logic board has detected a fault in the drive electronics themselves, not in the sensors or the low-voltage wiring you can reach. There's no alignment or wire trace that clears this one; the opener is reporting a hardware failure inside the head.

Power-cycle the opener once to rule out a one-off glitch, but if the code comes back, the honest path is a repair-versus-replace decision. Replacing a logic board or motor assembly is pro work, and on units past the 10-to-15-year mark a new opener — typically $400–$800 for the unit plus $250–$550 in installed labor — often beats sinking money into the old head. A tech can quote both so you're not guessing.

Meaning: The logic board detected a failure in the motor circuit itself — not wiring, not sensors, the drive electronics.
Likely fix: Power-cycle once to rule out a glitch. If the code returns, the logic board or motor assembly needs replacement — on units past 10–15 years, a new opener installed ($250–$550) usually beats the repair.
DIY or pro: Pro — board/motor replacement, and worth a repair-vs-replace quote on the whole unit.

Code tables vary by model year — confirm against your model's manual (model number is on the motor head, under the light lens). Unplug the opener before touching any wiring.
