First check

1 Let it cool, then read the drive LED

On Amana AXV9S overcurrent / overheat is often a dirty coil, a failed OD fan, or a locked compressor — not a dead inverter. Clear airflow, confirm the OD fan, and read the drive LED before you order a control. Compressor to ground, heat sink, supply voltage. Weigh-in vs nameplate.

Expect: OD fan running. Coil clean. Drive LED decoded from THIS outdoor’s card.

The rest of the walkthrough is Diagnose.

On the plates

  • Compressor to ground, heat sink, supply voltage. Weigh-in vs nameplate.
  • These L-codes do not exist on 24ACC6. If you are looking at a contactor, you are on the wrong outdoor.
