  • Indoor furnace universals (50A55, 50M56U, ICM282B, ICM2811, S9200U). This is not an IFC.
  • Do not ‘adapt’ a furnace board to an outdoor inverter, defrost PCB, or contactor.

After you pull the dead card

  1. 1Photograph the outdoor silk. Indoor 50A55 / ICM282B / S9200U do not belong here.
  2. 2Contactor units: replace the contactor / cap / HPS — there is no universal outdoor board.
  3. 3Inverter / communicating outdoors: OEM drive only. There is no White-Rodgers or ICM outdoor universal.

    Common

Prove it

  • Drive LEDs / display. There is no contactor to chase.
  • Charge is weigh-in + line-set.

Do not

  • Do not throw a dual run cap.
  • Do not ohm a defrost sensor. That is GSZC / ASZC.

Same 1/2 pair as GSXC18. The outdoor is a drive, not a two-stage scroll board.

Sequence

  1. 1

    Call

    Indoor requests capacity. Inverter ramps. No contactor.

  2. 2

    Protect

    HPS / LPS / drive OC. AC-only — no defrost.

Faults on this IFC

Step 1, then 2, then 3. Expected reading and the fail branch sit under each check.

Comm

ABCD / outdoor drop

lockout

Drive or bus. Wall control loses the outdoor.

  1. 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. ABCD landing and polarity, outdoor board power, inverter comms harness.

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

  2. 2 Voltage and compressor windings

    Incoming voltage in range (this plate’s line-voltage code). Compressor windings even, no ground. A shorted compressor will kill a new drive. C still required at the wall control.

    Expect: Balanced windings. No winding to ground. Line voltage stable under load.

  3. 3 Charge and the drive last

    A starved or flooded compressor will overcurrent. Confirm SH/SC and charge weight. Only then condemn the inverter. Indoor must be Infinity-capable. A 24ACC6-style indoor pairing is the wrong mental model.

    Expect: Charge on the nameplate. Drive code gone after a cool-down and a clean coil.

HPS / LPS

Pressure protection

lockout

Still real on an inverter.

  1. 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. Coil, fan, charge by weigh-in — you do not ‘top off’ a Greenspeed.

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

  2. 2 Voltage and compressor windings

    Incoming voltage in range (this plate’s line-voltage code). Compressor windings even, no ground. A shorted compressor will kill a new drive. Outdoor fan that is actually the inverter-driven fan, not a dual-cap PSC motor.

    Expect: Balanced windings. No winding to ground. Line voltage stable under load.

  3. 3 Charge and the drive last

    A starved or flooded compressor will overcurrent. Confirm SH/SC and charge weight. Only then condemn the inverter. Do not use 24ACC6 piston superheat as the pass/fail.

    Expect: Charge on the nameplate. Drive code gone after a cool-down and a clean coil.

Inverter

Drive overcurrent / overheat

lockout

L5/L4-class faults on the drive.

  1. 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.

  2. 2 Voltage and compressor windings

    Incoming voltage in range (this plate’s line-voltage code). Compressor windings even, no ground. A shorted compressor will kill a new drive. These L-codes do not exist on 24ACC6. If you are looking at a contactor, you are on the wrong outdoor.

    Expect: Balanced windings. No winding to ground. Line voltage stable under load.

  3. 3 Charge and the drive last

    A starved or flooded compressor will overcurrent. Confirm SH/SC and charge weight. Only then condemn the inverter.

    Expect: Charge on the nameplate. Drive code gone after a cool-down and a clean coil.

Workflows

Silent AXV9S

Indoor calling, outdoor not ramping.

  1. 1 Prove the call and the live code

    Drive LEDs. No contactor to chase.

    Expect: Write whatever Outdoor inverter (Amana badge) is showing. Outdoor display before disconnect.

    If fail: No call at the IFC → stat / harness. Do not change gas parts.

  2. 2 Isolate the first failed step in the sequence

    AMVC / AVPTC = data pair. AR9T96 = 24V Y.

    Expect: Protect: HPS / LPS / drive OC. AC-only — no defrost.

  3. 3 Confirm with a number, then the next part

    Weigh-in. Not an ASX16 top-off.

    Expect: Charge: Recover and weigh. Nameplate + ounces/ft. Not piston SH. · ABCD: Communicating to the Infinity indoor / 59MN7 family. D is not Y.

    If fail: Stay on this plate. The out-of-range reading is the part.

    If pass: Reading in range → the next step in this workflow is the repair.
